"Torque, also called movement of force, measures how much a force rotates an object around an axis. Torque is the cross product of the force vector and the vector of the distance from the axis. The fo ...

"Gravitational force cannot be simulated, but the illusion of gravity can. All it takes for us to think we are being acted upon by gravity, is a force pulling us against a surface, generally the earth ...

"The speed at which an object rotates or revolves is called rotational speed. Unlike linear speed, it is defined by how many rotations an object makes in a period of time. The formula for rotational s ...

"Rotational inertia measures how much an object resists changing rotation. In linear motion, according to Newton's Second Law, we use mass to gauge an object's resistance to change but in rotational m ...
"It is important to understand the difference between rotations and revolutions. When an object turns around an internal axis (like the Earth turns around its axis) it is called a rotation. When an ob ...
"The law of conservation of momentum says that if two objects collide, the force lost by one object is equal to the force gained by the other object. The total momentum of the system is the same after ...

"Centripetal force causes an object in motion to continue in a curved path rather than a linear one. If this force stops, the object will continue in a tangential linear path. An example of centripeta ...

"Many students call centripetal force centrifugal force, but the two are not the same. Centrifugal force is the reaction to centripetal force as explained by Newton's Third Law of Motion, but it is on ...

"When the torques on either side of a fulcrum are equal, they are called balanced torques. A common example of balanced torques is two children on a see-saw. If the fulcrum is in the center of the see ...
