2.6,2.7 Circular Motion, Moments

An object following a __ path is acted upon a __ force at __° to its motion directed towards __ of circle

circular, centripetal, 90, centre

Define centripetal force.

force acting towards the centre of a circle

Formula for centripetal force?

F = mv² / r

Force will ↑ when:
↑M__

mass

Force will ↑ when:
↑V__

velocity

Force will ↑ when:
↓__

radius

On a roundabout, there is __ between the car & the road

friction

On a rope, there is __ in the rope

tension

A satellite has __ force around the earth

gravitational

As per Newton’s 1st Law:
If the string __, it will go in the direction __° to the string

broke, 90

Define moment.

turning effect of a force about its pivot

Moment↑ when:
↑__

force

Moment↑ when:
it is __° to the object

90

Moment↑ when:
it is __ from the object

further

Formula for moment?

M = fd

In the formula M = fd, d is?

perpendicular distance from pivot

What does the principle of moments state?
If an object is b__, total clockwise moment about pivot = total __ moment about pivot

balanced, anticlockwise

An object is in equilibrium when:
No __ f__ or m__

resultant force, moment
