## How is the total energy related to the kinetic and potential energy?

The total amount of mechanical energy is merely the sum of the potential energy and the kinetic energy. This sum is simply referred to as the total mechanical energy (abbreviated TME).

What is the relationship between kinetic and potential energy when total energy stays the same in a system?

KEi + PEi = KEf + PEf That is, the sum of kinetic and potential energies is unchanging. While energy can be transformed from kinetic energy into potential energy, the total amount remains the same – mechanical energy is conserved.

Which best explain the relationship between potential and kinetic energy?

The main difference between potential and kinetic energy is that one is the energy of what can be and one is the energy of what is. In other words, potential energy is stationary, with stored energy to be released; kinetic energy is energy in motion, actively using energy for movement.

### What is the relationship between potential and kinetic energy and speed?

Potential energy is position relative. In other words, it changes depending on an object’s height or distance and the mass of the object. Kinetic energy changes depending on an object’s speed and its mass. If we think about a waterfall, some still water at the top of the waterfall has potential energy.

Are potential energy and kinetic energy inversely related?

Answer. Answer: As the height increases, there is an increase in the gravitational potential energy and a decrease in the kinetic energy . The kinetic energy is inversely proportional to the potential energy.

What is the relationship of kinetic energy and potential energy as the ball falls?

As the ball falls towards the ground, its gravitational potential energy is transformed into kinetic energy. The kinetic energy of the ball will continue increasing as the ball gains momentum, until it finally collides with a surface. When the ball collides, the kinetic energy is transformed into other forms of energy.

#### Is kinetic energy always equal to potential energy?

In all physical processes taking place in closed systems, the amount of change in kinetic energy is equal to the amount of change in potential energy. If the kinetic energy increases, the potential energy decreases, and vice-versa.

Are potential and kinetic energy inversely related?

What is difference between kinetic energy and potential energy?

When an object is at rest, the body is said to possess potential energy. In another case, when the object is in motion, then it is said to possess kinetic energy. Potential energy tends to affect the object within the environment if and only when it gets transformed to other kinds of energy.

## Why are kinetic and potential energy equal?

By definition, the change in Potential Energy is equivalent to the change in Kinetic Energy. The initial KE of the object is 0, because it is at rest. Hence the final Kinetic Energy is equal to the change in KE.

Are kinetic and potential energy inversely proportional?
