Hooke's Law links the extension of a spring to the force acting on it. But, it fails when a material reaches its:

• breakdown

• elastic limit

• end of tether

• fracture stress

What is the best description of the relationship shown in this graph?

• In this graph, the relationship between force and extension is linear.

• In this graph, the relationship between force and extension is non-linear.

• In this graph, the relationship between force and extension is directly proportional.

• In this graph, there is no relationship between force and extension.

Below is the list of what a force can do. Which one is related to the behaviour of a spring when we hang a mass on it?

• A force can change the speed

• A force can change the direction

• A force can change the shape of an object

The length of a spring is 10 cm. When 1 N object is hung onto it, the length becomes 11 cm. What is the extension of the spring?

• 1 cm

• -1 cm

• 1 m

• -1 m

When you stretch it it will become back to its original form

• Brittleness

• Elasticity

• Malleability

• Ductility

Its turn back to its original form

Once you let go of a rubber band, it will easily go back to its relaxed state. The property observed is…

A metal rod that after being stretched or compressed lengthwise returns to its original length is an example of...

What is the formula for calculating the elastic potential energy stored in a spring?
