PHYS220 Final 201730 Question 11 Which one of the following is not conclusive evidence of an interaction? A. Change of velocity, either change of direction or change of speed. B. Change of shape or configuration without change of velocity. Change of position without change of velocity. D. Change of identity without change of velocity. E. Change of temperature without change of velocity.
