A car has kinetic energy ‘Eₖ’. By what factor would its kinetic energy change if its velocity is doubled?
Kinetic energy is proportional to the square of the velocity of an object. The formula for kinetic energy is given by Ek=1/2mv2, where m is the mass and v is the velocity. If the velocity of the car is doubled, the kinetic energy will increase by a factor of four. This is because (2v)2=4v2, so … Read more
