What is the relationship between kinetic energy and potential energy of a falling object?
You now know that potential energy is position relative, and kinetic energy is motion relative. The primary relationship between the two is their ability to transform into each other. In other words, potential energy transforms into kinetic energy, and kinetic energy converts into potential energy, and then back again.
What is the relationship between gravitational energy and kinetic energy?
Kinetic energy is energy an object has because of its motion. A ball held in the air, for example, has gravitational potential energy. If released, as the ball moves faster and faster toward the ground, the force of gravity will transfer the potential energy to kinetic energy.
What is the mathematical relationship between kinetic and potential energy?
At a start, the potential energy = mgh and kinetic energy = zero because its velocity is zero. Total energy of the object = mgh. As it falls, its potential energy will change into kinetic energy. If v is the velocity of the object at a given instant, the kinetic energy = 1/2mv2.
What is the relation between kinetic energy potential energy and total energy?
Negative kinetic energy equals half the potential energy (−K = ½U). Potential energy equals twice the total energy (U = 2E). Total energy equals negative kinetic energy (E = −K). Twice the kinetic energy plus the potential energy equals zero (2K + U = 0).
What is the mathematical relationship between kinetic and potential energy and total mechanical 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 formula of kinetic energy and potential energy?
Difference Between Kinetic Energy and Potential Energy

How are potential and kinetic energy related mathematically?
Kinetic energy can be defined mathematically as KE=12mv2 KE = 1 2 mv 2 , where KE = kinetic energy, m = mass, and v = velocity. Figure 1. James Prescott Joule. Another frequently encountered energy is potential energy, a type of energy that is stored in matter and released during a chemical reaction.
