Back

Friction is the resistance that one surface or object encounters when moving over another.

Front

Back

A pendulum is a weight hung from a fixed point that swings back and forth.

Front

What is viscosity?

Back

Viscosity is a measure of a fluid's resistance to flow.

Front

How does friction affect motion?

Back

Friction slows down the motion of objects.

Front

What is the effect of increasing the length of a pendulum?

Back

Increasing the length of a pendulum generally makes it swing slower.

Front

What is the relationship between mass and motion?

Back

Heavier objects may require more force to move, but they also have more momentum.
