inertia and car accidents Essays -- essays research papers
Exp # 1 Title: Inertia and Car accidents. Aim: To find out how inertia plays a part in accidents. Materials: 1.Ã Ã Ã Ã Ã Wooden ramp, approx 1.5m long and 30cm wide. 2.Ã Ã Ã Ã Ã Bricks or wooden blocks 3.Ã Ã Ã Ã Ã 2 dynamics, trolleys or toy cars 4.Ã Ã Ã Ã Ã Plasticine 5.Ã Ã Ã Ã Ã metre rule Method: 1.Ã Ã Ã Ã Ã Two plasticine dummies weighing 20g each were made and placed on the trolleys. 2.Ã Ã Ã Ã Ã Trolley B was placed 30-40cm in front of the ramp. 3.Ã Ã Ã Ã Ã Trolley A was placed 100cm from the end of the ramp. Directly in line with the other trolley. 4.Ã Ã Ã Ã Ã Trolley A was released and was let to collide into Trolley B, observations were made on what happened to the dummies. 5.Ã Ã Ã Ã Ã The experiment was repeated twice making sure everything was in the same place. Results: Refer to table 1. Questions: 1.Ã Ã Ã Ã Ã 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.Ã Ã Ã Ã Ã The conclusion I have drawn from the evidence suggests that the steeper the gradient, the greater the impact.
