Simple Harmonic Motion - Force, Acceleration, and Velocity at 3 Positions

The video tutorial explains simple harmonic motion using a horizontal mass-spring system. It covers the positions of maximum displacement and rest, discussing the magnitudes of velocity, acceleration, and spring force at these points. The tutorial highlights that velocity is zero at maximum displacement and maximum at the equilibrium position. Hooke's Law is used to explain spring force, and the relationship between spring force and acceleration is explored. The video concludes by emphasizing that simple harmonic motion is not uniformly accelerated, urging students to remember this distinction.

What happens to the velocity of the mass at positions one and three in simple harmonic motion?

• It reaches its maximum value.

• It is negative.

• It is constant.

• It is zero.

According to Hooke's law, what is the relationship between the spring force and displacement?

• The spring force is equal to the displacement.

• The spring force is directly proportional to the displacement.

• The spring force is inversely proportional to the displacement.

• The spring force is independent of the displacement.

What is the term used to describe the maximum displacement from the equilibrium position?

• Period

• Amplitude

• Frequency

• Wavelength

How does the acceleration of the mass at position two compare to positions one and three?

• It is less at position two.

• It is the same at all positions.

• It is zero at position two.

• It is greater at position two.

Why can't uniformly accelerated motion equations be used for simple harmonic motion?

• Because the acceleration is zero.

• Because the acceleration is constant.

• Because the velocity is constant.

• Because the acceleration is not constant.
