6.5.1.4 resultant forces Flashcards
1
Q
What is a/ the resultant force
A
A number of forces acting on an object may be replaced by a single force that has the same effect as all the original forces acting together.
2
Q
How to work out force applied
A
Force applied - spring constant x extension
3
Q
What is force measured in
A
Newtons N
4
Q
What is the spring constant measured in
A
Newtons per metre N/m
5
Q
Extension is measured in
A
Metres, m
6
Q
What does the spring constant represent
A
The stiffness of a spring- the higher the spring constant, the higher the stiffness of the object
7
Q
How to work out the extension
A
Final length minus the original length
