Momentum: The product of an object's mass and velocity.
Conservation of momentum: The principle that the total linear or angular momentum in any isolated system is constant, provided that no external force is applied.
What is the formula for momentum?
The formula for momentum is momentum=Mass times velocity
Why does the letter p stand for momentum?
The letter "P" came from the latin word petere which means "go towards", and "m" would have been too confused with mass.
How can a heavy moving van have the same momentum as a small motorcycle?
If a heavy moving van is moving at a low speed and a small motorcycle was moving at a high speed the momentum would be equivalent.
What is a sticky collision and a non sticky collision?
A sticky collision is when something has the same mass and gets tangled together when collided. After the objects collide they have the same momentum. A non-sticky collision is when two objects of the same mass don't stick together and outside forces are negligible, the objects trade velocities.
In an elastic collision two objects in which the total kinetic energy of the two bodies after the encounter is equal to their total kinetic energy before the encounter. An inelastic collision, in contrast to an elastic collision, is a collision in which kinetic energy is not conserved.
If you throw a piece of clay on the ground it would be an inelastic collision because none of the kinetic energy would be conserved.
What is angular momentum?
When an objects spins around in a circle instead of going in a straight line. In space, Planets, nebulae, stars, and black holes all spin around in a circle, thus they all have angular momentum.
