The object doing the work loses energy, while the object on which the work is done gains energy. This illustrates the transfer of energy between objects.

These examples show that objects can acquire energy through different means (winding, pressing), enabling them to do work (moving, changing shape, exploding).
If a balloon is pressed too hard, it can explode, releasing the stored energy rapidly and producing a blasting sound.
The balloon changes shape when pressed but returns to its original shape when the force is withdrawn, demonstrating its elastic potential energy.
A fast-moving object has more kinetic energy compared to a slow-moving object of the same mass because kinetic energy is directly proportional to the square of the object’s velocity. This means that even a small increase in velocity results in ...
Work is the transfer of energy from one object to another or the conversion of energy from one form to another. In the examples, the cricket ball does work on the wicket by transferring its kinetic energy to it. Similarly, ...
When the hammer is raised, it has gravitational potential energy due to its height above the nail. As the hammer falls, this potential energy is converted into kinetic energy. When the hammer strikes the nail, the kinetic energy is transferred ...
An object raised to a certain height possesses gravitational potential energy. This energy is given by the formula: PE = mgh where m is the mass of the object, g is the acceleration due to gravity, and ℎ is the height above ...
Kinetic energy is the energy possessed by an object due to its motion. It is given by the formula: KE= 1/2mv² where m is the mass of the object and v is its velocity. In the example of the cricket ...
Tidal energy is harnessed by capturing the energy from the rise and fall of sea levels caused by the gravitational forces of the moon and the sun. This energy can be converted into electricity using tidal turbines or tidal barrages. ...
