Pearson Ch. 1 Sec. 3 Energy Transformations

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as converting mechanical energy into electrical energy.

Front

What are the main types of energy?

Back

The main types of energy include mechanical, electrical, thermal, chemical, and radiant energy.

Front

What is mechanical energy?

Back

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

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons through a conductor.

Front

What is radiant energy?

Back

Radiant energy is the energy of electromagnetic waves, such as light.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter, related to the motion of particles.

Front

What is chemical energy?

Back

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

Front

How does a hydroelectric dam work?

Back

A hydroelectric dam converts the potential energy of falling water into mechanical energy, which then generates electrical energy.

Front

What happens to energy in a microwave oven?

Back

In a microwave oven, electrical energy is transformed into thermal energy to heat food.

Front

What is the energy transformation in photosynthesis?

Back

In photosynthesis, radiant energy from the sun is transformed into chemical energy in the form of glucose.
