How does air resistance affect an object in free fall?
... ball dropped through the air from a predetermined height. Newton’s Second Law states that in the presence of unequal force, an object will accelerate and, therefore, its speed, direction or both will change. In this case, the opposing forces acting on the ball, gravity and air resistance, fight to c ...

Chapter 10: Dynamics of Rotational Motion
... The equation z=Iz is useful whenever torques act on a rigid body - that is, whenever forces act on a rigid body in such a way as to change the state of the body’s rotation. In some cases you may be able to use an energy approach instead. However, if the target variable is a force, a torque, an ac ...
