Question 0

You can tell if an object obeys hookes law on a graph

Answer 0

If it is directly proportional (straight line through the origin)

Question 1

Hookes law

Answer 1

Load is directly proportional to the extension provided that you dont go beyond the elastic limit

Question 2

If an object goes beyond its elastic limit…

Answer 2

• weakens
• behaves plastically
• permanently deformed
• on a graph curves to a horizontal line

Question 3

What is meant by an object behaving plastically?

Answer 3

Doesnt return to its normal shape ie bluetac

Question 4

Elastic band graph is … Proportional

Answer 4

Not directly

Question 5

An elastic band doesnt behave…

Answer 5

Plastically as it returns to its original shape

Question 6

Do elastic bands obey hookes law

Answer 6

No as the graph doesnt show a straight line (even though it goes through the origin)

Question 7

Elastic band graphs go like a … As when stretched it goes from weak to strong

Answer 7

S
