Is there a relationship between mass and speed and computing kinetic energy Why?
Is there a relationship between mass and speed and computing kinetic energy Why? An object with less speed and more mass could potentially have the same Kinetic energy. The equation for Kinetic Energy is: KE = 1/2 mv2. Kinetic energy has a direct relationship with mass, meaning that as mass increases so does the Kinetic […]
