Physics of Forces and Elasticity Quiz

What is required to squash a stationary object?

• One force from any direction

• No force is needed

• Two forces from the same side

• Two forces from opposite sides

What happens to an elastic object when the force is removed?

• It returns to its original shape

• It breaks

• It remains deformed

• It changes color

Which of the following is an example of an inelastic object?

• A rubber band

• A spring

• Blu-tac

• A metal rod

According to Hooke's Law, what happens when you double the force applied to a spring?

• The extension triples

• The extension doubles

• The extension halves

• The spring breaks

What is the first step in the experiment to test Hooke's Law?

• Apply a force to the spring

• Measure the original length of the spring

• Record the results

• Attach a mass to the spring

How do you calculate the extension of the spring in the experiment?

• By multiplying the original length by the force

• By dividing the new length by the original length

• By adding the original and new lengths

• By subtracting the original length from the new length

What is the independent variable in the Hooke's Law experiment?

• The type of spring used

• The extension of the spring

• The temperature of the room

• The force applied

What does a straight line through zero on a force vs. extension graph indicate?

• The spring is broken

• The spring does not obey Hooke's Law

• The spring obeys Hooke's Law

• The spring is inelastic

What happens when a spring is overstretched?

• It becomes more elastic

• It becomes shorter

• It changes color

• It loses its elastic properties

What is a control variable in the Hooke's Law experiment?

• The time taken

• The extension measured

• The type of spring used

• The weight applied
