Energy Test 24/25

Front

What is electrical energy?

Back

Electrical energy is the energy that comes from the movement of electrons from one object to another.

Front

What type of energy transformation occurs when a hawk eats a mouse?

Back

The transformation is from chemical energy (from the mouse) to mechanical energy (used for flying).

Front

How does mass relate to kinetic energy?

Back

Kinetic energy increases with mass; a graph showing this relationship typically has a positive slope.

Front

What is the energy transformation when eating a peanut butter and jelly sandwich and then riding a bike?

Back

The transformation is from chemical energy (from the sandwich) to mechanical energy (used for biking).

Front

What happens when a crock pot is plugged in and turned on?

Back

The energy transformation is from electrical energy to thermal energy.

Front

Define kinetic energy.

Back

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

Front

Define potential energy.

Back

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

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter; it is the total kinetic energy of particles in an object.

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like food or fuel.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential and kinetic energy in an object that is used to do work.
