to verify the principle of conservation of momentum

Question 1

how did the student measure the mass of the trolleys?

Answer 1

use a mass balance to measure the mass of the trolleys.

Question 2

state what measurements the student took and how these measurements were used to calculate the velocities.

Answer 2

masses of each cart, velocities were recorded using data loggers and speed sensors

Question 3

what adjustments did the student make to the apparatus so that body A would move at constant velocity

Answer 3

data loggers

Question 4

what formula is used to verify the principle of conservation of momentum in this experiment?

Answer 4

m1u1 + m2u2=m1+2v

Question 5

when carrying out this experiment the students ensures that there is no net external force acting on the bodies. what are the two forces that the student needs to take account of to ensure this?

Answer 5

friction and gravity

Question 6

describe how the student reduced the effects of these forces

Answer 6

tilted the track, remove dust from the linear air track, make sure the trollies connect together using velcro
