C. Mass & Geometric C. | Torque Flashcards
refers to the exact middle point of an object or shape in terms of its geometry. It is the point where, if the shape or object were cut out of a uniform material, it would balance perfectly.
Geometric Center
the point where the entire mass of the object can be considered to be concentrated.
Center of mass
It represents the average location of all the mass in a system
Center of mass
is a measure of the tendency of a force to produce a change in rotational motion
Torque
can refer to a line about which a body rotates. For instance, the Earth’s rotational axis is the line around which Earth spins, passing through the North and South
Axis
refers to the perpendicular distance between the line of action of a force and the pivot point or axis of rotation.
Lever arm (r)
is an imaginary straight line that extends through the direction in which a force is applied. It represents the path along which the force acts, and it helps to determine how the force influences motion, especially in rotational dynamics.
Line of action of a force
Resulting rotation is counterclockwise
T is Positive
Resulting rotation is counterclockwise
T is Positive
Resulting rotation is clockwise
T is negative
Resulting rotation is clockwise
T is negative
is a state in which an object is not rotating. In a state of equilibrium, we can express the net torque as 0.
Rotational equilibrium
Any object has tendency to resist any change in its motion.
Inertia
The tendency to resist any Rotational Motion
Moment of inertia
The tendency to resist any Rotational Motion
Moment of inertia
