Kinetic energy calculation examplesĮxample 1: A car weighs 2200kg (2.2 tonnes) and is moving with a velocity of 40 km/h. In which "KE" is kinetic energy and m is mass. Solving for mass requires a simple reordering of the equation:Īlternatively, one can solve for velocity and calculate it using the formula: ![]() If the object's speed is larger than a couple of percentages of the speed of light in vacuum it is a poor approximation according to relativistic mechanics. The KE formula and the equations below are valid in classical mechanics and for non-rotating rigid point objects (the object's mass is assumed to exist at a single point). It should be noted that velocity has exponential impact on energy, whereas mass has a linear impact, which has implication for ways to generate energy, such as in increasing one's punching power. The formula also shows that a body with a larger mass will have a larger kinetic energy at a certain velocity. A body with a given mass has a higher kinetic energy if it has a higher velocity, and vice versa. This equation is used in coding this online kinetic energy calculator and it shows the relationship between mass and energy is mediated through velocity. ![]() In physics, the formula for kinetic energy ( KE) expressed in terms of the body's velocity (speed) ( v) and its mass ( m) is the equation: When the output of the tool is mass or velocity it is in both standard metric units and imperial ones, with the units automatically being adjusted depending on how big or small the resulting value is. The output of the tool if calculating for kinetic energy is in Joules (J, kJ, MJ), Watt-hours (Wh, kWh), calories (Cal, kCal) and foot-pounds (ft-lbs). When solving for mass you need to know velocity and kinetic energy, while when solving for velocity you need to know the object's mass and kinetic energy. The respective input fields will be hidden or displayed upon selecting what you want to use the calculator for. The KE calculator can also be used to solve for any of the other values: mass and velocity. Its acceleration does not matter since the energy is calculated at a particular moment of time. To calculate the kinetic energy you need to know only the body's mass and velocity. It can also be used to calculate the energy of different kinds of projectiles: bullets, arrows, kinetic shells. For example, it can be used to calculate the kinetic energy of a person, vehicle (car, truck, train), plane, football, as well as for falling bodies that crash into the ground. ![]() This kinetic energy calculator is useful for estimating the energy a body acquires through movement of any kind.
