IQWST PS2 Lessons 1-4

Front

What type of energy increases when an archer bends a bow?

Back

Elastic energy increases in the bow.

Front

What type of energy do apples hanging on a tree have?

Back

Gravitational energy.

Front

Where is maximum potential energy on a roller coaster?

Back

At the top of a big hill.

Front

What kind of energy is in a waving hand?

Back

Kinetic energy.

Front

What kind of energy is in a moving skateboard?

Back

Kinetic energy.

Front

Define potential energy.

Back

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

Front

Define kinetic energy.

Back

Kinetic energy is the energy of an object in 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 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 the relationship between kinetic and potential energy in a roller coaster?

Back

As the roller coaster climbs, potential energy increases and kinetic energy decreases; as it descends, potential energy decreases and kinetic energy increases.
