In this lesson, we will learn:

- the term "momentum" in everyday usage versus the physics definition
- standard units for momentum calculations
- problem solving with momentum

__Momentum__is the "quantity of motion", and can be thought of as how difficult it is to stop an object in motion.

**Momentum**

$\vec{p} = m \vec{v}$

$\vec{p}:$ momentum, in kilogram meters per second (kg∙m/s)

$m:$ mass, in kilograms (kg)

$\vec{v}:$ velocity, in meters per second (m/s)

- Introduction
Introduction to momentum and motion:

- the term "momentum" in everyday usage versus the physics definition
- standard units for momentum calculations

- 1.
**Finding the Momentum of an Object**a)a 1200 kg car traveling at 20 m/s [E]b)a 0.25 kg ball thrown upward with a velocity of 30 m/sc)a stationary truck weighing 2500 kg - 2.
**momentum = mass ∙ velocity**a)A 45 kg ice skater moving backwards has a momentum of 360 kg∙m/s. What is her velocity?b)A car travelling at 50 km/h has a momentum of 1.39×10^{4}kg∙m/s. What is its mass?
