Question

What is kinetic energy? give an example also tell do black holes can have the energy if yes then how?​please tell fast

Answer 1

1) the energy which an object has because of its motion is called kinetic energy

2) the kinetic energy gained by an object due to its motion is given by

K.E.= half mv 2

3) Kinetic energy is indipendent of height of an object but it depends on velocity of an object. i.e at ground level (h=0) K.E.= 0 but for V=0,K.E.=0

E.g. Moving water front tank to the tap.
