Work and Energy Basics

Front

What is Kinetic Energy?

Back

Kinetic energy is the energy of an object due to its motion. It depends on the mass and velocity of the object.

Front

What is Potential Energy?

Back

Potential energy is the energy stored in an object due to its position or configuration. It is often associated with gravitational energy.

Front

What is the formula for Kinetic Energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for Potential Energy?

Back

The formula for gravitational potential energy (PE) is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What is Work in physics?

Back

Work is done when a force causes an object to move. It is calculated as Work = Force x Distance.

Front

What is the unit of Work?

Back

The unit of work is the Joule (J), which is equivalent to one Newton meter.

Front

What is the Conservation of Energy?

Back

The Conservation of Energy theorem states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is Mechanical Energy?

Back

Mechanical energy is the sum of kinetic and potential energy in a system.

Front

What is the relationship between Work and Energy?

Back

Work done on an object results in a change in its energy. If work is done on an object, its energy increases.

Front

What is a Force?

Back

A force is a push or pull acting on an object, which can cause it to accelerate.
