Rotational Equilibrium
a state where an object has a net torque of zero, meaning there is no tendency for it to rotate and it is either at rest or spinning at a constant angular velocity
Translational equilibrium
an object is experiencing no net force acting on it, resulting in either a stationary state or a constant velocity motion
static equilibrium
a state where an object is completely at rest, meaning it has no motion, because all the forces acting on it are perfectly balanced, resulting in a net force of zero
Torque
a twisting force that causes an object to rotate around an axis
what is the basic equation for torque
τ = F r sin(θ)
Where should the fulcrum be placed on a seesaw that has two people with different weights to make it balanced
Closer to the heavier person
what is the general equation to find moment of inertia
I = ∑(m* r^2)
If the mass of the object stays the same and the radius is tripled, how is the moment of ineria affected?
the moment of inertia will increase by a factor of nine
If the radius of an object stays the same and the mass is tripled, how is the moment of inertia affected?
the moment of inertia of the object will also triple
