Question

the kinetic energy of an object mass m moving with the the velocity of 5 metre per second in 25 what will be the kinetic energy when its velocity is doubled​

Answer 1

Answer:

Kinetic energy is a scalar quantity and is calculated using equation E=(1/2)p.v [ vector] = (1/2)mv² [ where v is speed]. Both the terms are correct. Vectorially, v.v= v² , where v² is the square of the magnitude of v vector.
