Understanding Spring Behavior Through Force and Extension

The video tutorial explains the behavior of springs under tensile and compressive forces. It introduces key terminology related to springs and demonstrates how to measure the extension of a spring using a mass hanger. The concept of Hook's Law is explained, showing the proportional relationship between force and extension, and introducing the spring constant. Different springs have varying stiffness, which is represented by their spring constants. The video also covers how to interpret graphs of force versus extension, highlighting the significance of the gradient as the spring constant.

What is a tensile force?

• A force that breaks a spring

• A force that pulls and extends a spring

• A force that rotates a spring

• A force that compresses a spring

What happens to a spring when a compressive force is applied?

• It remains unchanged

• It gets shorter

• It rotates

• It gets longer

How do you measure the extension of a spring?

• By subtracting the original length from the extended length

• By measuring the final length only

• By measuring the original length only

• By adding the original and extended lengths

What does Hook's Law state?

• The extension is constant regardless of the force applied

• The extension is proportional to the force applied, within the elastic limit

• The extension is proportional to the mass of the spring

• The extension is inversely proportional to the force applied

What symbol is used to represent extension in Hook's Law?

• F

• K

• X

• E

What does the spring constant (K) indicate?

• The color of the spring

• The temperature of the spring

• How much a spring extends when a force is applied

• The weight of the spring

How do different springs react to the same force?

• They all extend the same amount

• They extend differently based on their spring constant

• They do not extend at all

• They break under the same force

What does the gradient of a force-extension graph represent?

• The mass of the spring

• The spring constant

• The temperature of the spring

• The color of the spring

If a spring is described as 'stiff', what does this imply about its spring constant?

• It has no spring constant

• It has a high spring constant

• It has a variable spring constant

• It has a low spring constant

What happens to the extension of a spring as more force is applied, according to Hook's Law?

• The extension decreases

• The extension increases

• The extension remains the same

• The extension becomes zero
