Question

hookes law and youngs modulus - student worksheet
this worksheet will help you understand the basics of hookes law and youngs modulus. read the hints and formulas provided, then answer the questions in the space below each one.
key definitions:
hookes law: this law says that the stretch (or compression) of a spring is directly related to the force applied to it. the formula is f = k * x
youngs modulus: this tells us how stiff a material is. it compares how much a material stretches to the force applied. the formula is y=(f l)/(a δl)
multiple choice questions (choose the correct answer):

1. what does hookes law describe?

• a. how fast a spring moves
• b. how much a spring stretches
• c. the color of a spring
• d. the weight of a spring

1. what is the formula for hookes law?

• a. f = m * a
• b. f = k * x
• c. e = mc²
• d. v = i * r

1. what does k represent in hookes law?

• a. force
• b. stretch
• c. spring constant
• d. mass

Explanation:

1. Hooke's Law describes the relationship between the force applied to a spring and its stretch or compression. So the answer to question 1 is based on this definition.
2. The formula for Hooke's Law is given as \(F = k\times x\) in the provided key - definitions, which answers question 2.
3. In Hooke's Law \(F = k\times x\), \(k\) is the spring constant that characterizes the stiffness of the spring, answering question 3.

Answer:

1. B. How much a spring stretches
2. B. \(F = k\times x\)
3. C. Spring constant
