This formula is valid only for low. Two vehicles of the same mass moving at different speed. Divide kinetic energy by the product.
The kinetic energy formula defines the relationship between the mass of an object and its velocity.
The kinetic energy formula defines the relationship between the mass of an object and its velocity. KE car - cars kinetic energy J- Joules v car - cars speed remember that v without an arrow means the length of the velocity vector which is speed. Ek is the energy of a mass m in motion v2. Kinetic energy calculator solving for velocity given energy and mass.
