These questions must be completed before continuing to the second part of the test containing the last two questions. These three questions do not require you to do any hand writing or the use of scratch paper. Your attention should remain on the screen while answering these questions. Make sure that these questions are complete before moving on to Part 2. Question 1 (10 marks) a) Describe a situation that demonstrates Newton’s second law of motion. b) Describe an action and reaction force involved with pushing a box forward across the ground. c) What is inertia and how is it related to Newton’s first law of motion? Question 2 (10 marks) a) Describe how you could determine the net force for an object using a free body diagram. b) For objects that are sliding across the ground (on Earth), how does the force of gravity influence the force of friction that they are experiencing? Question 3 (10 marks) a) If an object is placed on a ramp and starts to slide down towards the bottom of the ramp, what force(s) determine it’s acceleration? b) Why would increasing the angle of a ramp increase the acceleration that an object that is sliding down the ramp experiences?
