Physics Introduction to Momentum

Momentum is the product of an object's mass and its velocity, represented by the formula p = mv.

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

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

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

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

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

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.

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

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

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.
