Q
Extension
A
The increase in the length of a spring when a force is exerted on it.
2
Q
Normal force
A
A force that acts perpendicularly to the object’s surface.
3
Q
Parallelogram method
A
Method for finding the resultant when two forces have some arbitrary angle between them.
4
Q
resultant
A
The sum of the forces acting on an object. The forces have to be addes as vectors, not as numbesr.
5
Q
spring constant
A
Property of a spring that indicates how far the spring extends when a force is exerted on it.
6
Q
zero position
A
The length of a spring that has not been extended.
7
Q
