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.

    reaction, energy is given out because the bonds in the products (CO2 and H2O) are stronger than those in the reactants (CH4 and O2). This shows that the products are more stable than the reactants. Some bonds are stronger than others and so require more energy to break them, but they also give out more energy when they are formed.

  1. Ohms Law.

    This means that the current is proportional to the p.d. The relationship is called Ohm's law. Ohm's law only applies if the temperature is constant, and does not apply to all electrical components. We can write Ohm's law in symbols: V ??I Or V = IR And R is the resistance of the resistor.
