inertia and car accidents Essays -- essays research papers

Exp 1Title Inertia and Car accidents.Aim To find egress how inertia plays a part in accidents.Materials 1.Wooden ramp, approx 1.5m long and 30cm wide.2.Bricks or wooden blocks3.2 dynamics, trolleys or toy cars4.Plasticine5.metre rule Method1. twain 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 end of the ramp. now in line with the other trolley.4.Trolley A was released and was let to collide into Trolley B, observations were made on what happened to the dummies.5.The experiment was repeated twice making real everything was in the same place.Results Refer to table 1.Questions1.What happened to the dummy on trolley A during the collision? Did it move 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 dummy fell further forward.2.The conclusion I have drawn from the evidence suggests that the steeper the gradient, the greater the impact.
