Momentum and Impulse
Quarter 4 Module 4
2
What is momentum?
This is also known as inertia in motion
It is operationally defined as the product of the mass and the velocity of the object
It is measured using the unit kg.m/s or Ns (Newton second)
3
Factors Affecting Momentum
Momentum is affected by mass and velocity.
For two objects having the same velocity, the bigger object has greater inertia and therefor has greater momentum
4
Multiple Choice
5
Formula for Computing for Momentum
Momentum (p) is equal to the mass of the object (kg) multiplied to its velocity (m/s)
6
Let us try to solve this problem on momentum
In this problem we can see that the mass of the bird is 0.018kg and its velocity is 15m/s.
Using the formula p = mv, we can see that the bird's momentum is 0.27kg.m/s or 0.27Ns

Let us try to solve this problem
8
So tell me, what was your answer?
If you have answered baseball then you are correct!
The baseball has a momentum of 0.98Ns whereas the golf ball has a momentum of 0.72Ns
9
What is impulse?
It is the external force that acts on an object over a period of time that changes its momentum
It is measured in Ns or Newton second
Formula: Impulse (I) is equals to force (N) multiplied with time (s)
10
Try to solve this problem
In this problem, the object was pushed using a force of 120N. The time that the force was exerted was 35s. Therefore, the impulse is 4,200Ns.

Solve for the impulse

What is your answer?
If you got 50Ns then you got the right answer!
