MULTIPLE CHOICE QUESTION
30 sec • 1 pt
the mass of the object.
the displacement of the spring.
the length of the spring.
the volume of the object.
Answer explanation
According to Hooke's law, the force exerted by a spring is directly proportional to the displacement of the spring from its equilibrium position, making 'the displacement of the spring' the correct choice.

In any system in simple harmonic motion, the restoring force acting on the mass in the system is proportional to
displacement.
the length of a pendulum.
the mass.
frequency.
Answer explanation
In simple harmonic motion, the restoring force is always proportional to the displacement from the equilibrium position. This means that as the object moves further from equilibrium, the force acting to bring it back increases.

The spring constant in a given oscillating mass-spring may be changed by
increasing the mass.
decreasing the mass.
decreasing the initial displacement.
none of the above
Answer explanation
The spring constant is a property of the spring itself and is not affected by the mass or displacement. Therefore, changing the mass or displacement does not change the spring constant, making 'none of the above' the correct choice.

In an oscillating mass-spring system, the velocity of the mass is greatest when the mass is
at the point of maximum displacement.
halfway between the equilibrium point and maximum displacement.
at the point where acceleration is greatest.
at the equilibrium point.
Answer explanation
In an oscillating mass-spring system, the velocity is greatest at the equilibrium point because the mass has maximum kinetic energy there, while at maximum displacement, the velocity is zero.

The period of a pendulum may be decreased by
shortening its length.
increasing the mass of the bob.
moving its equilibrium point.
decreasing the mass of the bob.
Answer explanation
The period of a pendulum is determined by its length. Shortening the length decreases the period, while changing the mass or moving the equilibrium point does not affect the period significantly.

MULTIPLE CHOICE QUESTION
30 sec • 1 pt
As the swinging bob of a pendulum moves farther from its equilibrium position, the pendulum's _____ increases.
frequency
mass
restoring force
length
Answer explanation
As the pendulum bob moves away from its equilibrium position, the distance from equilibrium increases, leading to a greater restoring force acting to bring it back. Thus, the restoring force increases.

The gravitational potential energy of the bob of a swinging pendulum is at its maximum when the bob is at
maximum displacement.
the equilibrium point.
the center of its swing.
minimum displacement.
Answer explanation
The gravitational potential energy of the bob is highest at maximum displacement, where it is farthest from the equilibrium point. At this position, the bob has the greatest height, resulting in maximum potential energy.
