Unit 4: Momentum, Impulse, Conservation, Collisions

Front

The momentum of an object depends upon the object's ___________&_____________.

Back

mass and velocity.

Front

Which one of the following units represents the standard metric units of momentum?

Back

Kilograms * meter / second.

Front

When the speed of an object is doubled, its momentum __________.

Back

doubles.

Front

The law of conservation of momentum states that, p before __________ is the same as p after __________.

Back

is the same as.

Front

While playing pool, Emma notices that the pool balls bounce apart. What type of collision is this?

Back

Elastic.

Front

Define momentum.

Back

Momentum is the product of an object's mass and its velocity.

Front

What is the formula for calculating momentum?

Back

p = m * v (where p is momentum, m is mass, and v is velocity).

Front

What is impulse?

Back

Impulse is the change in momentum of an object when a force is applied over a period of time.

Front

What is the relationship between impulse and momentum?

Back

Impulse is equal to the change in momentum (Impulse = Δp).

Front

What is an elastic collision?

Back

An elastic collision is one in which both momentum and kinetic energy are conserved.
