Motion of a Pendulum & Spring

Front

What is the restoring force in a pendulum?

Back

The restoring force in a pendulum is the force that acts to bring the pendulum back to its equilibrium position, which is directed towards the center of the swing.

Front

At which position is the restoring force equal to zero in a pendulum?

Back

The restoring force is zero at the highest points of the swing, where the pendulum momentarily comes to rest before changing direction.

Front

What is the relationship between acceleration and position in simple harmonic motion?

Back

In simple harmonic motion, acceleration is maximum at the extremes of the motion and zero at the equilibrium position.

Front

What is the condition for a pendulum to exhibit simple harmonic motion?

Back

A pendulum exhibits simple harmonic motion when the angle of displacement is small (typically less than 15 degrees).

Front

What component of weight contributes to the restoring force in a pendulum?

Back

The restoring force comes from the X component (or tangential component) of the weight.

Front

What happens to the acceleration of a pendulum at its lowest point?

Back

At the lowest point, the acceleration is zero because the pendulum is momentarily at rest before changing direction.

Front

How does the mass of a pendulum affect its period?

Back

The mass of a pendulum does not affect its period; the period is determined by the length of the pendulum and the acceleration due to gravity.

Front

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

Back

The formula for the period (T) of a simple pendulum is T = 2π√(L/g), where L is the length of the pendulum and g is the acceleration due to gravity.

Front

What is the significance of the equilibrium position in a spring system?

Back

The equilibrium position is where the net force acting on the spring is zero, and it is the position where the spring is neither compressed nor stretched.

Front

What is the relationship between force and displacement in Hooke's Law?

Back

Hooke's Law states that the force exerted by a spring is directly proportional to the displacement from its equilibrium position, expressed as F = -kx.
