Which of the following are true, regarding motion? Select all that are True. If the slope of a plot of position versus time is changing, the object is undergoing acceleration. If the slope of a plot of velocity versus time is constant, the object cannot be moving. If a feather and a lead ball are dropped from the same height at the same time in vacuum, they will hit the ground at the same time. When a ball thrown upward reaches its highest point, its acceleration is zero. If you travel at 70 mi/hr from Fargo to Minneapolis, MN, and then return to Fargo at the same speed, your average velocity for the trip is zero. If the slope of a plot of velocity versus time has a constant negative value, the object must be slowing down.
