The relationship between applied force and extension of a spring
This practical investigates how the extension varies with applied force for a spring, to determine if it obeys Hooke’s law.
What is the relationship between the force applied to a spring and its extension according to Hooke’s law?
they are directly proportional
What is the unit for the spring constant?
N/m
How is the extension of the spring calculated?
length - original length
How should the student treat an anomalous result in the acceleration practical?
ignore it and calculate the mean for the other points.
What does the Acceleration practical investigate?
The effect of varying the force on the acceleration of an object of constant mass, and the effect of varying the mass of an object on the acceleration produced by a constant force.
