How to use the Spring equation Force = Spring Constant x Extension

How to use the Spring equation Force = Spring Constant x Extension

How to use the Spring equation If we want Force, cover up Force ÷

How to use the Spring equation If we want Force, cover up Force ÷ Spring Constant X Extension We multiply the Spring Constant by the Extension

How to use the Spring equation If we want Spring Constant, cover up Spring

How to use the Spring equation If we want Spring Constant, cover up Spring Constant Force ÷ Spring X Extension Constant We divide Force by the Extension

How to use the Spring equation If we want Extension, cover up Extension Force

How to use the Spring equation If we want Extension, cover up Extension Force ÷ Spring Extension X Constant We divide Force by the Extension

Questions If a bungee rope has a spring constant of 60 N/m. How far

Questions If a bungee rope has a spring constant of 60 N/m. How far will it extend (stretch) if a person who weighs 600 N (mass = 60 Kg) is placed on it?

How to use the Spring equation If we want Extension, cover up Extension Force

How to use the Spring equation If we want Extension, cover up Extension Force ÷ Spring Extension X Constant We divide Force by the Extension

Questions If a bungee rope has a spring constant of 60 N/m. How far

Questions If a bungee rope has a spring constant of 60 N/m. How far will it extend (stretch) if a person who weighs 600 N (mass = 60 Kg) is placed on it? Extension= Force ÷ Spring Constant =600 N ÷ 60 N/m =10 m Force ÷ Spring Extension X Constant

Questions A bungee rope has a spring constant of 50 N/m. How much must

Questions A bungee rope has a spring constant of 50 N/m. How much must a person weigh in N if it we want it to extend (stretch) 20 m?

How to use the Spring equation If we want Force, cover up Force ÷

How to use the Spring equation If we want Force, cover up Force ÷ Spring Constant X Extension We multiply the Spring Constant by the Extension

Questions If a bungee rope has a spring constant of 50 N/m. How much

Questions If a bungee rope has a spring constant of 50 N/m. How much must a person weigh in N if it we want it to extend (stretch) 20 m? Force = Extension x Spring Constant = 20 m x 50 N/m = 1000 N Force (100 Kg) ÷ Spring X Extension Constant

Practice Questions 1. If a bungee rope has a spring constant of 5 N/m.

Practice Questions 1. If a bungee rope has a spring constant of 5 N/m. How far will it extend (stretch) if a person who weighs 300 N (mass = 30 Kg) is placed on it? e = 60 m 2. If a bungee rope has a spring constant of 15 N/m. How much must a person weigh in N if it we want it to extend (stretch) 10 m? F = 150 N 3. What is the spring constant of a bungee rope in N/m if a person weigh 200 N if it we want it to extend (stretch) 20 m? k = 10 N/m
