Linear Momentum:
* A bowling ball rolling down a lane: The heavier the ball, and the faster it rolls, the more momentum it has. This is why a bowling ball can knock down pins even if it's not thrown very hard.
* A car traveling at a high speed: A car moving quickly has a lot of momentum, which is why it takes a long time and distance to stop.
* A bullet fired from a gun: Bullets are small but have very high velocity, giving them a significant amount of momentum.
Angular Momentum:
* A spinning figure skater: As a figure skater pulls their arms in close to their body, their rate of rotation increases. This is because they are conserving their angular momentum.
* A spinning top: A spinning top stays upright due to its angular momentum. The faster it spins, the longer it will stay upright.
* A planet orbiting a star: Planets have angular momentum due to their movement around the star. This is why planets stay in their orbits and don't just fly off into space.
Momentum in everyday life:
* A swinging pendulum: The pendulum has maximum momentum at the bottom of its swing and zero momentum at the top.
* A bouncing ball: The ball has momentum going down and momentum going back up.
* A moving train: A train has a huge amount of momentum, which is why it takes a long time to stop.
Key takeaway: Momentum is the measure of how much "motion" an object has. The more mass or velocity an object has, the more momentum it has.
