so its the loss of potential energy which is equal to KE?
Potential energy is the energy possessed by an object due to its position or configuration, while kinetic energy is the energy possessed by an object due to its motion.
Work is the transfer of energy from one form to another, so when work is done on an object, its potential or kinetic energy can change. For example, pushing a swing increases its potential energy, and releasing it increases its kinetic energy.
Yes, an object can have both potential and kinetic energy at the same time. For example, a rollercoaster at the top of a hill has potential energy due to its height, but also has kinetic energy because it is in motion.
The equation for work (W) is W = F*d, where F is the force applied and d is the distance over which the force is applied. This equation also applies to changes in potential and kinetic energy, as the force applied can change an object's position (potential energy) or speed (kinetic energy).
In an ideal situation with no energy losses, work is indeed equal to the change in potential and kinetic energy. However, in real-world scenarios, there may be other factors such as friction or air resistance that can affect the amount of work done and the change in energy.
