REQUIRED PRACTICAL- Hookes law

Question 1

WHAT IS THE AIM OF THE PRACTICAL?

Answer 1

To determine relationship between force and extension of a spring

Question 2

WHAT EQUIPMENT WILL YOU NEED?

Answer 2

-Clamp stand
-G- clamp
-Meter ruler
-Spring
-Newton weights

Question 3

WHAT IS THE INDEPENDENT VARIABLE?

Answer 3

the force applied to the spring

Question 4

WHAT IS THE DEPENDENT VARIABLE?

Answer 4

Extension of spring

Question 5

WHAT IS THE CONTROL VARIABLE?

Answer 5

using the same spring

Question 6

HOW WOULD YOU CARRY OUT HOOKES LAW PRACTICAL?

Answer 6

1) Set up equipment and measure the original length of the spring
2) Start by adding newton weights and measuring the length of the spring after the weight has been added.
3) Take extension length and subtract original length to get extension
4) PLOT GRAPH

Question 7

WHAT IS SPRING CONSTANT?

Answer 7

a measure of stiffness of the spring

Question 8

WHAT SHOULD GRAPH FOR HOOKES LAW SHOW?

Answer 8

The force applied is directly proportional to extension up to its Limit of proportionality where the spring becomes elastically deformed
