What happens to the motion of an object when a force is applied?

Back

The object will accelerate in the direction of the applied force.

How can you reduce friction between two surfaces?

Back

You can reduce friction by using lubricants, smoothing surfaces, or using wheels.

Front

What is the difference between static and kinetic friction?

Back

Static friction acts on objects at rest, while kinetic friction acts on moving objects.

Front

What is an example of a situation where friction is beneficial?

Back

Friction is beneficial when walking, as it prevents slipping.
