This quiz contains 10 questions from a mix of 1 subtopics.
What is the point around which an object rotates called?
centre
axis
pivot
fulcrum
|
Which of the following is the correct unit for measuring moments?
newton-metre (Nm)
kilogram (kg)
newton (N)
metre (m)
|
What is the turning effect called when a force acts on an object that can rotate around a pivot?
equilibrium
torque
moment
rotation
|
Which of the following variables determine the size of a moment?
perpendicular distance from the pivot
both force and perpendicular distance from the pivot
neither force nor perpendicular distance from the pivot
force
|
What is the formula to calculate moments?
moment (Nm) = Force (N) ÷ Perpendicular distance from pivot (m)
moment (Nm) = Force (N) × Perpendicular distance from pivot (m)
moment (Nm) = Force (N) + Perpendicular distance from pivot (m)
moment (Nm) = Force (N) - Perpendicular distance from pivot (m)
|
If a child on a seesaw has a weight of 250 N and a distance of 2 m from the pivot, what is the moment?
500 Nm
750 Nm
1000 Nm
125 Nm
|
What happens when moments are balanced?
the object rotates clockwise
there is no net rotational effect
the object moves up and down
the object rotates anticlockwise
|
If the anticlockwise moment is greater than the clockwise moment, in which direction will the object move?
anticlockwise
up and down
clockwise
it will not move
|
Which of the following will increase the moment?
decreasing both the force and the perpendicular distance from the pivot
decreasing the perpendicular distance from the pivot
decreasing the force
increasing the force
|
The greater the force or from the pivot, the greater the resulting moment.
