1.) Momentum: a characteristic of a moving object that is related to the mass and the velocity of the object.
2.) Conservation of Momentum: states that, in the abscence of outside forces like friction, the total momentum of objects that interact does not change.
3.) Momentum = Mass x Velocity
4.) It likely came from the Latin word "petere" which means "go towards." They couldn't use "m" because that was already used for mass.
5.) even though a heavy moving van has a large mass, a small motorcycle can have an equal momentum because the velocity of an object affects its momentum. so if the small motorcycle is traveling at a high speed, it can have the same momentum as a heavy moving van traveling at a lower speed.
6.) A "sticky" collision is when the objects stick together when they collide, they have the same mass, and one of the objects was at rest and one was in motion. A "non-sticky" collision is when two objects don't stick together when they collide, they have the same mass, and outside forces like friction are negligible so the objects just trade velocities.
9.) Inelastic collision because clay is not bouncy, it is sticky so whenever you throw it at the ground instead of it bouncing back up, the energy will be lost to the ground through sound and heat energy so it will stick to the ground.
10.) angular momentum is when the object spins around and around like a top instead of going straight like a baseball or a 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.
