Robert Hooke and Uses of Elastic Objects

Don’t worry if you get a question wrong! Forgetting is an important step in learning. We will recap next lesson.

Q1.For an object with a larger spring constant, the force required to stretch it would be

1/9

Q2.This means more work is done so the energy stored in the spring is

2/9

Q3.For an object with a smaller spring constant the force required to stretch or compress it is

3/9

Q4.This means less work is done so the energy stored in the spring is

4/9

Q5.In a bow and arrow, when we let go of the string, the energy is transferred from the elastic potential store to the

5/9

Q6.Use Hooke's Law: Force = Spring constant x extension to calculate the force required to stretch a 5 N/m spring to 2 m

6/9

Q7.Use Hooke's Law: Force = Spring constant x extension to calculate the force required to stretch a 0.5 N/m spring to 4 m

7/9

Q8.Use Hooke's Law: Force = Spring constant x extension to calculate the extension produced if a force of 10 N is exerted on a spring with a constant of 5 N/m

8/9
