NET FORCE PRACTICE PROBLEMS - Calculating the Net Force 2 & drawing a free body diagram
NET FORCE VIDEO SERIES - This EXTRA PRACTICEvideo shows an example of how to solve a Net Force problem in physics. This is an example of newtons second law of motion. You'll see how the force of gravity balances with newtons 3rd law showing equal and opposite forces. The surface is frictionless so the force of friction is zero. The acceleration is calculated using newtons 2nd law f=ma. Newton's first law states that there must be a net force acting on the object to make it sped up, slow down, or deviate from a straight line motion. Enjoy the video.
