Which of the following best describes Hooke's Law in physics?

• The law that states that energy cannot be created or destroyed, only converted from one form to another.

• The law that describes the relationship between an object's mass, acceleration, and the net force acting on it.

• The law that governs the behavior of ideal gases at constant temperature, stating that the volume of a gas is inversely proportional to its pressure.

• The law that states the force required to extend or compress a spring is directly proportional to the displacement of the spring from its equilibrium position.

A weight of 18 newtons is hung on a spring which has an unloaded length of 24 cm. What is the value of the spring's spring constant?

• 6 N/m

• 7.5 N/m

• 75 N/m

• 432 N/m

A 0.40 kg object is attached to a spring with spring constant of 160 N/m so that the object is allowed to move on a horizontal frictionless surface. The object is released from rest when the spring is compressed 0.15 m. Find its maximum acceleration.

• 60 m/s^2

• 45 m/s^2

• 25 m/s^2

• 54 m/s^2

A spring is hung from a ceiling, and an object attached to its lower end stretches the spring by a distance of 5.00 cm from its un-stretched position when the system is in equilibrium. If the spring constant is 47.5 N/m, determine the mass of the object

• 0.242 kg

• 2.42 kg

• 0.245 kg

• 2 kg East

A spring has a spring constant of 65.5 N/m and it is stretched with a force of 15.3 N. How far will it stretch?

• 21 cm

• 22 cm

• 23 cm

• 24 cm

When a force of 2.5 N is attached to a spring, it's length increases by 16 cm. What is the spring constant of the spring?

• 14.3 N/m

• 15.2 N/m

• 15 .6 N/M

• 18.5 N/M

The point at which a spring is permanently deformed is called the

• resultant force

• restoration limit

• rarefaction force

• elastic limit
