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

Respuesta :

Answer:

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:

[tex]Total\ Momentum\ Before\ Collision = Total\ Momentum\ After\ Collision\\\\m_{1}u_{1} + m_{2}u_{2} = m_{1}v_{1} + m_{2}v_{2}[/tex]

Answer:

A billiard ball of mass moves with a speed of and collides elastically with a ball of mass moving in the opposite direction with a speed of Show that because momentum is conserved in the rest frame, it is also conserved in a frame of reference moving with a speed of in the direction of the second ball.
