Learning goal 1: Select all of the scenarios below that describe something accelerating. A pen knocked off a deskAn ice skater gliding in a straight line, gently slowing downA statue, unmoving, in the parkA skydiver at terminal velocity – when air resistance stops them going any fasterA car turning a corner

An object moves in a circular path at a constant speed. Which of the following is true? A. The car’s acceleration is zero because it has a constant speed B. The car’s acceleration is not zero and causes the car to slow down C. The car’s acceleration is not zero and causes the car to speed up D. The car’s acceleration is not zero and causes the change in the direction of the car’s velocity E. None from the above
