Answer Rotational force is usually spoken of as torque. Torque is a term we use to talk about a force that acts on a body to change its rate of rotation. It is the rotational equivalent of force in a linear motion system. A torque can arise from a single offset-applied force (using "inertial for…

As a falling object accelerates through air, its speed increases and air resistance increases. While gravity pulls the object down, we find that air resistance is trying to limit the object's speed. Air resistance reduces the acceleration of a falling object. It would accelerate faster if it was fal…

Friction is caused by two or more surfaces rubbing together. At the molecular level, the particles are coming in contact with each other and, to put it simply, are sticking. The more particles there are in an object, the more they stick. This is called an objects adhesion potential.
