Kinetic energy is the energy of motion. The formula for kinetic energy is KE = 1/2mv2, where m is mass in kg and v is velocity in m/s. The formula indicates that KE is directly proportional to half the mass and velocity squared of an object in motion.
kinetic energy is defined as the energy possessed by a body by virtue of its MOTION Formula ;Ek=0.5xmassx(velocity)to the square
that is kinetic energy
If the speed of an object doubles, its kinetic energy quadruples. This is because velocity is squared in the formula for kinetic energy.
When you have kinetic energy, you must have a mass and a velocity since kinetic energy is half the product of the mass and the square of the velocity.
kinetic energy+potential energy=total energy
The formula for kinetic energy is KE = 1/2(mass)(velocity squared)
The formula for kinetic energy is KE = 1/2mv2, where m is mass in kg and v is velocity in m/s.
Mass of a body and its speed are needed to calculate kinetic energy. Kinetic energy of an object = mv2/2 This formula is useful only when object's speed is much less than speed of light.
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.
Kinetic energy = (1/2)mv^2 Kinetic energy =199295.1 J
Kinetic energy is 0.45 joules using the formula Ek = ½ x mv2
