Energy Transformations TEST

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as from chemical energy in food to mechanical energy in movement.

Front

What are the main forms of energy?

Back

The main forms of energy include kinetic, potential, thermal, chemical, electrical, and light energy.

Front

What happens to energy during a thunderstorm when lightning occurs?

Back

During a thunderstorm, energy transforms from electrical energy to light and thermal energy.

Front

How do plants transform energy from the Sun?

Back

Plants transform light energy from the Sun into chemical energy through the process of photosynthesis.

Front

What is the relationship between potential energy and height?

Back

As an object is lifted higher above the ground, its potential energy increases due to the increase in height.

Front

What energy transformation occurs when a person rubs their hands together?

Back

The energy transformation that occurs is from chemical energy (from food) to mechanical energy (movement) to thermal energy (heat).

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like food, which can be released during chemical reactions.

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.

Front

What happens to energy when a ball is thrown into the air?

Back

As the ball rises, kinetic energy is converted to potential energy; at the highest point, potential energy is maximized before falling back down.

Front

What is thermal energy?

Back

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