Energy and Engineering Review

Front

What is energy?

Back

Energy is the ability to do work or cause change. It exists in various forms, such as kinetic, potential, thermal, electrical, and chemical.

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 a circuit?

Back

A circuit is a closed loop that allows electricity to flow, providing a path for electrical current.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit where there are multiple paths for the current to flow. If one path is broken, the current can still flow through other paths.

Front

What is a series circuit?

Back

A series circuit is a type of electrical circuit where components are connected end-to-end, so the current flows through each component in turn.

What happens when you cut a wire in a parallel circuit?

Back

Cutting one wire in a parallel circuit does not stop the flow of electricity to other components; they can still operate.

Front

What is energy transformation?

Back

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

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 electrical energy?

Back

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

What is the role of a kettle in making tea?

Back

A kettle heats water using electrical energy, transforming it into thermal energy to boil the water for tea.
