Kinetic and Potential Energy

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion, calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration, commonly associated with gravitational potential energy, calculated using the formula PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

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.

What is the relationship between kinetic energy and speed?

Back

Kinetic energy is proportional to the square of the speed; if the speed doubles, the kinetic energy increases by a factor of four.
