Hooke’s Law Force=-KΔx K is the spring constant, measured in  newtons/meter - means that the spring is pulling in the  opposite direction of the stretch Δx is the amount of stretch in meters

Unformatted text preview: force of 8 N. How far has it been stretched? Lab: Hookes Law Problem: Measure the spring constant of a given spring. Background information Hypothesis: make a guess, K=force of the spring stretched 1 meter Procedure: diagram and explanation Data: make a table Analysis: graph, calculations Conclusion: Conclusion How much force will a spring with a spring constant of K=225 N/m, pull back if it is stretched 40 cm? Out: How could you use your knowledge of Hookes law to make your car win the race? Remember your synthesis! Picture: What you own, what you dont understand...
