Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe correct answer is Torque.
- Torque is the measure of the force that can cause an object to rotate about an axis.
- Torque Formula
- In physics and mechanics, torque is the rotational equivalent of linear force. It is also referred to as the moment, moment of force, rotational force or turning effect, depending on the field of study.
- Torque is commonly denoted with a capital “T,” but the correct symbol is the Greek letter tau, “τ.” When torque is referred to as a moment of force, the symbol “M” is used.
Additional Information
| Moment of inertia |
The moment of inertia is defined as the quantity expressed by the body resisting angular acceleration which is the sum of the product of the mass of every particle with its square of a distance from the axis of rotation. Formula |
| Linear momentum |
Linear momentum is defined as the product of a system's mass multiplied by its velocity. In symbols, linear momentum is expressed as p = mv. Momentum is directly proportional to the object's mass and also its velocity. Formula |
| Angular momentum |
In physics, angular momentum is the rotational equivalent of linear momentum. It is an important quantity in physics because it is a conserved quantity the total angular momentum of a closed system remains constant. Formula |
