Energy conversions-NGS 2

Front

What is energy conversion?

Back

Energy conversion is the process of changing energy from one form to another, such as from electrical energy to kinetic energy.

Front

What type of energy is associated with a rubber band?

Back

Elastic energy is the potential energy stored in an elastic object when it is stretched or compressed.

Front

What is the energy conversion that occurs when batteries are used in a flashlight?

Back

The energy conversion is from chemical energy (in the batteries) to light energy.

Front

What type of energy does a rock at the top of a cliff represent?

Back

Gravitational energy, which is the potential energy an object has due to its position in a gravitational field.

Front

What does the energy conversion Chemical → light indicate?

Back

It indicates that chemical energy is being transformed into light energy, as seen in devices like flashlights.

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 of an object due to its position or state, such as gravitational or elastic potential energy.

Front

Can energy be created or destroyed?

Back

No, according to the law of conservation of energy, energy cannot be created or destroyed, only transformed from one form to another.

Front

What is an example of mechanical energy?

Back

Mechanical energy is the sum of potential and kinetic energy in an object, such as a moving car.

Front

What is thermal energy?

Back

Thermal energy is the internal energy of an object due to the kinetic energy of its molecules, often perceived as heat.
