Define linear momentum and identify the two physical quantities required to calculate it.

Linear momentum is defined as the product of an object's mass and its velocity. The two physical quantities required are mass and velocity.

What are the SI units for linear momentum?

The SI units for linear momentum are kilograms meters per second (kg*m/s).

Momentum (p) = mass (m) * velocity (v). p = 1500 kg * 20 m/s = 30,000 kg*m/s.

Impulse is the force that is applied times the duration of time that it is applied. Its SI units are Newton seconds (N*s).

Impulse is equal to the change in an object's momentum.

I can calculate the momentum of an object and apply the principle of conservation of momentum.

1
Linear momentum, represented by the letter p, is defined as an object's mass multiplied by its velocity.
2
The impulse applied to an object is the force applied multiplied by the duration of time it is applied, and it is equal to the object's change in momentum.
3
In a collision between objects, the total momentum will be conserved, meaning the sum of the momenta of the objects is the same before and after the collision.
