= energy of movement
Kinetic Energy = 1/2 x mass, kg x speed(2) ... Ek = 1/2 x m x v(2)
Kinetic energy of something depends on mass and speed. The more it weighs and the faster it goes, the bigger its kinetic energy will be.
Kinetic energy transferred = work done
when a car moves, it has kinetic energy, to slow a car down, this kinetic energy needs to be converted into other types of energy. to stop a car, the kinetic energy has to be converted to heat energy as friction between wheels and brake pads causing the temperature of the brakes to increase.
1/2mv(2) = F x d
m = mass of car and passengers, kg v = speed of car, m/s F = max braking force, N d = braking distance, m
