Experiment to Investigate the Relationship Between Extension and Applied Force on a Spring

The video tutorial explains an experiment to investigate the relationship between the force applied to a spring and its extension. It outlines the procedure, including suspending the spring, measuring its extension, and adding masses. The experiment's variables are defined, and results are plotted on a graph to determine the spring constant. The relationship between force and extension is shown to be proportional up to a certain limit, and the spring constant is calculated using the graph.

What is the first step in setting up the experiment to measure spring extension?

• Add a 100 gram mass to the spring

• Suspend the spring from a fixed point

• Place a ruler horizontally behind the spring

• Calculate the spring constant

In the experiment, what is the independent variable?

• The type of spring used

• The force applied to the spring

• The extension of the spring

• The number of lessons conducted

What is the relationship between force and extension up to the limit of proportionality?

• Force is inversely proportional to extension

• Force is directly proportional to extension

• Force is exponentially related to extension

• Force is unrelated to extension

What does the spring constant (k) represent in the equation F = kE?

• The force required to stretch the spring by 1 meter

• The length of the spring

• The force required to compress the spring by 1 meter

• The mass of the spring

If a force of 6 Newtons results in an extension of 0.15 meters, what is the spring constant?

• 50 Newtons per meter

• 40 Newtons per meter

• 30 Newtons per meter

• 20 Newtons per meter
