Understanding Spring Constants and Forces

This video tutorial explains Hooke's Law, which states that the force needed to stretch or compress a spring is proportional to the distance it is stretched. The relationship is represented by the equation F = K x S, where F is the force, K is the spring constant, and S is the distance. An example problem is solved to find the spring constant and determine how much a spring stretches under a different force. The solution is verified to ensure it makes sense.

What does Hooke's Law state about the relationship between force and distance in a spring?

• Force is inversely proportional to distance.

• Force is directly proportional to distance.

• Force is equal to the square of the distance.

• Force is unrelated to distance.

In the equation F = K x S, what does 'K' represent?

• The weight of the spring.

• The spring constant.

• The distance the spring is stretched.

• The force applied to the spring.

If a 10-pound force stretches a spring by half a foot, what is the spring constant?

• 10/6

• 3/5

• 6/10

• 5/3

What is the simplified form of the spring constant if it is initially calculated as 10/6?

• 5/3

• 3/2

• 2/3

• 1/2

How many inches will a 6-pound force stretch the spring?

• 4 inches

• 5 inches

• 3.6 inches

• 6 inches

What is the reciprocal of 5/3 used in the calculation?

• 1/5

• 1/3

• 3/5

• 5/3

How is 18/5 inches expressed as a mixed number?

• 3 and 3/5 inches

• 4 and 1/5 inches

• 2 and 4/5 inches

• 5 and 3/5 inches

What is the decimal equivalent of 3 and 3/5 inches?

• 3.7 inches

• 3.6 inches

• 3.8 inches

• 3.5 inches

Why does it make sense that a 6-pound weight stretches the spring less than a 10-pound weight?

• Because the spring is broken.

• Because less force results in less stretch.

• Because the spring constant changes with weight.

• Because 6 pounds is heavier than 10 pounds.

What is the relationship between the force applied and the stretch of the spring?

• Stretch is constant regardless of force.

• Force does not affect stretch.

• More force results in less stretch.

• More force results in more stretch.
