IB Physics Moments GCSE Recap

What is meant by the moment of a force?

• the instant a force acts

• the effect that a force has

• the turning effect of a force about a pivot

• the acceleration of a force about a pivot

What is the correct formula for the moment of a force?

• Moment = force x distance

• moment = force x distance to pivot

• moment = force x perpendicular distance to pivot

• moment = force / distance

What are the units of moments?

• J/s

• Nm

• W/m

• N/m

An object will not accelerate unless a resultant force acts on it. Which of Newton's Laws is this?

• 1st

• 2nd

• 3rd

• Gravitation

What does it mean if an object is in equilibrium?

• There is no movment

• The object is stationary

• The resultant force on the object is zero

• There are no forces acting on the object
