Energy Review

Front

What is the energy of motion called?

Back

Kinetic energy

Front

As a pendulum swings from its highest to lowest position, what happens to its potential and kinetic energy?

Back

The potential energy decreases while the kinetic energy increases.

Front

What is the energy transformation when electrical energy is converted to mechanical, thermal, and sound energy?

Back

Electrical to mechanical to thermal to sound.

Front

How does the speed of an object affect its kinetic energy?

Back

The faster an object moves, the more kinetic energy it has.

Front

Which device changes electrical energy into light and sound energy?

Back

Alarm clock.

Front

What type of energy is stored in an object due to its position?

Back

Potential energy.

Front

What is the formula for calculating kinetic energy?

Back

KE = 1/2 mv² (where m is mass and v is velocity).

Front

What happens to the total mechanical energy in a closed system?

Back

It remains constant (Law of Conservation of Energy).

Front

What is an example of energy transformation in a battery-powered toy?

Back

Chemical energy in the battery is transformed into mechanical energy.

Front

What type of energy is associated with the position of an object in a gravitational field?

Back

Gravitational potential energy.
