Chapter 6: Forces
... The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. ...

... When an object moves through any fluid, such as air or water, the fluid exerts a drag force on the moving object in the direction opposite to its motion. As the speed of the object increases, so does the magnitude of the drag force. The size and shape of the object also affects the drag force, ...

... Velocity is speed with direction. 6. How is acceleration related to velocity? Acceleration is change in velocity, that is, any change in speed, direction, or both. 7. A backpack falls out of an open window. The backpack starts from rest and hits the ground 1.0 second later with a velocity of 9.8 m/s ...
