Turning Effect/Moment of a Force

What is the unit of force?

• N

• Ns

• Nm

• N/s

What is the SI unit of distance?

• cm

• km

• m

• dm

which formula is correct for moment?

• M = F x t

• M = F/t

• M = F/d

• M = F x d

What is the unit of turning effect?

• N s

• N m

• kg s

• kg m

Find the moment if the force acted on an object is 24 N and its distance to the pivot is 4 m.

• 96 N cm

• 86 N cm

• 96 N m

• 86 N cm

Find the force exerted on an object if its distance to the pivot is 3 m and the moment is 75 Nm.

• 35 N

• 25 m

• 35 m

• 25 N

Find the distance of a force to the pivot if the exerted force on that distance is 125 N and the moment is 25 Nm.

• 5 N

• 25 m

• 5 m

• 25 Nm

Which formula is correctly used for F, M and d?

• F = M x d

• d = F/M

• F = M x d

• d = M/F

What will happen to a seesaw that has same moment on its clockwise and anticlockwise direction?

• Unbalanced

• Balance

• Nothing happened

Which formula that can be used to solve a problem about moment that using two different forces in different distance tend to the pivot? (the forces make an object in its balance condition)

• M clockwise = M anticlockwise

• M clockwise $\ne$ M anticlockwise
