Impulse and Momentum
The Impulse-Momentum Theorem
There are many situations when the
force on an object is not constant.
Our kinematic equations to describe
motion will not work for these situations.
Impulse and Momentum are used instead!

Freely Falling Bodies
In the absence of air resistance, it is found that all bodies
at the same location above the Earth fall vertically with
the same acceleration. If the distance of the fall is small
compared to the radius of the Earth, then the acceler

1. A car moving along a straight line on a flat horizontal surface undergoes a
constant acceleration of -3m/s2 (i.e. it is slowing down). If the initial speed of
the car is +25 m/s. How long does it take t

Purpose: The purpose of this lab was to find Pi.
Procedures:
This lab was provided with six different disks all ranging in size and mass. What was
needed to be found was the circumference, diameter, and the mass of each disk

Laws of Motion Homework
1. Three forces act on an object. A 5 N force acts due east and a 6 N force acts due north. If the net
force on the object is zero, what is the magnitude of the third force?
a. 7.8 N
b. Correct: Your answer is correct.
2. The net h
