Momentum

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity. It is a vector quantity, meaning it has both magnitude and direction.

Front

What is the formula for calculating momentum?

Back

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

Front

What are the units of momentum?

Back

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

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

What is the relationship between momentum and collisions?

Back

In a closed system, the total momentum before a collision is equal to the total momentum after the collision (law of conservation of momentum).

Front

What is the unit for velocity?

Back

The unit for velocity is meters per second (m/s).

Front

What is the unit for mass?

Back

The unit for mass is kilograms (kg).

Front

If an object has a mass of 2 kg and is moving at a velocity of 3 m/s, what is its momentum?

Back

The momentum is 6 kg m/s (p = 2 kg × 3 m/s).

Front

Which has more momentum: a 1 kg object moving at 5 m/s or a 2 kg object moving at 2 m/s?

Back

The 1 kg object has a momentum of 5 kg m/s, while the 2 kg object has a momentum of 4 kg m/s. Therefore, the 1 kg object has more momentum.
