Front

What happens to the kinetic and gravitational energies of an ice cream cone when it is falling?

Back

The kinetic energy increases while the gravitational energy decreases.

Front

When an object emits a sound, it ____________ some of its energy to its surroundings.

Back

loses

Front

An object can stop because the energy is transferred to its surroundings. True or False?

Back

True

Front

What is kinetic energy?

Back

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

Front

What is gravitational energy?

Back

Gravitational energy is the potential energy held by an object because of its height above the ground.

Front

What is elastic energy?

Back

Elastic energy is the potential energy stored in an object when it is compressed or stretched.

Front

What is thermal energy?

Back

Thermal energy is the total energy of all the particles in an object due to their motion.

Front

What happens to energy when an object falls?

Back

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