Energy Transformations

Front

What is energy transformation?

Back

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

Front

What are the main types of energy?

Back

The main types of energy include kinetic, potential, thermal, chemical, electrical, and sound energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, which depends on its mass and velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state, such as gravitational potential energy.

How does a pencil sharpener transform energy?

Back

A pencil sharpener transforms electrical energy into mechanical energy to rotate the blades, which then produces sound energy.

Front

What energy transformation occurs in a flashlight?

Back

In a flashlight, electrical energy is transformed into thermal energy (heat) and light energy.

Front

What is the role of the Sun in energy transformations on Earth?

Back

The Sun provides light energy and heat energy, which are essential for processes like photosynthesis and climate.

Front

What is chemical energy?

Back

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

Front

How does a battery work in terms of energy transformation?

Back

A battery transforms chemical energy into electrical energy, which can then be converted into light energy in devices like flashlights.

Front

What is thermal energy?

Back

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