Question

Kinetic energy of moving object is 100 Joule.If its speed is doubled than its kinetic energy will become ​

Answer 1

Answer:

when it's speed is doubled then it's kinetic energy will become 4 times

Answer 2

We can calculate the work done against gravity in moving a body of mass  (m) by a height (h) as, Work done in lifting a body = (Weight of body) (Vertical distance)

So, W = (m) (g) (h)
