In this part we are going to discuss about the Newton’s three laws of motion.
As we all know Motion is a kind of state in which some distance is being covered with respect to the time that possesses some speed. We have a well-flourished generation that believes in science and technology which is purely adapted from somewhere who is none other then but our respective and intelligent scientists who did a lot of inventions to make our life easy and fruitful.
Laws of motion, also known as Newton’s three Laws of Motion.
- First law motion:
- Every object persists in the same state as it is, either at rest or motion until an external force is applied to it.
- It is also known as the Law of Inertia because this shows the property of massive change in the states of motion.
- It was discovered by Galileo.
- It simply means that an object can’t start, stop or change direction by themselves, it needs some external force to do that so.
- The second law of motion:
- Force equals mass times acceleration (F = ma), where “F” is a force, “m” is mass and “a” is acceleration.
- It describes the reaction of the massive body when external for is applied to it which can add velocity, slow speed, and change direction of the stationary body.
- SI unit office in Newton.
- Third Law of motion:
- Every action has an equal and opposite reaction.
- When an object pushes a second object at a point of contact with some applied force then, there must be the equal and opposite amount of force to the first one from the second object that can cancel the applied force.
- For example – Throwing football on the ground gives the same amount of force to the ground again which results in the bouncing back of the football.
