What is the moment of a force?
The
turning effect
produced
by
a
force
View source
What are some examples of the rotation caused by the moment of a force?
Child on a
see-saw
,
door
opening
View source
What is a fixed pivot?
A point around which an object
rotates
View source
How can rotation be classified?
Clockwise
or
anticlockwise
View source
How can you determine the direction of rotation using a clock?
By
observing
the
hands
of
the
clock
View source
What happens when a force is applied on one side of a pivot?
It causes the object to
rotate
View source
What is the formula for calculating the moment of a force?
M
=
F
×
d
View source
What does each variable in the moment formula represent?
M = moment, F =
force
, d =
distance
View source
What is the significance of the forces being perpendicular to the distance from the pivot?
It maximizes the
moment
produced
View source
Why is it harder to push a door open near the hinges?
It requires more
force
due to
distance
View source
How does increasing the distance from the pivot affect the force required?
It
decreases
the
force
required
View source
In what units is the moment of a force measured?
Newton metres
(Nm)
View source
What does the principle of moments state?
Total
clockwise
moment equals total
anticlockwise
moment
View source
How can you determine if an object is balanced?
By checking if
moments
on both sides are equal
View source
What happens when a beam moves clockwise about a pivot?
The
applied force
is considered clockwise
View source
How do you calculate the total clockwise moments?
Sum of all
clockwise forces
multiplied by
distances
View source
What is the equation for balancing moments on a beam?
Sum of
clockwise
moments = Sum of
anticlockwise
moments
View source
How do you find the distance a child must sit from a pivot on a see-saw?
By using the
principle of moments
View source
What is the centre of gravity of an object?
The point through which the
weight
acts
View source
Where is the centre of gravity located in a symmetrical object?
At the
point of symmetry
View source
How can you find the centre of gravity of an irregular object?
By suspending it and using a
plumb line
View source
What happens to the centre of gravity when a body changes shape?
It shifts
depending
on the shape
View source
How should you draw force diagrams regarding the centre of gravity?
Draw
weight force
acting from the centre of gravity
