 2) What is the rate of change of velocity called? Constant acceleration. Increasing acceleration. Decreasing acceleration. Zero acceleration.

 3) The product of mass and velocity is called_____ Force Momentum Torque Work

 4) Which of the following statements is false? F= ma F= m dv/dt F = dp/dt F =mda/dt

 5) Which of the following is correct for acceleration due to gravity at the equator on Earth? 9.6 9.8 9.7 9.5

 6) Consider two bodies having the same mass and falling from different heights. Which one should have the maximum velocity when reaching the ground (neglecting air resistance)? Highest massed object. Least massed object. Both will have the same velocity. One falling from highest height.
