Experiment #3: Collisions
... experiment of the PH1004 laboratory course is broken down into two parts. In part A, the aim is to assess the conservation of momentum and of kinetic energy for an elastic collision between a moving glider, which runs along a straight line on an air track, and a stationary glider. Momentum ...

... on the concrete side of this problem. Now, the awareness of the population is going more or less the right way so the government should concentrate on promoting new noticeable ideas such as the obligatory use of electrical or hybrid cars. Nevertheless, I must admit that the idea of ...
How much does the air pressure within a football matter?
... elastic. Elasticity enables an object to release energy that is received during a collision. This is called an elastic collision. When the ball is kicked, the gas within the ball compresses and then expands, and some heat and sound will also be generated. Therefore, the more pressure of ...
