Kinetic&Potential Energy

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It is the energy that has the potential to be converted into kinetic energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass of the object and the speed at which it is moving.

Front

How is kinetic energy calculated?

Back

Kinetic energy (KE) is calculated using the formula: KE = 1/2 mv², where m is the mass of the object and v is its velocity.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases, assuming no energy is lost to air resistance.

Front

What is the relationship between kinetic energy and speed?

Back

Kinetic energy increases with the square of the speed. If the speed doubles, the kinetic energy increases by a factor of four.

Front

What type of energy does a stretched rubber band have?

Back

A stretched rubber band has potential energy due to its position and the tension in the material.

Front

When is potential energy at its maximum?

Back

Potential energy is at its maximum when an object is at its highest point relative to the ground.

Front

What is an example of kinetic energy in everyday life?

Back

An example of kinetic energy is a moving car, a running person, or a flowing river.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object has due to its height above the ground, calculated as PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

How does mass affect kinetic energy?

Back

The greater the mass of an object, the greater its kinetic energy will be at a given speed.
