1. Momentum and Impulse in 1 dimension
Concepts and Mathematical formalism

2. So what exactly is Momentum?
Momentum is frequently referred to as “ mass in motion”
Momentum is the “quantitative” description of Inertia
Newton originally used the concept of inertia/momentum to mathematically derive
We will only study momentum in 1 and 2 dimensions

3. Mathematical equation of momentum
So, how do we define momentum mathematically?
Well, lets start by choosing a letter to mathematically represent inertia…

4. Impulse
So, now that we know how to describe momentum, what about impulse?
Impulse is defined as the change in momentum over a given time interval
That is, an impulse applied to an object changes it momentum
So what makes impulse such an important quantity?

5. Conclusions Momentum is a vector and has units kg m/s
Momentum is the mathematical description of inertia
Momentum is a vector and has units kg m/s
The impulse applied to an object is equal to the objects change in momentum
Impulse is also a vector, and has the units Ns
