Which of the following is an example of an unbalanced force?
Calculate the resultant force.
40N, Left
40N, Right
0N, Balanced
75N, Right
The sum of all forces acting on an object is
balanced.
unbalanced.
friction.
the net force.
What is stated with Principle of Moment of Forces?
Apakah yang dinyatakan oleh Prinsip Momen Daya?
Anticlockwise Moment is the same as Clockwise Moment / Momen Lawan Arah Jam adalah sama dengan Momen Ikut Arah Jam
For a system to be in equilibrium, the total of anticlockwise moment must be the same as its clockwise moment / untuk sesuatu sistem dalam keseimbangan, jumlah Momen Lawan Arah Jam adalah sama dengan Jumlah Momen Ikut Arah Jam
To be in equilibrium state, the resultant force must be ZERO / Untuk berada dalam keseimbangan, daya paduan mestilah SIFAR
For a beam to be in equilibrium, the center of gravity must be in the middle of the beam / Untuk palang berada dalam keseimbangan, titik graviti mestilah berada di tengah-tengah
Choose the CORRECT statement for Moment of Force
Pilih kenyataan yang BETUL untuk Momen Daya
Moment of Forces is the effects of forces in increasing the velocity of object / momen daya ialah kesan daya dalam meningkatkan halaju objek
Moment of Forces is a measure of the effectiveness of the force in producing rotation about that axis / momen daya ialah pengiraan keberkesanan daya dalam menghasilkan pusingan setempat pada paksi
Moment of Forces can be calculate by dividing the Force, F with the arm distance, d / momen daya dikira dengan membahagikan Daya, F dengan jarak lengan, D
Moment of Forces can be used to determine the center of gravity for object in equilibrium / momen daya boleh digunakan untuk mencari titik graviti bagi objek dalam keseimbangan
One of the effects of forces on the object is......
Salah satu kesan daya ke atas objek ialah.......
move stationary object / gerakkan objek pegun
stop stationary object / hentikan objek pegun
change the stationary object / mengubah objek pegun
oppose the motion of the object / menghalang gerakan objek
Unbalanced force is when......
Daya tidak seimbang adalah apabila....
there is NO net force acting on the object / apabila TIADA jumlah daya yang bertindak ke atas objek
the net force acting on the object is equal to ZERO (F = 0) / jumlah daya yang bertindak ke atas objek ialah SIFAR ( F = 0)
there is net force acting on the object / terdapat sejumlah daya yang bertindak ke atas objek
object at rest or moving with constant velocity / objek dalam keadaan rehat ataupun bergerak dengan halaju seragam
Objects will continue to do what they are doing until a net, or unbalanced force acts on the object.
This statement explain.......
Objek akan cuba mengekalkan keadaan asal sehinggalah terdapat satu daya tidak seimbang yang bertindak ke atasnya.

When an object is in equilibrium, which equation is true?
Clockwise moment = anticlockwise moment
Clockwise moment + anticlockwise moment = 0
Clockwise moment / anticlockwise moment = 0
Clockwise moment + anticlockwise moment = resultant force
The SI unit of moment of force is –
m
N
kgf
Nm
The moment of a force causes an object to
move forward
move backward
stop moving
turn about a fixed point
