Question

define kinetic energy of a body what happened to the kinetic energy of a moving body when its speed is doubled​

Answer 1

The kinetic energy[K.E] of an object is defined as the energy possessed by the object by the virtue of its motion.

=>Given by: E = ½mv² •SI unit: joule(J)

• If the velocity of an object is doubled, then by the formula ½mv², the kinetic energy of the object act becomes 4 times...
