Effect of Force
Force can cause the following effect to objects.
increase the speed of a moving object
move a stationary object
stop a moving object
change direction of a moving object
change the shape of an object
6.5 moment of force
Turning effect is applied when we close or open
A door. This turning effect is known as torque or
Moment of force. The SI unit of the moment of force
Is newton meter as moment is the product of force
And perpendicular distance from the pivot and the
Fulcrum.
Determining the moment of force
Moment of the force at A=2Nx0.1m
=0.2nm
The moment of fore is called the anticlockwise
Moment as the force turns the flip cover in the
Direction against the clock hands movement if it
Follow the movement of clock hands.
Science discovery
There are a lot of
Activities that involve the
Use of moment of
Force other than opening
Door?
