Mechanics

Parent Category: Physics
Mechanics is the branch of physics that deals with the interactions of objects and forces in the observable world. Questions asking about projectile motion, conservation of energy, and calculus based mechanics are perfect for this topic, but questions about repairs that a mechanic would do belong in our vehicles categories.

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…
