Momentum

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the formula p = mv, where p is momentum, m is mass, and v is velocity.

Front

How is momentum calculated?

Back

Momentum (p) is calculated using the formula: p = mass (m) × velocity (v).

Front

What is the unit of momentum?

Back

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

Front

If a 0.250 kg cart is moving at 0.400 m/s, what is its momentum?

Back

0.1 kg·m/s.

Front

What happens to momentum in a closed system during a collision?

Back

The total momentum before the collision is equal to the total momentum after the collision.

Front

What is the principle of conservation of momentum?

Back

In a closed system, the total momentum remains constant if no external forces act on it.

Front

In a collision, if two objects collide and one is at rest, how is the momentum transferred?

Back

Momentum is transferred from the moving object to the stationary object, causing it to move.

Front

What is the momentum of a 50 kg ball rolling at 5 m/s?

Back

250 kg·m/s.

Front

What is the relationship between mass, velocity, and momentum?

Back

Momentum increases with either an increase in mass or an increase in velocity.

Front

What is the total momentum in a system of two colliding objects?

Back

The total momentum is the sum of the individual momenta of both objects before and after the collision.
