"A vector contains two types of information: a magnitude and a direction. The magnitude is the length of the vector while the direction tells us which way the vector points. Vector direction can be gi ...

"A scalar quantity contains a magnitude and operates independently of direction while a vector quantity contains a direction. Most scientific data are scalar. A few examples of scalar quantities inclu ...
"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 ...
"Instantaneous velocity is the velocity of an object in motion at a specific point in time. This is determined similarly to average velocity, but we narrow the period of time so that it approaches zer ...

"The two most commonly used graphs of motion are velocity (distance v. time) and acceleration (velocity v. time). In each case, time is shown on the x-axis. The graph of velocity is a curve while the ...

"Speed refers to the rate at which an object travels. Unlike velocity, speed is a scalar quantity so direction does not matter. Instantaneous speed is the speed of an object in motion at a specific po ...
"An object is in free fall when gravity is the only force to move it through space. In reality, free fall is affected by variables such as wind iance, but when physicists discuss free fall, they gener ...

"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 ...
