Stretched+Spring+Lab

__**HOOKE'S LAW LAB**__

__**Purpose:**__ Find relationship between force and change in distance of a spring (stretch).

__**Graph:**__ Force vs. Stretch

__**Calculations:**__

Rewrite the equations from your springs using the variables and units. Include R^2 values after the equation.

Example: Spring A: Force = 2.50 N/cm * change in distance + 1.3 x10^-5 cm r^2 = 0.987

__**Questions:**__

1. What is the relationship between force and stretch?

2. What does the slope of the line indicate?

3. Why do you think that the slope of the lines varied between springs?

4. What is the y-intercept?

5. What does the area under the curve represent?

6. Who was Robert Hooke and why is this lab named after him?
