Does the kinetic energy of a car change more when its speed goes from 40 kph to 60 kph or when its goes from 80 kph to 100 kph.​

Sagot :

Answer:

The following equation is used to represent the kinetic energy (KE) of an object. This equation reveals that the kinetic energy of an object is directly proportional to the square of its speed. That means that for a twofold increase in speed, the kinetic energy will increase by a factor of four.
