PHYS 25.1L - Experiment 6: Conservation of Momentum

Collision

An event in which two or more bodies come together with a resulting change of direction and energy (e.g. friends bumping, coins in coin bank)

Elastic, inelastic

two types of collision

conservation of momentum

"the total momentum before and after collision are equal"

symmetric

The collision of ball 1 and ball 2 is to be made __, such that one lands far right as the other lands far left

projectile launcher, meter stick, tape measure, manila paper, carbon paper, plumb bob, protractor

mats in experiment 6

Inward

the launcher must be aimed __ towards the table

down

the carbon paper must be taped side-__

2D collision accessory

Mounted to the front of the launcher to put the target ball

tee

part of the 2D Collision accessory where you place the ball 2

plumb bob

used to locate on the paper the spot directly below the point of contact spot

point of contact

the spot where the landing point of the ball at muzzle velocity is (ball 1)

reference line

line from the aim of launcher to the point of contact

landing lines

lines from point of contact to the center points of ball 1 and ball 2

5

You fire the ball straight ahead __ times
