Transfer of Energy

Front

What is energy transfer?

Back

Energy transfer is the process of energy moving from one system or object to another, often resulting in a change in form.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object that is used to do work.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state, such as height above the ground.

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 sound energy?

Back

Sound energy is a form of energy produced by vibrating objects, which travels through air, water, or solids.

How is energy transformed in a gasoline-powered car?

Back

In a gasoline-powered car, chemical energy from gasoline is transformed into mechanical energy to move the car.

Front

What happens to energy when a nail is hammered?

Back

When a nail is hammered, mechanical energy is transferred to the nail, causing it to move and penetrate a surface.

Front

What is the role of a dam in energy transformation?

Back

A dam converts potential energy of stored water in a reservoir into electrical energy through turbines.

Front

At what point does an object have the greatest potential energy when thrown?

Back

An object has the greatest potential energy at its highest point during its flight.

Front

What is the relationship between mechanical energy and work?

Back

Mechanical energy is used to perform work, which is the transfer of energy through force applied over a distance.
