Physics Force And Extension

Question 1

What is the aim?

Answer 1

To determine the relationship between force and extension for a spring

Question 2

What happens when a force is applied to a spring?

Answer 2

It caused it to extend, increasing the force increases the extension

Question 3

What does this practical investigate

Answer 3

How the investigates how the extension varies with applied force for a spring, to determine if it obey’s Hooke’s law

Question 4

Independent variable

Answer 4

Applied force

Question 5

Dependent variable

Answer 5

Extension of spring

Question 6

Control variable

Answer 6

Same spring

Question 7

Hooke’s law in simple terms

Answer 7

Apply a force to a spring, then the force stretches spring

Question 8

What is the relationship between the force applied to a spring and its extension according to Hooke’s law?

Answer 8

They are directly proportional

Question 9

Which of the following is unit for the spring constant?

Answer 9

N/m

Question 10

How is the extension of the spring calculated?

Answer 10

Extension= length - original length
