Simple Harmonic Motion Concepts

The video tutorial explains the simple harmonic motion of a mass on a vertical spring, comparing it to a horizontal spring. It covers the equilibrium position, forces acting on the system, and applies Newton's second law to derive the simple harmonic equation. The presenter, a student, aims to improve their understanding and teaching skills while helping viewers.

What is the main focus of this video tutorial?

• Gravitational force on a spring

• Newton's laws of motion

• Simple harmonic motion for a mass on a horizontal spring

• Simple harmonic motion for a mass on a vertical spring

What happens to the spring when a mass is attached to it?

• The spring breaks

• The spring remains unchanged

• The spring extends

• The spring compresses

In the equilibrium position, what is the relationship between the gravitational force and the spring force?

• Gravitational force is unrelated to spring force

• Gravitational force is equal to spring force

• Gravitational force is less than spring force

• Gravitational force is greater than spring force

What is the significance of the negative sign in Hooke's law?

• Indicates force is zero

• Indicates force is constant

• Indicates force is in the opposite direction to displacement

• Indicates force is in the same direction as displacement

What is the role of the spring constant (k) in the system?

• It determines the length of the spring

• It determines the stiffness of the spring

• It determines the gravitational force

• It determines the mass of the spring

When the mass is displaced downward, what additional force is considered?

• Resultant force

• Tension force

• Frictional force

• Magnetic force

What law is applied to derive the simple harmonic motion equation?

• Hooke's law

• Newton's third law

• Newton's second law

• Newton's first law

What is the expression for the resultant force when the mass is displaced?

• ma = mg

• ma = kx - mg

• ma = mg - kx

• ma = mg + kx

What does omega squared (ω²) represent in the simple harmonic motion equation?

• m/k

• k/m

• m*g

• k*x

How does the simple harmonic motion equation for a vertical spring compare to that of a horizontal spring?

• They are the same

• Vertical is more complex

• Horizontal is more complex

• They are different
