TF + Centre of Gravity

Question 1

a moment is

Answer 1

the turning effect of a force

Question 2

formula for a moment

Answer 2

moment = force x perpendicular distance between line if action and pivot

Question 3

a larger _____ would mean a larger _______

Answer 3

force, moment

Question 4

a longer ______ = exert a larger ______ bc the ______

Answer 4

spanner, moment, distance from pivot is greater

Question 5

to get the maximum moment, you need to:

Answer 5

push at the right angles (perpendicular)

Question 6

pushing at any other angle =

Answer 6

a smaller moment. this is because the perpendicular distance between the line of action and the pivot is smaller

Question 7

where does the center of gravity hang?

Answer 7

directly below the point of suspension

Question 8

how to find the centre of gravity

Answer 8

suspend the shape and a

Question 9

if an object is balanced then

Answer 9

total anticlockwise moment = total clockwise moment

Question 10

if the moments are not equal

Answer 10

there will be a resultant moment, so the object will turn
