When analyzing collisions between objects, physicists define the total Momentum P of the system as the
sum of all the individual momenta. In particular, when no net outside force is defined, the total

Graph Matching
INTRODUCTION
One of the most effective methods of describing motion is to plot graphs of position, velocity,
and acceleration vs. time. From such a graphical representation, it is possible to determine in

Speeding Up (or Down): Acceleration
INTRODUCTION
Just like velocity, you likely already know about the basics of acceleration. Acceleration is how
fast your velocity changes. When driving on the highway, you hear squealing tire

Force & Motion (Solutions)
1) A 35-kg box on a floor feels a net force to the right of 400 N.
a) What is the acceleration of the box?
By Newtons 2nd Law: a = F/m = 400 / 35 = 11.4 m/s2
b) If the box starts from rest, how far will the
