Back

Friction is a force that opposes the motion of an object, caused by the contact between surfaces.

Front

What is an example of friction?

Back

Wind blowing against you as you walk is an example of friction.

Front

How does friction affect movement?

Back

The greater the friction, the more force needed to move an object.

Front

What is mass?

Back

Mass is the amount of matter in an object, which affects how much force is needed to move it.

Front

What happens to objects with greater mass?

Back

Objects with greater mass require more force to put in motion.

Front

What happens to objects with less mass?

Back

Objects with less mass require less force to put in motion.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.
