Calculate kinetic energy given mass and velocity: Kinetic Energy KE equals 1/2 times mass m times velocity squared v2
Calculate mass given kinetic energy and velocity: Mass m equals 2 times kinetic energy KE divided by velocity squared v2
Calculate velocity given kinetic energy and mass: Velocity v equals the square root of kinetic energy KE divided by one half of the mass m
It describes how quickly or slowly an object moves from one place to another. The standard (SI) unit of speed is meters per second (m/s), but it can also be expressed in other units, such as kilometers per hour (km/h), miles per hour (mph), or feet per second (ft/s), depending on the context or the country's measurement system.
Sep 25, 2024 · 1. Write the equation. The formula for calculating kinetic energy (KE) is KE = 0.5 x mv2. Here m stands for mass, the measure of how much matter is in an object, and v stands for velocity of the object, or the rate at which the object changes its position.

To calculate the kinetic energy, first convert km/h to meters per second: 40km/h = 11.11 m/s. Using the first kinetic energy equation above, replace the values for m and v and get KE = 2200 · (11.11) 2 / 2 = 135775.3 Joules or 135.7753 kiloJoules. Example 2: A ball which weighs 500 grams has a kinetic energy of 500 J.
Energy in the kinetic energy store (Ek) = 0.5 x mass (m) x velocity² (v²) \(Ek = 0.5 \times m \times v²\) The unit of measurement for the amount of energy in the kinetic energy store is the ...
Standard gravity is, by definition, 31.17405 ft/s² (9.80665 m/s²), so if a human weighs 220 lb (about 100 kg), he is subjected to the gravitational force of about 7000 pdl (1000 N). Let's enter this value into window #3 of our calculator along with the mass of the Earth (1.317 × 10²⁵ lbs or 5.972 × 10²⁴ kg in scientific notation).
