The units are that of mass: kg, g, lb, oz. Mass is a measure of the inertia of an object - the ratio of force to acceleration. Inertia = f/a = mknarl said:trying to figure out units for inertia.
am I right in saying some units for inertia are?:
imperial units - not interested (Wr^2)
kgfm^2 (GD^2)
kgm^2 (mr^2)
if so, what is the f and the G and the D?
Ok. Just use [tex]I = \tau/\alpha[/tex].knarl said:sorry, I meant moments of intertia. ie for a rotating body. It's just really the f that is putting me off.
Inertia is the resistance of an object to change in its state of motion. It is a measure of an object's mass and its tendency to continue moving in the same direction at the same speed.
Wr^2 GD^2 is a formula used to calculate the rotational inertia of an object. It takes into account the object's mass, radius of rotation, and distribution of mass.
mr^2 is another formula used to calculate the rotational inertia of an object. It takes into account the object's mass and its distance from the axis of rotation.
Inertia and Wr^2 GD^2 determine how difficult it is to change an object's rotational motion. Objects with a higher inertia or a larger Wr^2 GD^2 will require more force to change their rotational speed or direction.
Inertia and Wr^2 GD^2 are important concepts in engineering and physics. They are used in designing and analyzing rotating machinery, such as car engines, turbines, and flywheels. They also play a role in sports, as athletes must consider the inertia of their bodies and equipment in order to perform certain movements and tricks.
