WorksheetsRotational Motion Of a Rigid Body
Total questions: 10
Worksheet time: 10mins
A body with a definite shape that doesn't change is:
period
angular acceleration
rigid body
radius of gyration
The number of complete revolutions per second is:
frequency
period
torque
rotational inertia
The product of the force times the lever arm; the movement of the force about the axis is:
torque
lever arm
rotational inertia
angular momentum
If a system is in static equilibrium, it must have the following 2 conditions:
∑τ=0
Constant acceleration
∑F=0
Positive forces only
The formula used to find a torque is...
(m)(g)
(F) cos(Ɵ)
(F)(r)( sin θ )
(m)(a)
Conditions for equilibrium are:
1st condition: net force = 0
2nd condition:net torque = 0
True
False
The value of torque depends on the rotation axis and the _______________________
magnitude of applied force.
mass of object
moment inertia of object
shape of object
