Force Flashcards
1
Q
What is the equation for rf?
A
Rf = ma
(Resultant force = mass × acceleration)
2
Q
What is the equation for Hooke’s law?
A
Applied force = spring constant × extension
(f = ke)
3
Q
What is the Principle of Moments?
A
In equilibrium the total clockwise moment about a point equals the total anticlockwise moment about the same point.
4
Q
What does Hooke’s law state?
A
The extension of a spring is directly proportional to the applied force, provided the limit of proportionality has not been exceeded.
5
Q
What does Hooke’s law state?
A
The extension of a spring is directly proportional to the force applied, provided that the limit of proportionality has not been exceeded.
