P8.Forces In Balance Flashcards
What is displacement?
Displacement is distance without a change in direction
What is a vector quanity?
It has magnitude and direction
What is a scaler quanity
It has magnitude but no direction
What is distance?
The length between two points
(From point a to point b
What is an example of an vector quanity?
Displacement
Velocity
Force
Weight
Friction
What is an example of scaler quanities
Mass
Speed
Distance
Length
What is meant by a constant force?
Where two objects are physically touching
What is a force?
A push or pull
What is the formula of constant speed?
Total distance covered/total time taken
What is a momment?
Momment is a turning force around a piviot
What is the formula of momments
M=Fxd
Momments=Forcexdistance
What is a resultant force?
Two forces acting together
What is a contact force?
Is a force that occurs when two object make contact or touch
E.g,Firction
Two men pulling on a rope
What is a non contact force?
It is a force which acts on a object without physically touching
E.g,gravtitinaol force
A ball thrown in the air
What is a force multiplyier?
Force multiplyiers multiply the apllied force allowing you to lift more for less work.The apllied force is always further from the piviot that the force you are trying to overcome
