Forces and Hooke's Law Quiz

What are the three effects a force can have on an object?

• Change its size, temperature, and color

• Change its temperature, shape, and movement

• Change its size, shape, and movement

• Change its color, size, and shape

How is acceleration related to force and mass?

• Acceleration is the product of force and mass

• Acceleration is the quotient of force and mass

• Acceleration is the sum of force and mass

• Acceleration is the difference between force and mass

What is the unit of force in the context of physics?

• Pascals

• Watts

• Joules

• Newtons

What is the term used to describe how much longer a spring gets when a force is applied?

• Deflection

• Extension

• Compression

• Tension

If a spring is originally 3 cm long and is stretched to 9 cm, what is the extension?

• 12 cm

• 6 cm

• 9 cm

• 3 cm

According to Hooke's Law, what is the relationship between force and extension?

• Force is inversely proportional to extension

• Force is directly proportional to extension

• Force is equal to the square of extension

• Force is unrelated to extension

What does the spring constant (K) represent in Hooke's Law?

• The maximum extension possible

• The proportionality constant between force and extension

• The amount of force applied

• The original length of the spring

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

• It changes color

• It shrinks in size

• It becomes permanently deformed

• It returns to its original shape

What is the term for the point at which a spring will no longer return to its original shape?

• Breaking point

• Compression point

• Elastic limit

• Yield point

What is the consequence of stretching a spring too far?

• It will change its color

• It will become shorter

• It will break or snap

• It will become more elastic
