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 has the potential to do work when released.

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 potential energy calculated?

Back

Potential energy (PE) can be calculated using the formula: PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

How is kinetic energy calculated?

Back

Kinetic energy (KE) can be calculated using the formula: KE = 1/2 mv², where m is mass and v is 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 and potential energy in a roller coaster?

Back

In a roller coaster, potential energy is highest at the top of the hills, and kinetic energy is highest at the bottom of the hills.

Front

What is an example of potential energy in everyday life?

Back

A drawn bow has potential energy due to the tension in the string, which can be released to shoot an arrow.

Front

What is an example of kinetic energy in everyday life?

Back

A moving car has kinetic energy due to its mass and speed.

Front

What factors affect kinetic energy?

Back

Kinetic energy is affected by the mass of the object and the square of its velocity.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object has due to its height above the ground, influenced by gravity.
