In order for work to take place, there is an amount of energy that has to be used. Work can either change the kinetic energy or change the potential energy. Do you understand the connection between work and energy? Test how well you understood the topic by taking up the quiz below. All the best and keep a lookout for more tests on the topic.
Force x Distance
Distance/Force
Force/Distance
Work is the what you get when a force acts over a certain distance. Therefore, without distance or force there would be no work.
Work and Distance are related because force is acted over a long distance.
Without work you do not have force.

Energy is the ability to do work or make work, and without it work not is done.
Energy causes a change, and work is needed for energy to happen.
Energy is the ability to do work or cause a change, and work is the transfer of energy.

Kinetic energy is the energy of motion, and potential energy is stored energy
Potential energy is the energy of weight, and kinetic energy is the energy of nuclear atoms.
Potential energy is the energy of speed, and kinetic energy is the stored energy.
Gravielastic energy, and Joules
Gravitational potential energy which is dependent on the height of the object.
Nucleus potential energy, depending on the amount of nuclear power.
GPE= 1/2 Mass X Velocity 10kg x 54m/s = 540 540/2= 270
GPE= M x G x H 5kg x 10x 2m = 100 Joules
GPE= M x G x H 5kg x 10x 2m = 100 Watts
GPE is potential energy that's dependent on height, EPE is energy associated with objects that can be stretched or compressed
GPE is potential energy dependent on weight only, and EPE is the potential energy only found in rubber bands.
GPE and EPE are the same, but are not written the same way.
