Physics Quiz 2.5

Which term refers to the position where the net force on a spring is zero?

• Maximum position

• Equilibrium position

• Compression point

• Elastic limit

What does the negative sign in Hooke’s Law Fspring = -k(Δx) indicate?

• The force is always positive

• The restoring force is in the same direction as the displacement

• The restoring force is always in the opposite direction of the applied force

• The spring constant is negative

A student wants to determine the spring constant (k) of a spring experimentally. Which of the following should they do?

• Measure the mass of the spring only

• Measure the force applied and the amount of stretch/compression

• Measure the temperature of the spring

• Measure the color of the spring

Why are springs considered elastic objects?

• They can conduct electricity

• They store mechanical energy and return to their original shape after being stretched or compressed

• They are made of plastic

• They always stay stretched

A student observes a spring moving back and forth after being pulled. Which key term best describes this motion, and what does it indicate about the system?

• Displacement; the spring is at rest

• Oscillation; the spring is undergoing repeated motion about equilibrium

• Restoring Force; the spring is not moving

• Spring Constant; the spring is being stretched
