... Hence when any object moves at constant velocity, all forces must cancel out, the net force must be zero. This law is also known as the law of inertia. The concept of inertia is that a massive object will remain at rest and will require a force to shift it, and once moving, will require a force to c ...

... for 0.40 s. What is the change in velocity for the bowling ball? (10.2 m/s) A 0.24-kg volleyball approaches Taylor with a velocity of -3.8 m/s. Taylor bumps the ball giving it a velocity of 2.4 m/s. What average force did she apply if the interaction time between her hands and the ball is 0.0254 s. ...
