Using two billiard balls, in 3-4 sentences, design an experiment to demonstrate the law of conservation of momentum.

In the explanation

Explanation:

Experiment:

Consider two billiard balls of masses ‘m₁’ and ‘m₂’, moving with velocities ‘u₁’ and ‘u₂’, respectively,  such that u₁ is greater than u₂. After some time, these balls collide with each other and their velocities  become ‘v₁’ and ‘v₂’, respectively.

Observation:

The masses of balls should be measured and their initial and final velocities should be measured.

Result:

In order to prove law of conservation of moment following equation must be satisfied by observed values:

answer: i'm not sure which is which for i get confused on it all the time but i can tell you that the answer lies with the convex and concave devices. i hope this you. have a good day and best of luck to you!

explanation:

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.
