Moments

Question 1

What is a moment

Answer 1

The turning effect of a force

Question 2

Equation to find moment

Answer 2

M=Fd

Question 3

As you increase the distance from which the force occurs around a pivot what happens to the moment

Answer 3

In increases

Question 4

What happens to the moment if u increase the force applied around a pivot

Answer 4

It increases

Question 5

How can u achieve the maximum momentum/turning effect

Answer 5

You need to push perpendicular (at a right angle) to the object

Question 6

What happens if the total anti-clockwise is equal to the the total clockwise moment about a pivot

Answer 6

The object is balanced and will not turn

Question 7

What do levers do

Answer 7

Increase the distance from the pivot at which the force is applied, so less force is needed to get the same moment

Question 8

What are gears

Answer 8

Circular disks with teeth around their edges

Question 9

How do gears work

Answer 9

-there teeth interlock so that turning one causes the other to turn in the opposite direction

Question 10

What are gears used for

Answer 10

To transmit the rotational effect of a force from one place to another

Question 11

What can different sized gears be used for

-They are used to … the moment of a …
-a force t… to a … gear will cause a … moment
-… gears turn slower that … gears

Answer 11

-They are used to change the moment of a force
-a force transmitted to a larger gear will cause a bigger moment
-larger gears turn slower that smaller gears
