Forms of Energy Review

Front

A rollercoaster that reaches the top of a hill is an example of ____________ energy.

Back

Potential energy is the energy stored in an object due to its position or height.

Front

A pitcher is getting ready to throw a baseball. Before he throws the ball, it is an example of ____________ energy.

Back

Potential energy is the energy stored in an object due to its position or height.

Front

When a soccer ball is kicked, it is an example of ____________ energy.

Back

Kinetic energy is the energy of an object in motion.

Front

What is sound energy?

Back

Sound energy is an example of kinetic energy, because energy is carried through vibrating waves.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object that is in motion.

Front

Calculate the kinetic energy of a 1 kg tennis ball moving at 20 m/s.

Back

KE = 0.5 * mass * velocity^2 = 0.5 * 1 kg * (20 m/s)^2 = 200 J.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter, related to the motion of particles.
