Newton’s First Law
Newton’s First Law of Motion tells how an object moves. The first law states that an object in motion stays in motion and an object at rest stays at rest unless acted upon by an outside force. (“Laws of Motion”). This would mean that another force would have to act on an object to make it change the motion, or lack of, that it is experiencing. For example, gravity pulls an object downwards, which would slow it and, eventually, stop it. Friction would also slow down an object, possibly until it stopped too. There are many occurrences just in daily life that you can look at to see examples …show more content…
This law states that force is equal to mass times acceleration.(“Newton’s Laws of Motion”). If a large object and a small object have the same force applied to them, then the smaller object would accelerate more. This is because the smaller object had less mass, and less mass requires less force to be accelerated. Newton’s Second Law can be seen in many aspects of daily life.
One example of Newton’s Second Law is if you are moving something very heavy. For this we are just going to use a fridge as an example. If you are moving a fridge, then you probably noticed that it requires a lot of force to move. Someone moving something smaller, like an empty cabinet, will be having a much easier time pushing theirs. This is because a fridge would have more mass than an empty cabinet, so it would require much more force to push. The force that you apply on the fridge would spread out among its large mass, while the force that would be applied on the cabinet would be all directed towards moving …show more content…
If you lift a light object, it lifts up fast and requires little force, but a heavy object requires much more and would lift a lot slower than the light object. This is because objects with more mass require more force to get them to move. The light object would also have less resistance to moving, so it would be quicker to change its course of motion.
Newton’s Third Law
Newton’s Third Law of Motion tells how and why an object is moving. “Newton 's third law states that for every action there is an equal and opposite reaction” (“Laws of Motion”). This means that for every force that is exerted, and equal force is exerted in the opposite direction. The first force is known as the action force, and the equal and opposite force that happens because of it is known as the reaction force. No force can happen on it’s own, every force has another force that results because of it.
One example of Newton’s Third Law is seen when you push on a wall. If you push on a wall, then you do not fall through it. The wall stays up. However much you push on the wall, the wall pushes back on you to keep you from falling through. You pushing on the wall is the action force, and the wall pushing back on you is the reaction force. If the wall did not push back, then you would end up falling through the
