net F = MA

As simple as this equation seems, it is a staple in mechanics. It has many different applications. These uses vary from setting up equations to find tensions to simply finding the net force of an object in motion. It is 0 when an object is in constant velocity or when the system is in static equilibrium. Then, when we convert the quantities into rotational motion, and we get net Torque = I(alpha). For an equation that seems very simple and easy to apply, there exist tricky problems that require us to be very careful with our directions of motion. However, with as much practice with them as we've done, they are easy points for our class!
