How Does Friction Affect the Motion of Objects?

What role does friction play in the motion of objects?

A. It speeds up the objects. B. It stops the objects. C. It helps the objects maintain their speed. D. It slows down the objects.

Answer:

D. It slows down the objects.

Friction is a force that opposes the motion of objects when they are in contact with each other. When two surfaces rub against each other, friction converts the kinetic energy of the moving object into heat and sound energy, causing the object to slow down. This process is especially noticeable when a moving object comes to a stop or when you try to slide a heavy object along the ground. Friction also plays a crucial role in helping objects grip surfaces to prevent slipping.

In summary, friction affects the motion of objects by slowing them down and providing stability and traction. Understanding how friction works can help us predict how objects will move in various situations.
