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

And write like a fifth grader

Sure! So, to show the law of conservation of momentum, we can take two billiard balls of the same size and weight. First, we will make one ball move by hitting it with a cue stick. Then, we will see that when this ball hits the other ball, the second ball will start moving too. This happens because the momentum from the first ball is transferred to the second ball, showing that momentum is conserved in the collision between two objects.
