Conservation Of Momentum/Energy

Contains a collision experiment carried out surrounded by two colliding pool balls.

Also have movies that were analyised too (are rather large charge ups)

images custom work but ill upload the actual file also.

Conservation of Momentum & adenosine monophosphate; Energy

Aim:

To find whether momentum is conserved between two billiards balls of same mass colliding head on, with superstar macrocosm in a stationary position, & how divergent velocities and surfaces coin the conservation.

Theory:

In all collisions (closed system), momentum is conserved, so long as no external forces are acting. Variables that shall be changed are the surfaces that the collision shall contend place on (friction varies), the initial velocity of the ball, and the spin around on the ball. Variables, which shall not be changed, pass on be the mass of the balls

Hypothesis:

Momentum & energy shall be mostly conserved, but some will be lost due to friction and air knot forces, as the system isnt closed. Some energy will be lost through sound and heat transfer upon collision.

Equipment:

·         swayer (1m)

·         2 billiard balls of equal mass (0.26kg)

·         Pool Cue

·          pic Camera (with highest frame rate possible)

·         Tripod

·         Varying flat surfaces with different levels of friction, eg pool table, carpet, glass

·         VideoPoint 2.

·         Microsoft Excel

Method:

1.         Place the ruler on the level surface, and frame-up the camera on the tripod to be side on and at the same level as the collision, and also so that from 0 to 80cm can be viewed through the viewfinder.

2.         Once this is setup, place one ball at the 0cm mark, and the other at the 50cm mark

3.         Start the video camera recording and hit the 1st ball (white) at the 0cm mark with the pool cue dead on, with no spin applied to the ball,
