AV 8th Grade Semester Review

Front

What describes the motion of an object when its speed does not change?

Back

The object's speed is constant.

Front

At which point is potential energy greatest in a gravitational field?

Back

At the highest point of the object's position.

Front

When a pendulum swings, where is potential energy at its maximum?

Back

At the highest point of the swing.

Front

What two factors does gravitational potential energy depend on?

Back

Height and mass of the object.

Front

What is a conductor?

Back

A material that allows electricity to flow through it easily.

Front

What is an insulator?

Back

A material that does not allow electricity to flow through it easily.

Front

What happens to potential energy as an object is lifted higher?

Back

The potential energy increases.

Front

What is kinetic energy?

Back

The energy of an object due to its motion.

Front

How does mass affect kinetic energy?

Back

Kinetic energy increases with mass if speed is constant.

Front

What is the formula for gravitational potential energy?

Back

Potential Energy = mass × gravity × height.
