Question

If the velocity of an object doubles, it's kinetic energy ?​

Answer 1

Explanation:

Kinetic energy depends on the velocity of the object squared. This means that when the velocity of an object doubles, its kinetic energy quadruples.

Answer 2

Answer:

The change in the kinetic energy of the object as the speed changes is proportional to the square of the factor by which the speed changes. If the speed of the object becomes double, its kinetic energy changes to four times the initial kinetic energy.If v becomes 2v, thenKE = ½m(2v)2= 4—½mv2= 4 times initial KE
