Momentum

Front

What does momentum depend on?

Back

Momentum depends on an object's mass and velocity.

Front

What is always constant in any collision?

Back

Total Momentum is always constant in any collision.

Front

What happens to momentum when the speed of an object is doubled?

Back

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

Front

What is Newton's Third Law?

Back

For every action, there is an equal and opposite reaction.

Front

If a 9 kg blob moving at 5 m/s collides and sticks to a 5 kg blob, what is their combined velocity?

Back

The combined velocity of the two blobs is 3.2 m/s.

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

The formula for momentum (p) is p = mass (m) x velocity (v).

Front

What is the unit of momentum?

Back

The unit of momentum is kilogram meter per second (kg·m/s).

Front

Explain the principle of conservation of momentum.

Back

The principle of conservation of momentum states that in a closed system, the total momentum before and after a collision remains constant.

Front

What is an elastic collision?

Back

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