KInetic and Potential Energy Modified

Front

What is kinetic energy?

Back

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

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state, 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.

Front

How does speed affect kinetic energy?

Back

The faster an object moves, the more kinetic energy it has, as kinetic energy is proportional to the square of its velocity.

Front

At what point is potential energy greatest in a falling object?

Back

Potential energy is greatest at the highest point of the object's path, before it begins to fall.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

What is the relationship between kinetic energy and mass?

Back

Kinetic energy is directly proportional to the mass of the object; increasing the mass increases the kinetic energy.

Front

What is the formula for calculating kinetic energy?

Back

The formula for calculating kinetic energy is KE = 1/2 mv².

Front

What is the formula for calculating potential energy?

Back

The formula for calculating gravitational potential energy is PE = mgh.

Front

What type of energy does a compressed spring have?

Back

A compressed spring has elastic potential energy, which is stored energy due to its deformation.

Front

What happens to the total mechanical energy in a closed system?

Back

In a closed system, the total mechanical energy (kinetic + potential) remains constant, assuming no external forces do work.
