Vector Quantities and Spring Mechanics Quiz

What distinguishes a vector quantity from a scalar quantity?

• Only magnitude
• Only direction
• Both magnitude and direction
• Neither magnitude nor direction

In the context of Hooke's Law, what does the spring constant (k) represent?

• The initial length of the spring
• The spring's weight capacity
• A measure of the spring's stiffness
• The total extension of the spring

Which of the following is NOT a vector quantity?

• Velocity
• Temperature
• Acceleration
• Momentum

What is the limit of proportionality in a spring extension experiment?

• The point where the spring breaks
• The maximum weight the spring can hold
• The point where the relationship between weight and extension becomes non-linear
• The initial length of the spring

Why do black surfaces typically absorb more radiation compared to white surfaces?

• Black surfaces have more molecules
• Black surfaces have different molecular structure
• Black surfaces have lower reflectivity
• Black surfaces are always hotter

How is the spring constant (k) calculated in an experimental graph?

• Total weight divided by extension
• Change in length divided by change in weight
• Initial length multiplied by weight
• Maximum extension divided by initial length

Which vector quantity describes an object's change in position over time?

• Acceleration
• Velocity
• Force

In a spring extension experiment, what does the y-intercept of the graph represent?

• Spring constant
• Maximum weight
• Initial length of the spring
• Total extension

What factor most influences a surface's ability to emit radiation?

• Size
• Shape
• Weight

Which scientific principle explains the linear relationship between weight and spring extension?
