when objects speed doubles its kinetic energy​

Sagot :

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.

Answer:

Because kinetic energy is proportional to the square of the velocity, when velocity is doubled, kinetic energy is quadrupled.

Explanation:

Kinetic energy = 0.5 x mass x velocity (squared)

So for a 2 kg object moving 2 m/S

0.5 x 2 x 2 squared =0.5 x 2 x 4 =4

So now if we double the velocity to 4

0.5 x 2 x 4 squared = 0.5 x 2 x 16 = 16

Double the velocity and quadruple the kinetic energy
