What does it mean if a system's momentum is 0 kg*m/s?

Back

The objects within the system may be moving, but the location of the center of mass is not changing.

Front

What is momentum?

Back

Momentum is a vector that points in the same direction as velocity.

Front

What happens to the momentum of two colliding objects?

Back

Object A and Object B will have the same magnitude of momentum change, but one will gain and one will lose.

Front

What is impulse?

Back

Impulse is the effect of a force acting over a period of time.

Front

What is the principle of conservation of momentum?

Back

The total momentum before a collision (P_i) is equal to the total momentum after the collision (P_f), so P_f = P_i.

Front

How is momentum calculated?

Back

Momentum (p) is calculated as the product of mass (m) and velocity (v): p = m * v.

Front

What is the unit of momentum?

Back

The unit of momentum is kg*m/s.

Front

Is momentum a scalar or vector quantity?

Back

Momentum is a vector quantity.

Front

What factors affect the momentum of an object?

Back

The momentum of an object is affected by its mass and velocity.

Front

What happens to momentum in an elastic collision?

Back

In an elastic collision, both momentum and kinetic energy are conserved.
