Simple Harmonic Motion

What is Simple Harmonic Motion (SHM)?

• A type of motion where an object moves in a straight line without oscillating.

• A type of periodic motion where an object oscillates back and forth around an equilibrium position, with a restoring force proportional to the displacement from that position.

• A motion that occurs only in circular paths without any restoring force.

• A random motion that does not follow any predictable pattern.

What is amplitude in the context of SHM?

• The total energy of the oscillating object.

• The frequency of the oscillation.

• The maximum displacement of the object from its equilibrium position during oscillation.

• The time taken to complete one full cycle of oscillation.

What is the formula for the period of a simple pendulum?

• T = 2π√(L/g)

• T = L/g

• T = g/2π√(L)

• T = 2πL/g

What is the effect of increasing the length of a pendulum on its period?

• Increasing the length of a pendulum decreases its period.

• Increasing the length of a pendulum has no effect on its period.

• Increasing the length of a pendulum increases its period.

• Increasing the length of a pendulum makes it swing faster.

How does the mass of an object affect the period of a spring in SHM?

• The mass increases the period of the spring in SHM.

• The mass decreases the period of the spring in SHM.

• The mass does not affect the period of a spring in SHM; the period is independent of mass.

• The mass only affects the amplitude of the spring in SHM.

What is the formula for the total mechanical energy in SHM?

• E = 1/2 k A²

• E = k A

• E = 1/2 m v²

• E = mgh

What is the maximum velocity of a pendulum?

• At the highest point in the swing

• At the lowest point in the swing

• Halfway through the swing

• When it is stationary

What is the restoring force in SHM?

• The force that acts to bring the object back to its equilibrium position, proportional to the displacement from that position.

• The force that acts to increase the object's speed as it moves away from equilibrium.

• The force that opposes the motion of the object regardless of its position.

• The force that acts only when the object is at rest.

What is the phase of an oscillating object in SHM?

• The phase describes the position of the object in its cycle of motion at a specific time, often measured in radians.

• The phase refers to the speed of the object during oscillation.

• The phase indicates the amplitude of the oscillation at any given time.

• The phase is the total energy of the oscillating system.

What is the significance of damping in SHM?

• Damping refers to the gradual loss of amplitude in oscillations due to energy loss, often caused by friction or resistance.

• Damping increases the amplitude of oscillations, making them more pronounced.

• Damping has no effect on the oscillations in SHM.

• Damping is the process of increasing the frequency of oscillations.
