It is calculated by multiplying the force by the distance from the axis of rotation to the point where the force is applied.<\/p>\n<p>Work is the amount of energy transferred to an object by a force acting on it. It is calculated by multiplying the force by the distance over which the force acts.<\/p>\n<p>Torque is the rotational equivalent of force. It is calculated by multiplying the force by the distance from the axis of rotation to the point where the force is applied.<\/p>\n<p>Angular momentum is a measure of how much an object is rotating. It is calculated by multiplying the mass of an object by the square of its radius of rotation and the angular velocity of the object.<\/p>\n<p>Planck&#8217;s constant is a fundamental constant of nature that appears in many equations in quantum mechanics.
