# Momentum

The quantity of motion of a moving body, measured as a product of its mass and velocity.

The formula for momentum is momentum = mass * velocity and is usually appreviated by p = m * v

# How can a heavy moving van have the same momentum as a small motorcycle?

They could have the same momentum if the motorcycle is going fast and the van is going slow.

If the van weighs ten times as much as the motorcycle, and is driving 5 mph it would have the same momentum as the motorcycle driving 50 mph.

# What is the difference between a sticky collision and a non sticky collision?

in a non sticky collision the objects just trade velocity , in a sticky collision the object stick together an carry the same momentum.

an inelastic coliision

Elastic collision

# What type of collision would you think throwing a piece of clay onto the ground would be?

Well, if they clay was hard enough to bounce even just a little, it would be elastic. but more likely than not the clay would be soft and stick to the floor so in that case it would be inelastic.

# What is angular momentum and how does it effect space?

This is when the object spins around and around like a top instead of going straight like the baseball or the car. Again, bigger things and faster things are harder to stop. In space, nebulae, stars, black holes, and planets all have angular momentum, and they all spin around.

# Oh yea and go packers!!!!!!!

The law of conservation of momentum tells us that you can't just lose momentum - it has to go somewhere.

# Now why is momentum represented with a "p"?

No one is quite sure why "p" is used for momentum. It likely came from the Latin word "petere" which means "go towards". They couldn't use "m" because that was already used for mass.

im so sorry it is very out of order but its all there! @titanslaxmom
