Question

if the speed of a car is increased four times the kinetic energy of the car increases or times of 4 x 16 X 8 x 20 X ​

Answer 1

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.

For example if the speed of the object becomes double, its kinetic energy changes to four times the initial kinetic energy.
