Momentum and energy changes in one-dimensional collisions

Physics HL


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




E.g. Total momentum= mass x velocity of trolley A + mass x velocity of trolley B

  • 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.

  1. Carbon track experiment

    This varies the results greatly and so this is why I shall not use these. The most commonly used would be the copper with the large surface are because it covers the carbon track more than any of the other materials.

  2. Find the realtionship between gravitational potential and kinetic energy

    Nevertheless, the results cearly show that the higher the ramp the faster the speed of th abll. This can be explained. The higher an object goes the more gravitational potential energy it gains. When the ball rolls down its potential energy is converted into kinetic energy and since energy can

  1. Ohms Law.

    It can be rearranged so that R is the subject, hence: R = V/I The larger the resistance, the greater the gradient will be. Gradient of the graph gives the value of resistance. Ohm's law does not always apply. A light bulb in place of the resistor in the circuit

  2. Find the efficiency of energy conservation of a staple fired by an elastic band.

    line and then we can find out the elastic energy stored from the area under the graph. If the elastic band does not obey Hooke's law then the results plotted will not give us a straight line and so I will estimate the elastic energy stored (area under the graph)

  1. The topic of which I have been studying is energy transfers, how energy can ...

    If one of my three results seems to be inaccurate I will ignore it and redo that result if I have time if not I will use the other two results to find the average. I will also circle any odd results that do not go with the pattern.

  2. Ohm's law.

    This shall be repeated three times for each length of wire to ensure that the test is fair. Then the crocodile clips shall be moved by another ten centimeters from the end of the wire. Another three readings shall be taken and the crocodile clips shall be moved another ten centimeters.

  1. To find out what happens to the efficiency of a motor as I change ...

    of the object has been lifted against the force of gravity. If an object can fall, it's got gravitational potential energy. The motor we used for our experiment was set up to lift a load 0.5 metres off the ground, in other words, the rotational kinetic energy of the motor's spindle is transferred into movement energy (the same type really)

  2. An investigation to find out how gravitational potential energy is converted into kinetic energy.

    From looking at the formula you can see that if the height is increased the speed will also increase. Applying this to our experimental situation; the higher the ramp is raised the more g.p.e is obtained, and therefore the higher the speed of the trolley.
