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‚  Wooden ramp, approx 1.5m long and 30cm wide. 2.  Ã‚  Ã‚  Ã‚  Ã‚  Bricks or wooden blocks 3.  Ã‚  Ã‚  Ã‚  Ã‚  2 dynamics, trolleys or toy cars 4.  Ã‚  Ã‚  Ã‚  Ã‚  Plasticine 5.  Ã‚  Ã‚  Ã‚  Ã‚  metre rule Method: 1.  Ã‚  Ã‚  Ã‚  Ã‚  Two plasticine dummies weighing 20g each were made and placed on the trolleys. 2.  Ã‚  Ã‚  Ã‚  Ã‚  Trolley B was placed 30-40cm in front of the ramp. 3.  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‚  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‚  The experiment was repeated twice making sure everything was in the same place. Results: Refer to table 1. Questions: 1.  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‚  The conclusion I have drawn from the evidence suggests that the steeper the gradient, the greater the impact.
