When it comes to learning about energy and momentum as it pertains to the conservation of linear momentum, I couldn't help but think of last weeks experiment with the half rubber ball and the ping pong ball. The law of conservation of energy is very similar to the law of conservation of linear momentum. As the video in this weeks lesson details, as the ball falls down on the ground it amasses a level of kinetic energy. Once the basketball reaches the ground, it compresses storing elastic potential energy and once it shoots back up, it shifts is kinetic energy to the other balls which in turn makes the ball on top of go much higher than before. When you add a third ball to the equation, that transferred energy gets passed over to to that third ball and it to goes up much higher than the previous two. The reason that it goes much higher as the transfer of energy is happening is because of the reduced mass of each other other balls compared to the larger mass of the basketball. The energy stays the same but due to the other balls having a lighter mass, pushes them higher in the air.

When we watch the other two videos, a similar phenomenon occurs. The small balls are transferring energy from one ball to another and the increased rate of velocity pushes the ball further and further out and that is why you see the last ball shoot out at a great rate of speed. Truly a fascinating display of conservation of linear momentum.

I really enjoyed our concept this week. I feel like energy and momentum have a lot to do with my major, so it was fun reading about these concepts with my other class materials.

As we previously stated last week, energy cannot be destroyed, only converted. This occurs in our daily lives. We can see examples in kicking a ball, a car rolling in neutral, or a tennis player hitting a ball with their racket. All are examples of kinetic and potential energy exchange.

The first video provided explains the "double bounce theory." I'm sure you all have heard of this. This occurs When someone is able to bounce another person higher on a trampoline than if they were alone. The happens because the energy from person 1 is transferred to person 2 so their jump is significantly higher. In the video we are shown how the basketball transfers elastic potential energy through he rubber ball, into the golf ball. Because the energy is transferred, the basketball loses some of its height, but the golf ball can bounce much higher.

The second video explains magnetic momentum and energy transfer. We are shown multiple metal balls which have a magnetic charge. When the first ball is released, the attractive forces snap the ball forward causing a chain reaction. When the first ball hits the second set of balls, the energy is transferred all the way through until the next magnetic ball snaps forward again. This continues until there are no more balls to transfer energy to.

The final video depicts a similar concept of magnetic forces and momentum. The magnets are lined up in a way that propels the magnetic ball forward along a "track." Both are great ways to view the momentum and energy relationship.

Please respond to these statements Separately. I have the second one in bold to depict from the two.
