Momentum

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, representing the quantity of motion an object has.

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 for momentum is kg x m/sec.

Front

How does mass affect momentum?

Back

The greater the mass of an object, the greater its momentum, assuming velocity remains constant.

Front

How does velocity affect momentum?

Back

The greater the velocity of an object, the greater its momentum, assuming mass remains constant.

Front

Which has more momentum: a heavy object moving slowly or a light object moving quickly?

Back

The heavy object moving slowly may have more momentum if its mass compensates for its lower speed.

Front

What happens to momentum in a closed system?

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 the principle of conservation of momentum?

Back

The principle states that the total momentum of a closed system remains constant if no external forces act on it.

Front

Calculate the momentum of a 10 kg object moving at 3 m/s.

Back

Momentum = mass x velocity = 10 kg x 3 m/s = 30 kg*m/s.

Front

If two objects collide and stick together, how do you calculate their combined momentum?

Back

Add the momentum of both objects before the collision to find the combined momentum.
