Physics Introduction to 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 happens to momentum when the mass of an object increases while velocity remains constant?

Back

If the mass of an object increases and velocity remains constant, the momentum of the object increases.

Front

What is the unit of momentum?

Back

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

Front

If two objects have the same momentum, what can be said about their mass and velocity?

Back

If two objects have the same momentum, they can have different masses and velocities, as long as the product of mass and velocity is equal.

Front

What is the principle of conservation of momentum?

Back

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

Front

How does doubling the speed of an object affect its momentum?

Back

Doubling the speed of an object doubles its momentum, since momentum is directly proportional to velocity.

Front

What are the two factors that affect momentum?

Back

The two factors that affect momentum are mass and velocity.

Front

If a 5 kg object is moving at 3 m/s, what is its momentum?

Back

The momentum is 15 kg m/s (calculated as 5 kg × 3 m/s).

Front

Can an object have momentum if it is at rest?

Back

No, an object at rest has zero momentum because its velocity is zero.
