Understanding Spring Mechanics

The video tutorial explores the relationship between spring extension and force, demonstrating how to measure force using weights and calculate the spring constant. It includes data collection and analysis, plotting graphs, and understanding the significance of the spring constant. Real-world applications, such as bows and hockey sticks, are discussed to illustrate the linear relationship between force and extension.

What is the equilibrium position of a spring?

• When the spring is fully extended

• When the spring is vibrating

• When no weight is added to the spring

• When the spring is fully compressed

Why is it important to settle the spring after adding weights?

• To increase the spring's extension

• To make the spring heavier

• To stop the spring from vibrating

• To decrease the spring's force

How is the force on the spring measured in this experiment?

• By observing the spring's color change

• By measuring the spring's length

• By calculating the weight added

• By using a force meter

What is the mass increment used in the data collection process?

• 10 grams

• 100 grams

• 20 grams

• 50 grams

What is plotted on the x-axis of the graph?

• Spring extension

• Spring force

• Weight of the spring

• Vibration frequency

How is the spring constant calculated from the graph?

• By measuring the slope directly

• By calculating the rise over run

• By calculating the run over rise

• By finding the area under the curve

What is the traditional unit for spring constant?

• Newtons per centimeter

• Milli newtons per meter

• Newtons per meter

• Grams per meter

What does a spring constant of 300 newtons per meter mean for a bow?

• It requires 300 newtons to break the bow

• It requires 300 newtons to extend the bow by one meter

• It requires 300 newtons to vibrate the bow

• It requires 300 newtons to compress the bow by one meter

What does a higher flex rating in a hockey stick indicate?

• The stick is more flexible

• The stick is less durable

• More effort is needed to bend the stick

• Less effort is needed to bend the stick

If a hockey stick has a flex rating of 85, how much force is needed to flex it by four inches?

• 170 pounds

• 425 pounds

• 85 pounds

• 340 pounds
