Newton’s First Law

Newton’s first law is the resistance to the change in motion. Meaning that if an object is at rest, it will continue to stay at rest. This also applies to if an object is in motion, it will continue to move the same direction and a constant speed. In the first video, I demonstrated Newton’s first law by rolling a ball. In the beginning, the ball was at rest but afterwards, a force was acted upon it and caused the ball to begin rolling and it will continue to roll as long as there is nothing that will stop the ball. You should take into consideration is the friction between the object and the ground because it will cause the ball to slow down and begin stopping to a rest.

Newton’s Second Law:

This is when if an unbalanced force acts upon an object and it will start to accelerate. Is based on the unbalanced forces and how when you apply the same amount of forces upon two different objects with different masses, they will both accelerate but at different rates. In the video, you can see that I have two different sized balls with different masses. These two balls were pushed and they both began to accelerate but at different speeds because of the difference in size and mass. Since the basketball has a higher mass and size in the foam ball, it has more friction with the ground which means that it will slow down quickly and it will need a greater applied force compared to the foam ball. However, the amount of force that was applied to each of the balls was different which cause the basketball to accelerate more than the foam ball.

Newton’s Third Law

Newton’s third law states that for every action there is an equal and opposite reaction towards it. For example, if the object is exerting a force to the left than the opposing force will counteract that and exert and an equal amount of force to the right. In the video, I took the foam ball and dropped it to the ground causing it to bound up and down a few times. When the ball was dropped, the force of the ball exerted a force on to the floor that was equal to the magnitude force that exerts on to the ball. Some things you want to consider is the shape of the ball. If the shape of the ball is distorted in some way, it may affect the way and the direction the bounces of the ball.
