Forces that Accelerate


This week we talked about forces that accelerate. Newton’s 2nd Law tells us that the acceleration of an object is directly proportional to the net force of an object, and the acceleration of an object is inversely proportional to the objects mass. In simpler terms we just have to remember an equation. This equation is Fnet=ma. Where Fnet is the sum of all forces, m is the mass, and a is the acceleration. In previous units we dealt with gravitational pull, which comes into play here as well. The gravitational acceleration is 9.8 m/s2. This is important to remember. In this image my moms cousin, and his wife are riding a motorcycle. Simply put if a bug were to hit the bike, the forces would be equal of both objects. This is because the bug hit the bike, and the bike hit the bug. It is an equal force.
