Hooke's Law
Introduction:
I am trying to find out what factors effect the stretching of a spring.
Factors which might affect the spring are:
· Downward force applied to spring.
· Spring material.
· Length of spring.
· No. of coils in spring.
· Diameter of spring material.
· Cross sectional area of spring.
I have chosen to look at the effect of the weight applied, as it is a continuous variation.
Prediction:
I predict that the more weight applied to the spring, the further the spring will extend. This is because when the load increases so does extension and stretching distance.
to find out how much something has been extended there is a little formula:
New size - Original size.
To prove that my prediction is correct I will experiment, and collect results using Hookes Law. He found that extension is proportional to the downward force acting on the spring.
Hookes Law
F= ke
F = Force in Newtons
k = Spring constant
e = Extension in Meters
Equipment list:
Boss clamp
metre rule
3 springs (different sizes)
0 weights (each 1N each)
Safety:
There are very few potential dangers whilst performing this investigation. The spring could snap and the stand could fall. To prevent these factors from dangers I shall wear goggles and make sure the stand is supported on both sides.
