Energy Transformations

Front

What type of energy is food energy stored in your muscles?

Back

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

Front

At which position does a roller coaster cart have the most gravitational potential energy?

Back

Position W has the most gravitational potential energy because it is at the highest point.

Front

What are the energy transformations that occur when a pencil sharpener is plugged in?

Back

Electrical energy transforms into mechanical energy, which then transforms into sound energy.

Front

What types of energy does a television transform electrical energy into?

Back

A television transforms electrical energy into light, thermal, and sound energy.

Front

What is the sequence of energy transformations when a flashlight is turned on?

Back

The sequence is chemical energy → electrical energy → light energy.

Front

Define gravitational potential energy.

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, typically related to its height.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object.

Front

Explain the concept of energy transformation.

Back

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

Front

What is the difference between kinetic and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on an object's position.

Front

What type of energy is associated with the motion of particles in an object?

Back

Thermal energy is associated with the motion of particles in an object.
