W****************** 3/6/19 PHYS170L Group 8 Lab 7: Collisions on an incline plane Objective: Test conservation of momentum and the transfer of energy from a collision using an inclined plane. ... Theory: Momentum should be conserved Mass can be found from a balance scale. A level track means there is no change in potential energy as cart moves Friction is ignored The ratio of energy transferred from object 1 to object 2 is called the energy There is only kinetic energy considered, so E of both carts = 1/2mv^2 μ = m1 m2 Transfer of energy ratio TE: TE = m v1 1 2 i m v2 2 2 f = μ v1 2 i v2 2 f = E1 E2 Speed of sound=343m/s Distance from sensor (position)= T/2*343m/s Velocity is found from the slope of position vs time graph. TE ratio SHOULD NOT be over 1 or else that means energy was created from a collision (this is illegal) Diagram: [Show More]
