Why the torque is called moment of force and angular momentum is called moment of linear momentum ? Please explain.
Torque is a measure of the force that causes an object to rotate around an axis. It is calculated by multiplying the force applied to an object by the distance from the axis of rotation to the point where the force is applied.
Moment of force is another term for torque, and they are essentially the same concept. Torque is commonly used in physics, while moment of force is more commonly used in engineering.
Angular momentum is a measure of an object's rotational motion. It is calculated by multiplying the angular velocity (how fast the object is rotating) by the moment of inertia (the object's resistance to change in rotation).
Moment of momentum is another term for angular momentum, and they are essentially the same concept. Angular momentum is commonly used in physics, while moment of momentum is more commonly used in engineering.
Torque and angular momentum are both considered moments because they are both measures of rotational motion. The terms "moment of force" and "moment of momentum" are used to emphasize the fact that these quantities are related to the moment (or turning effect) of a force or motion around an axis of rotation.
