How does the kinetic energy of a body change if its momentum is halved?

Since momentum is proportional to the velocity, half the momentum means half the velocity (and therefore half the speed). And since kinetic energy is proportional to the SQUARE of the speed, half the speed means 1/4 the kinetic energy.


What happens to the kinetic energy of a body if its speed is reduced to half?

If the speed of the body is reduced to half, its kinetic energy would decrease by a factor of four. This is because kinetic energy is directly proportional to the square of the velocity of the object. So, reducing the speed by half results in the kinetic energy being reduced by a factor of four.

The kinetic energyof an object is equal to one half it's mass multiplied by its speed?

Yes, that is correct. The kinetic energy of an object is equal to 0.5 times its mass times the square of its speed. This formula is derived from the classical physics definition of kinetic energy, which represents the energy an object possesses due to its motion.


What factors effect potential and kinetic energy?

Use the formula for kinetic energy: KE = (1/2) mv2 (one-half times the mass times speed squared). Clearly, the amount of kinetic energy depends both on the mass and on the speed of the object.


What is the formula in finding energy if the givens are mass and speed?

For a mass,m, moving at speed, v, the kinetic energy is E = 1/2 mv^2 ( one-half mass times speed squared)
