Unformatted text preview: Draw a free body diagram of a car standing still: Equilibrium (Newtons 1 st ) Object is at rest or moving at a constant velocity Net force = 0 Draw a free body diagram of a car driving at a constant velocity: Net force The force left over when all the forces have been resolved. Draw a free body diagram of a car accelerating forward: Newtons second law: F=ma A 1 kg soccer ball is kicked with a force of 30 Newtons. What is its acceleration? A car accelerates at 10 m/s 2 with a force of 30000 Newtons. What is its mass? Out: Draw a free body diagram of a boat accelerating through the water...
