Year 10 - Hooke's Law investigation

How can you measure the extension of a spring accurately?

• • By using a ruler to measure the length of the spring.

• • By using a force meter to measure the force applied.

• • By using a stopwatch to measure the time it takes for the spring to return to its original length.

• • By using a vernier caliper to measure the change in length of the spring.

What is the independent variable in this investigation?

• Extension

• Force applied to the spring

• Spring Constant

• Mass attached to the spring

What is the dependent variable in this investigation:

• Extension of the Spring

• Original length of the spring

• Mass attached to spring

• Force

In the same experiment, a control variable would be:

• The type of spring used

• The length of the spring used

• The temperature of the room

• All of the above

What are some factors that can affect the spring constant of a spring?

• The thickness of the wire used to make the spring.

• The length of the spring.

• The material the spring is made from.

• All of the above.
