Hooke's law refresher quiz

What force causes a spring to extend when a mass is attached to it?

• Tensile force

• Compressive force

• Gravitational force

• Frictional force

What happens to a spring when the mass causing it to extend is removed, assuming it has not passed the elastic limit?

• It contracts beyond its natural length

• It remains extended

• It breaks

• It returns to its natural length

Which of the following is NOT an example of a tensile force?

• Hanging a mass on a spring

• Pulling on a guitar string

• Pushing a car

• Pulling back on a bow and arrow

What is the relationship between the force applied to a spring and its extension according to Hooke's Law?

• Exponentially related

• No relationship

• Directly proportional

• Inversely proportional

What does the spring constant (k) represent?

• The mass of the spring

• The length of the spring

• The stiffness of the spring

• The color of the spring

What are the units of the spring constant (k)?

• Newtons per meter (N/m)

• Kilograms (kg)

• Meters (m)

• Meters per second squared (m/s^2)

What happens when a spring is stretched beyond its elastic limit?

• It becomes stiffer

• It remains permanently deformed

• It returns to its natural length

• It loses all its mass

What is the force needed to extend a spring with a spring constant of 5 Newtons per meter by 0.1 meters?

• 0.5 Newtons

• 5 Newtons

• 10 Newtons

• 0.05 Newtons

What type of force is applied to squash a spring?

• Compressive force

• Gravitational force

• Magnetic force

• Tensile force

What is the effect of removing a compressive force from a spring?

• The spring remains squashed

• The spring extends beyond its natural length

• The spring breaks

• The spring returns to its original length
