If two objects with different masses are moving in the same direction and at the same speed, what will happen to the kinetic energy?

• Both objects will have the same kinetic energy because they are traveling at the same speed

• The object with less mass will have greater kinetic energy

• The object with greater mass will have greater kinetic energy

• We can’t tell which has greater kinetic energy from this information
