Understanding Spring Dynamics and Forces

The video tutorial explains the behavior of a loaded spring, focusing on the relationship between force and extension. It introduces the concept of restoring force and the spring constant, represented by the equation F = -kx. The tutorial further derives the equations of motion for a spring system, including the acceleration and angular frequency. Finally, it explains how to calculate the period of spring motion using the derived equations.

What happens to a spring when a small force is applied?

• It compresses significantly.

• It extends slightly.

• It breaks.

• It remains unchanged.

In the context of springs, what does the term 'extension' refer to?

• The twisting of the spring.

• The compression of the spring.

• The lengthening of the spring.

• The breaking of the spring.

What is the direction of the restoring force in a spring?

• No specific direction.

• Perpendicular to the extension.

• Opposite to the extension.

• Same as the extension.

What does the equation F = -kx represent?

• The force of friction.

• The force of tension.

• The force of gravity.

• The restoring force in a spring.

How is the spring constant 'k' defined?

• Mass per unit extension.

• Restoring force per unit extension.

• Extension per unit force.

• Force per unit mass.

What does a high value of the spring constant indicate?

• A broken spring.

• A light spring.

• A compressed spring.

• A heavy spring.

Which equation represents the relationship between force and acceleration in a spring system?

• F = m * d²x/dt²

• F = kx

• F = -kx

• F = ma

What is the formula for the period of motion in a spring system?

• T = 2πm/k

• T = 2πk/m

• T = 2π√(m/k)

• T = 2π√(k/m)

How does the mass of a body affect the period of motion in a spring system?

• It has no effect.

• A larger mass increases the period.

• A larger mass decreases the period.

• It only affects the amplitude.

What is the relationship between omega (ω) and the spring constant (k) and mass (m)?

• ω = k/m

• ω = √(m/k)

• ω = m/k

• ω = √(k/m)
