Big Idea 10 and 11

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the energy that comes from the movement of atoms and molecules in a substance.

Front

What is light energy?

Back

Light energy is a form of energy that is visible to the human eye. It is produced by the vibrations of electrically charged particles.

Front

What happens when energy is applied to an object?

Back

When energy is applied to an object, it can cause the object to move, change shape, or change temperature.

Front

What is reflection of light?

Back

Reflection of light is when light bounces off a surface, such as a mirror, allowing us to see images.

Front

What is absorption of light?

Back

Absorption of light is when light is taken in by a material, converting it into other forms of energy, such as heat.

Front

What is energy transfer?

Back

Energy transfer is the process of energy moving from one object or system to another, such as when a person throws a ball.

Front

What is the role of friction in energy transfer?

Back

Friction is a force that opposes motion, converting kinetic energy into thermal energy, often causing objects to slow down.

Front

What is static electricity?

Back

Static electricity is the build-up of electric charge on the surface of objects, which can cause them to attract or repel each other.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a ball at the top of a hill has potential energy.
