What is resistance to motion called?

Back

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

Front

Which pendulum will swing the fastest?

Back

The shortest pendulum will swing the fastest due to less distance to travel.

Front

What causes pendulums to form neat patterns?

Back

Back

Air reduces friction, allowing the puck to glide smoothly.

Front

What is produced by the friction of two surfaces rubbing against one another?

Front

What is a pendulum?

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

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion.
