What is an interesting fact about Newton's first law?
The first law says that any object in motion will continue to move in the same direction and speed unless forces act on it. That means if you kick a ball it will fly forever unless some sort of forces act on it! As strange as this may sound, it's true. When you kick a ball, forces start to act on it immediately.
Newton's first law explains how things move and how forces work on their movement, which makes it an extremely important discovery. If we were to place an object into space, we could observe how it behaves without any external influences. The force that is exerted upon an object can be either external or internal.
Newton's first law: An object at rest remains at rest, or if in motion, remains in motion at a constant velocity unless acted on by a net external force.
What does Newton's first law state? A body at rest tends to remain at rest and a body in motion tends to remain in motion at a constant acceleration unless acted on by a net external force.
The acceleration is directly proportional to the net force; the net force equals mass times acceleration; the acceleration in the same direction as the net force; an acceleration is produced by a net force.
The laws are: (1) Every object moves in a straight line unless acted upon by a force. (2) The acceleration of an object is directly proportional to the net force exerted and inversely proportional to the object's mass. (3) For every action, there is an equal and opposite reaction.
In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.
Answer. Answer: Newton's first law of motion tells us that any object in motion will remain in motion till any outside force is applied and it helps our satellites to travel in space without fuel so it saves our money.
The condition is described by the phrase "... unless acted upon by an unbalanced force." As the long as the forces are not unbalanced - that is, as long as the forces are balanced - the first law of motion applies.
A body remains in the state of rest or uniform motion in a straight line unless and until an external force acts on it. Putting Newton's 1st law of motion in simple words, a body will not start moving until and unless an external force acts on it.
Why is it called Newton's first law?
It is called the law of inertia because it tells that every material body has a property by virtue of which it resists the change in its state of rest or in its state of motion. This property is called inertia.
We can give Newton's first law in vector form: v → = constant when F → net = 0 → N . v → = constant when F → net = 0 → N . This equation says that a net force of zero implies that the velocity v → v → of the object is constant.
If you jump from a car or bus that is moving, your body is still moving in the direction of the vehicle. When your feet hit the ground, the grounds act on your feet and they stop moving. You will fall because the upper part of your body didn't stop, and you will fall in the direction you were moving.
Newton was also influenced by Descartes. He is said to have taken the form of his law from Descartes' first law of nature: … each particular part of matter continues always to be in the same state unless collision with others constrains it to change that state.
Thus, the specific Newton's law that best explains why motorists should buckle up is (d) the first law.
Example 1: When a car stops suddenly, the passengers still feel forward motion. This is due to the inertia of motion whereby the car begins to stop while the body inside is still in a state of motion.

Newton's Laws of Motion are three physical laws which provide relationships between the forces acting on a body and the motion of the body, first formulated by Sir Isaac Newton. Newton 's laws were first published in his work Philosophiae Naturalis Principia Mathematica (1687).
For example, if the Earth is pulling down on you with a gravitational force of 500 N, you are also pulling up on the Earth with a gravitational force of 500 N. This remarkable fact is a consequence of Newton's third law.
In a naive or very general sense, it appears that Newton's combined first and second law, F = ma , does not always work. On a fairground ride such as a merry-go-round, or on a turning bus, unrestrained objects have unexplained horizontal accelerations.
How is Newton's law used in real life?
When you jump, your feet apply force to the ground, and the earth applies an equal and opposite reaction force that pushes you into the air. When a person is in water, the water pushes the person forward while the person pushes the water back, both affect each other.
In his Principia Mathematica, Newton says that a force causes an acceleration. Without the first law, this doesn't necessarily imply that zero force means zero acceleration. One could conceive of other things that also cause acceleration. A modern person might be concerned about non-inertial reference frames.
Inertia is the tendency of all objects to resist any change in motion. Inertia causes a moving object to stay in motion at the same velocity (speed and direction) unless a force acts on it to change its speed or direction. It also causes an object at rest to stay at rest.
Friction is a force that slows or stops motion.
Newton's First Law of Productivity. First Law of Motion: An object either remains at rest or continues to move at a constant velocity, unless acted upon by an external force. (i.e. Objects in motion tend to stay in motion.
Inertia is the force that holds the universe together. Literally. Without it, matter would lack the electric forces necessary to form its current arrangement. Inertia is counteracted by the heat and kinetic energy produced by moving particles.
Newton's first law of motion is often called the law of inertia because inertia is the tendency of an object to resist a change in its motion.
- One's body movement to the side when a car makes a sharp turn.
- Tightening of seat belts in a car when it stops quickly.
- A ball rolling down a hill will continue to roll unless friction or another force stops it.
- If pulled quickly, a tablecloth can be removed from underneath of dishes.
Hence we can conclude that another name for Newton's first law of motion is Galileo's law of inertia.
Answer: Newton's laws of motion relate an object's motion to the forces acting on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.
What is the history of Newton's law of motion?
Newton developed his laws of motion in 1666, when he was only 23 years old. In 1687, he presented the laws in his seminal work "Principia Mathematica Philosophiae Naturalis,” in which he explained how outside forces affect the movement of objects.
Legend has it that Isaac Newton formulated gravitational theory in 1665 or 1666 after watching an apple fall and asking why the apple fell straight down, rather than sideways or even upward.
Isaac Newton's first law of physics says that an object in motion will stay in motion with the same amount of speed and in the same direction unless intervened by an unbalanced force. And that's exactly what happens with an automobile accident. Passengers continue to move unless stopped by a seat, dashboard, etc.
Isaac Newton is widely known for his published work Philosophiae Naturalis Principia Mathematica (1687), commonly known as the Principia. His laws of motion first appeared in this work. It is one of the most important single works in the history of modern science.
A ball rolling down a hill will continue to roll unless friction or another force stops it. If pulled quickly, a tablecloth can be removed from underneath of dishes. The dishes have the tendency to remain still as long as the friction from the movement of the tablecloth is not too great. Shaking a bottle of ketchup.
Early Life of Newton: A Difficult Childhood
Newton's father died three months before he was born. His mother remarried a minister when he was just three years old. The abandoned young Newton grew up with his grandmother until the age of 11. In 1653, Newton's mother returned for the first time after his stepfather died.
Sir Isaac Newton contributed significantly to the field of science over his lifetime. He invented calculus (opens in new tab) and provided a clear understanding of optics. But his most significant work had to do with forces, and specifically with the development of a universal law of gravitation and his laws of motion.
The first law of motion is sometimes also known as the law of inertia. There are two conditions on which the 1st law of motion is dependent: Objects at rest: When an object is at rest, velocity (v = 0) and acceleration (a = 0) are zero. Therefore, the object continues to be at rest.

He attended Free Grammar school. Though Newton did not excel in school, he did earn the opportunity to attend Trinity College Cambridge where he wanted to study law. His mother refused to pay for his education so while at college he worked as a servant to pay his way.
These laws tell us exactly how things move or sit still, like why you don't float out of bed or fall through the floor of your house. Newton's laws control how cars work, how water flows, how buildings don't fall down, and basically how everything around us moves.
Newton's second law is perhaps the most important physical law in mechanics. It says that the acceleration of an object is proportional to the net force applied to it and inversely proportional to the mass (reflecting inertia).
It is called the law of inertia because it tells that every material body has a property by virtue of which it resists the change in its state of rest or in its state of motion. This property is called inertia.
