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.

Front

What is the formula for calculating momentum?

Back

The formula for momentum is p = mv, where p is momentum, m is mass, and v is velocity.

Front

What is the unit of momentum?

Back

The unit of 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 happens to momentum in a closed system?

Back

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

Front

What is the relationship between momentum and force?

Back

Force is the rate of change of momentum; F = Δp/Δt, where F is force, Δp is change in momentum, and Δt is change in time.

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.

Front

What is the momentum of a 5 kg object moving at 3 m/s?

Back

The momentum is 15 kg m/s (p = mv = 5 kg * 3 m/s).

Front

If two objects collide, what can be said about their momentum?

Back

The total momentum of the two objects before the collision is equal to the total momentum after the collision, assuming no external forces act on them.
