When an object is dropped from above the ground, work is done as the object is pulled to the ground. As the object is falling and work is done, the potential energy of the body is changed to kinetic energy
Potential energy is the type of energy possessed by a body due to its position. A stone on the ground does not have energy so long as it is lying… Read More »POTENTIAL AND KINETIC ENERGY
Work is the product of force and distance moved in a given direction and the quantity of workdone is always equal to the quantity of energy put in. In science,… Read More »CONCEPT OF WORK, ENERGY AND POWER
