Simple Harmonic Motion Concepts

The video tutorial explains simple harmonic motion (SHM), addressing common misconceptions and providing a clear definition. It uses examples like pendulums and mass-spring systems to illustrate SHM. The tutorial covers the relationship between force, acceleration, and displacement, and provides graphical representations of SHM. It also discusses energy conservation in SHM, using graphs to show potential and kinetic energy changes over time.

What is the primary difference between simple harmonic motion and periodic motion?

• Periodic motion requires a pendulum, while SHM does not.

• Periodic motion is always linear, while SHM is not.

• SHM is always faster than periodic motion.

• SHM involves acceleration proportional to displacement, while periodic motion does not.

In the context of SHM, what does the negative sign in the acceleration equation signify?

• The acceleration is always decreasing.

• The displacement is negative.

• The motion is slowing down.

• The acceleration is in the opposite direction to displacement.

How does the force act in relation to displacement in a pendulum undergoing SHM?

• Force acts in the same direction as displacement.

• Force acts perpendicular to displacement.

• Force acts opposite to displacement.

• Force does not affect displacement.

What happens to the potential energy of a mass on a spring at maximum displacement?

• It is equal to kinetic energy.

• It is zero.

• It is at its maximum value.

• It is at its minimum value.

At what point is the kinetic energy of a mass on a spring at its maximum?

• At the end of motion.

• At equilibrium.

• At maximum displacement.

• At the start of motion.

What is the significance of the equilibrium position in SHM?

• It is where kinetic energy is zero.

• It is where kinetic energy is maximum.

• It is where potential energy is maximum.

• It is where the object changes direction.

What does the graph of total energy versus displacement in SHM look like?

• A straight line.

• A zigzag pattern.

• A parabolic curve.

• A sinusoidal wave.

How does potential energy change over time in SHM?

• It remains constant.

• It oscillates between maximum and zero.

• It decreases exponentially.

• It increases linearly.

What is the relationship between kinetic and potential energy in SHM?

• They are inversely proportional.

• One is always double the other.

• They are always equal.

• Their sum is constant.

In SHM, what happens to the total energy over time?

• It increases.

• It decreases.

• It fluctuates randomly.

• It remains constant.
