Spring Dynamics and Forces

The video tutorial explains a spring-mass system where a block is attached to a spring and stretched. It covers the calculation of force using Hooke's Law and the resulting acceleration using Newton's second law. The tutorial also discusses the importance of springs in engineering and their applications in real-world structures.

What is the mass of the block attached to the spring?

• 0.500 kg

• 0.600 kg

• 0.700 kg

• 0.800 kg

What is the maximum displacement of the block from its equilibrium position?

• 0.140 meters

• 0.120 meters

• 0.130 meters

• 0.100 meters

What is the force constant of the spring in the problem?

• 140 N/m

• 130 N/m

• 150 N/m

• 120 N/m

What is the equilibrium position of a spring?

• The position where the spring is fully stretched

• The position where the spring is fully compressed

• The position where the spring is at maximum displacement

• The position where the spring is neither compressed nor stretched

Why are springs important in engineering and science?

• They help in understanding the dynamics of various structures

• They are used only in toys

• They are used only in mechanical clocks

• They are not important in engineering

What does Hooke's Law state about the force exerted by a spring?

• Force is inversely proportional to the displacement

• Force is inversely proportional to the spring constant

• Force is directly proportional to the displacement

• Force is directly proportional to the mass of the block

What is the calculated force exerted by the spring on the block?

• 28.2 N to the left

• 16.9 N to the right

• 16.9 N to the left

• 28.2 N to the right

How is the acceleration of the block calculated?

• By adding the force and the mass

• By multiplying the force by the mass

• By dividing the force by the displacement

• By dividing the force by the mass

What is the direction of the acceleration of the block when released?

• To the right

• To the left

• Downwards

• Upwards

What is the calculated acceleration of the block?

• 28.2 m/s² to the left

• 28.2 m/s² to the right

• 16.9 m/s² to the right

• 16.9 m/s² to the left
