What is the force that one surface exerts on another surface when two objects rub against each other?

Back

Friction.

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

How does friction affect motion?

Back

Friction opposes the motion of objects, slowing them down or preventing them from moving.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.

Front

What is inertia?

Back

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