These questiоns must be cоmpleted befоre continuing to the second pаrt of the test contаining the lаst 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 first law of motion. b) Describe how Newton's second law connects the motion calculations that we did in Unit 1 to the dynamics concepts that we are looking at in Unit 2. c) How does a person jumping up into the air demonstrate Newton's third 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?
