Forces: Contact Forces and Pressure - Key Terms Flashcards
1
Q
Equilibrium
A
State of an object when opposing forces are balanced.
2
Q
Deformation
A
Changing shape due to a force.
3
Q
Linear Relationship
A
When two variables are graphed and show a straight line which goes through the origin, and they can be called proportional.
4
Q
Newton
A
Unit for measuring forces (N)
5
Q
Resultant Force
A
Single force which can replace all the forces acting on an object and have the same effect.
6
Q
Friction

Force opposing motion which is caused by the interaction of surfaces moving over one another. It is called ‘drag’ if one is a fluid.
7
Q
Tension
A
Force extending or pulling apart.
