Introduction

Momentum and energy changes in one-dimensional collisions

Physics HL

Introduction:

Conservation of momentum is one of the most important and universal of the conservation laws of physics; it holds true even in situations where modern theories of physics apply. That is amazingly useful because it means that ONE can tell what is going to happen after a collision before it has taken place.

Law of conservation of momentum: when two or more objects act on each other, their total momentum remains constant, provided no external forces are acting.

Law of conservation of energy: Energy is never destroyed; it is just converted from one form to another. body in motion possesses kinetic energy.The kinetic energy possessed by a body depends on itsmassand itsspeed.

Purpose: To verify the laws stated above, therefore find change in kinetic energy and momentum 0.

Momentum of a body of mass m, moving with velocityimage09.png, is given by p=mv.image08.jpg

The units of momentum are kgms-1

i.e                                 m1v1 + m2v2 = m1v1 + m2v2

Conclusion

  • Take uncertainty of 1% in every single piece of data, final result will then be a lot more accurate, but time limits.
  • Make more trials to verify laws, more than 4 times at least.
  • Take uncertainty in consideration more carefully following rules of finding uncertainties.
  • Describe method in more details so that anyone can follow it.
  • Make sure there are no time limits next time.
  • Draw more diagrams to show apparatus after each step.

    Resistance The four factors that affect the resistance of a piece of wire: Length, Diameter or thickness, Temperature and The type of metal. From thinking about how I would do this investigation and the outcome of it, I decided to use the length of the wire as the variable.

    as all the potential energy has transferred into kinetic making the ball roll faster. The ball will travel faster at the highest height because the higher the ramp the more potential energy, therefore transferring into more kinetic energy.

  1. Ohm's law.

    The resistance across this section shall be considered negligible. The use in this test is to determine how much resistance there is in the circuit wires, connected to the test wires. This shall be my "control". This will ensure that the test is fair.

  2. Carbon track experiment

    In other words, when investigating how length affects the resistance, the width would be kept constant and visa versa. This is because otherwise I will not be able to extinguish whether there was a change in resistance due to the change of length or width.
