Potential energy is the energy that exists by virtue of the relative positions (configurations) of the objects within a physical system. When the book hits the floor this kinetic energy is converted into heat and sound by the impact.
48. A ball has 100 J of potential energy when it is on a shelf. Explain what happens to the potential energy and the kinetic energy as the ball falls, and find the amount of kinetic energy the ball has at the instant it hits the floor. As the ball is falling, its potential energy is changing to kinetic energy.
The total energy of a system is the sum of kinetic and gravitational potential energy, and this total energy is conserved in orbital motion. Objects must have a minimum velocity, the escape velocity, to leave a planet and not return.
There many examples of potential and kinetic energy. Potential energy(P E ) + kinetic energy(K E) = mechanical energy. So if P E decreases then K E should increase and vice versa and mechanical energy of a system remains constant. Eg. : Bow and arrow : when we pull the arrow potential energy gets stored in it and when we release it P E changes to KE

Then make up two more and identify each as potential or kinetic in the same way. 1. The energy in a battery Using the battery to power a camera 2.
Potential Energy is based on mass, gravity, and height. Environment impacts Kinetic Energy and is relative to the environment : Potential Energy, on the other hand, is not influenced by environment. Kinetic Energy is already moving and is not at rest. Potential Energy is purely based on the position of the object and also the condition of the object.

ASSUMPTION: assume there is no friction and that all the potential energy you calculated in question 1 is transformed into kinetic energy – PE = KE. Use the following equation. KE= ½ m v2 You want to calculate v maximum speed v = [KE/ ½ m]½ This means divide the KE by half the mass and then take the square root.
Potential energy is that energy which an object has because of its position. It is called potential energy because it has the potential to be converted into other forms of energy, such as kinetic energy. Definition: Potential energy is energy that is stored in a system because of its position or chemistry. Potential Energy
Potential energy is the energy that has the energy in the stored form and this energy is based on its position. On the other hand, kinetic energy Energy can be described as the ability to do a certain task. Energy can be broadly categorized into two types of energies - Potential and Kinetic Energy.
