Energy Transformations

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as from light energy to chemical energy.

Front

What is the primary energy transformation that occurs during photosynthesis?

Back

The primary energy transformation during photosynthesis is from light energy to chemical energy.

Front

Define chemical energy.

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like food and fuels.

Front

What happens to energy when a lion eats a zebra?

Back

The lion converts the chemical energy stored in the zebra into mechanical energy to run.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter, often referred to as heat.

Front

Explain the energy transformation that occurs when a battery powers a flashlight.

Back

The energy transformation is from chemical energy in the battery to electrical energy, which is then converted to light energy.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state, such as a skydiver at a height.

Front

Describe the energy transformation that occurs when a skydiver jumps from a helicopter.

Back

As the skydiver falls, they gain kinetic energy and lose potential energy.

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 is the relationship between kinetic energy and potential energy during free fall?

Back

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