How much kinetic energy an object has depends on two factors: the mass of the object, and the speed of the object. We can analyze data to determine how kinetic energy depends on these two factors separately. If we keep the object's speed constant and increase its mass, the object's kinetic energy increases in a linear pattern. If we keep the object's mass constant and increase its speed, the object's kinetic energy increases in a nonlinear pattern.
