Energy and Engineering Review

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object. It is the energy associated with the motion and position of an object.

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons. It is used to power devices and appliances.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of particles in an object.

Front

What is energy transformation?

Back

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

Front

What happens when you plug in an electrical device?

Back

When you plug in an electrical device, electrical energy flows from the outlet to the device, allowing it to operate.

Front

What is the role of a catapult in experiments?

Back

A catapult is used to launch objects and test hypotheses about motion, distance, and energy.

Front

What is the purpose of a measuring tape in experiments?

Back

A measuring tape is used to measure distances accurately, which is important for testing hypotheses and recording results.

Front

What is refraction of light?

Back

Refraction of light is the bending of light as it passes from one medium to another, such as from air to water.

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a raised object has gravitational potential energy.
