Question

a boulder and a pebble are sitting on a cliff which has greater grvitational potential energy and why? a cheetah and a person are racing both has the same mass whifh has greater kinetic energy and why.​

Answer 1

since both boulder and pebble are at the same height from ground, the one with the greater mass would have more GPE. Cheetah has greater KE. as KE = 0.5mv^2 so since both person and cheetah have the same mass, cheetah would obviously have greater speed, v thus greater KE
