Which statements explain the relationship between mass, velocity and kinetic energy? Consider the equation to calculate kinetic energy: KE = ½mv2 1. Kinetic energy increases if either the mass or the velocity of the object increases or if both increase.

2. Kinetic energy decreases if either the mass or the velocity of the object increases or if both increase.

3. Kinetic energy decreases if either the mass or the velocity of the object decreases or if both decrease.

4. Kinetic energy increases if either the mass or the velocity of the object decreases or if both decrease
