Collisions and Momentum in Physics

The video explores the concept of elastic collisions starting with a 1 kg block on a frictionless plane. When it collides with another 1 kg block, it transfers all its momentum. Introducing an immovable wall, the video shows that with three collisions, the blocks reverse direction. Increasing the mass of the first block to 100 kg results in 31 collisions, and further increasing it to 10,000 kg results in 314 collisions. The number of collisions aligns with the digits of pi as the mass increases by powers of 100.

What happens when a 1 kg block collides with another 1 kg block on a frictionless plane?

• The blocks lose energy and stop.

• The blocks explode.

• The first block transfers all its momentum to the second block.

• The blocks stick together.

How many total collisions occur when a 1 kg block hits another 1 kg block and bounces off an immovable wall?

• 3

• 1

• 2

• 4

When the mass of the first block is increased to 100 kg, how does it affect the number of collisions?

• The number of collisions decreases.

• The number of collisions becomes infinite.

• The number of collisions remains the same.

• The number of collisions increases to 31.

What is the total number of collisions when the first block's mass is 100 kg?

• 10

• 20

• 31

• 50

What is the total number of collisions when the first block's mass is increased to 10,000 kg?

• 100

• 200

• 500

• 314

As the mass of the first block increases by powers of 100, what pattern emerges in the number of collisions?

• The number of collisions becomes random.

• The number of collisions doubles each time.

• The number of collisions decreases.

• The number of collisions matches the digits of pi.
