Potential and Kinetic Energy for Kids | #aumsum #kids #education #science #learn
Energy can neither be created nor it can be destroyed. Energy can only be converted from one form to another. The unit of energy is joules. Energy can broadly ...
Answer
the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body when decelerating from its current speed to a state of rest.
In classical mechanics, the kinetic energy of a point object (an object so small that its mass can be assumed to exist at one point), or a non-rotating rigid body depends on the mass of the body as well as its speed. The kinetic energy is equal to 1/2 the product of the mass and the square of the speed. In formula form:
Ek = 1/2 mv2. Ek = Kinetic energy. m = mass.
