Conservation of Momentum

Front

What does the Law of Conservation of Momentum state?

Back

In a closed system, the total momentum before an event (like a collision) is equal to the total momentum after the event.

Front

What is meant by 'total momentum' in a collision?

Back

Total momentum is the sum of the momentum of all objects involved in the collision.

Front

If two objects collide and stick together, what happens to their total momentum?

Back

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

Front

What happens to the momentum of two colliding objects?

Back

Momentum is neither lost nor gained; it is conserved.

Front

In a collision, if one object gains momentum, what happens to the other object?

Back

The other object must lose an equal amount of momentum, keeping the total momentum constant.

Front

What is the formula for calculating momentum?

Back

Momentum (p) = mass (m) × velocity (v).

Front

If a 9 kg blob moving at 5 m/s collides with a 5 kg blob at rest, what is the final velocity of both blobs after they stick together?

Back

3.2 m/s.

Front

What is the relationship between momentum before and after a collision?

Back

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

Front

What happens to the velocity of a larger mass when it collides with a smaller mass?

Back

The larger mass may have a reduced velocity after the collision, depending on the interaction.

Front

What is an example of a perfectly inelastic collision?

Back

When two cars crash and crumple together, moving as one mass after the collision.
