What are the units for moment

Nm or Newton meter

A seesaw is unbalanced with two people of different masses sitting equal distances from the fulcrum. How we can move the smaller mass to make the seesaw balanced? closer to the fulcrum or further to the fulcrum?

further from the fulcrum

How is the principle of moment help in making the beam balance?

anti-clockwise moment = clockwise moment

Define " Moment "

it's a turning effect

The figure shows a man lifting a heavy rock using a steel bar. He pushes downwards on the end of the bar with a force F. Which pivot positions allows the force F to be as small as possible?

A

In a balanced seesaw the total clockwise moment = total anticlockwise moment .True or False

True

Calculate the distance of the objects from the fulcrum if the moment is 10 Nm

1 m

[True or False] Gravitational force on Earth is 10 N/kg

True

Which letter shows where you should apply the effort?

A

How can we increase the moment? mention 2 answer

1.Increase the distance from the force to the pivot 2.Increase the force applied

calculate the moment

20 Nm

A simple machine which consists of a beam resting on a pivot that help us carry heavy objects is called_____

A lever

which direction of this moment?

anti-clockwise moment

[True or False] equilibrium is unbalanced

False

[True or False] Weight = mass x gravitational force

True

calculate the moment

36 Nm

How to calculate moment ?

moment = force x distance (from fulcrum)

Calculate the moment!

2 Nm

Which letter is the pivot?

B
