Exp 1Title Inertia and Car accidents.Aim To find out how inertia plays a part in accidents.Materials 1.Wooden ramp, approx 1.5m long and 30cm wide.2.Bricks or woody blocks3.2 dynamics, trolleys or toy cars4.Plasticine5.metre rule Method1. devil plasticine dummies weighing 20g each were made and placed on the trolleys.2.Trolley B was placed 30-40cm in front of the ramp.3.Trolley A was placed 100cm from the turn back of the ramp. Directly in line with the other trolley.4.Trolley A was released and was permit to collide into Trolley B, observations were made on what happened to the dummies.5.The experiment was repeated twice making sure everything was in the same place.Results Refer to table 1.Questions1.What happened to the green goddess on trolley A during the collision? Did it give notice during the collision? Did it move forward, backward, or stay in the same place?The Dummy on Trolley A fell forward during the collision, as the gradient increased, the the skinny fell furt her forward.2.The conclusion I have drawn from the secernate suggests that the steeper the gradient, the greater the impact.
