Force and Extension Experiments: Analyzing Results and Understanding the Relationship

The video tutorial covers force and extension experiments, focusing on analyzing results by plotting a graph of extension against force. It explains how to determine scales for the graph, plot data points, and draw a line of best fit. The concept of direct proportionality is explored, showing that doubling the force doubles the extension. The tutorial also explains how to calculate the spring constant and concludes with a summary of the experiments.

What is the maximum force value used on the horizontal axis in the experiment?

• 3 Newtons

• 6 Newtons

• 12 Newtons

• 9 Newtons

When plotting points, how should values be approximated?

• Plot on a grid line or halfway between grid lines

• Always round down to the nearest grid line

• Always round up to the nearest grid line

• Plot exactly as calculated

What does a directly proportional relationship imply in the context of force and extension?

• Doubling the force halves the extension

• Force remains constant as extension increases

• Force and extension are unrelated

• Doubling the force doubles the extension

How is the ratio of force to extension expressed for the spring in the experiment?

• 0.023 Newtons per millimeter

• 0.023 Newtons per centimeter

• 23 Newtons per millimeter

• 23 Newtons per centimeter

What is the general formula for the relationship between force and extension in springs?

• F = m * a

• F = k / e

• F = e / k

• F = k * e

What is the spring constant typically measured in?

• Newtons per meter

• Newtons per centimeter

• Newtons per millimeter

• Newtons per kilometer

If a force of 0.023 Newtons extends the spring by 1 millimeter, how much force is needed to extend it by 1 meter?

• 2300 Newtons

• 23000 Newtons

• 23 Newtons

• 230 Newtons
