1st
2nd
3rd
Gravitation
What are the units of moments?
J/s
Nm
W/m
N/m
What is meant by the moment of a force?
the instant a force acts
the effect that a force has
the turning effect of a force about a pivot
the acceleration of a force about a pivot
What happens to the moment of a force if the distance to the pivot is doubled?
The moment is halved
The moment remains the same
The moment is doubled
The moment is quadrupled
Which of the following conditions is necessary for an object to be in static equilibrium?
The object must be accelerating
There must be no forces acting on the object
The net force and net moment must both be zero
The object must be moving at a constant speed
Which condition must be met for an object to be in rotational equilibrium?
There must be no forces acting
The object must be stationary
The net moment must be zero
The net force must be zero
A
B
C
D
What happens to an object if the net force acting on it is zero?
It must be accelerating
It could be either stationary or moving at a constant speed
It must be stationary
It must be moving at a constant speed
What is the correct formula for the moment of a force?
Moment = force x distance
moment = force x distance to pivot
moment = force x perpendicular distance to pivot
moment = force / distance
What does it mean if an object is in equilibrium?
There is no movment
The object is stationary
The resultant force on the object is zero
There are no forces acting on the object
What happens to an object if the net moment acting on it is zero?
It must be rotating
It could be either stationary or rotating at a constant speed
It must be stationary
It must be accelerating
Which of the following is an example of a force causing an object to rotate?
Dropping a ball
Sliding a book across a table
Pushing a door open
Holding a cup

What is the effect on the moment of a force if the force is tripled while the distance to the pivot remains constant?
The moment is doubled
The moment is halved
The moment remains the same
The moment is tripled
