Momentum

Front

What is the formula for calculating momentum?

Back

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

Front

What are the units of momentum?

Back

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

Front

If a car has a mass of 1500 kg and is moving at a velocity of 30 m/s, what is its momentum?

Back

The momentum is 45000 kg·m/s.

Front

How does momentum change when the mass of an object is increased while keeping velocity constant?

Back

The momentum increases proportionally with the increase in mass.

Front

What happens to the momentum of an object if its velocity is doubled?

Back

The momentum of the object also doubles.

Front

What is the relationship between momentum and velocity?

Back

Momentum is directly proportional to velocity; as velocity increases, momentum increases.

Front

What is the principle of conservation of momentum?

Back

The principle states that in a closed system, the total momentum before an event is equal to the total momentum after the event.

Front

What is the momentum of a 0.5 kg object moving at 2 m/s?

Back

The momentum is 1 kg·m/s.

Front

How does the direction of velocity affect momentum?

Back

Momentum has both magnitude and direction; it is a vector quantity, so the direction of velocity affects the direction of momentum.

Front

What is the effect of friction on momentum in a real-world scenario?

Back

Friction can cause a loss of momentum as it opposes the motion of an object.
