About this unit
Understanding interactions between force, mass, acceleration, and momentum allows us to predict and how an object will move and comes in handy when we're designing things like airplanes or seismically-reinforced buildings. Let's start exploring what these terms mean and how they relate to one another!Newton may not have been a Jedi, but he sure knew a lot about force.
