AP 1 SHM

Front

What is the restoring force when the mass reaches point x = 0 in Simple Harmonic Motion (SHM)?

Back

Zero.

Front

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

Back

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

Front

If a simple pendulum's period is 4 s and its length is 1 m, what is the surface gravity on the hypothetical planet?

Back

2.5 m/s².

Front

What happens to the period of a pendulum if its length is increased by a factor of 4?

Back

The new period becomes 2t.

Front

At which point does a pendulum have the most kinetic energy?

Back

At the lowest point (O).

Front

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

Back

The elastic potential energy is maximum at the amplitude (A) and zero at the equilibrium position.

Front

What is the formula for elastic potential energy in a spring?

Back

U = 1/2 k x², where U is the potential energy, k is the spring constant, and x is the displacement from the equilibrium position.

Front

What is the definition of Simple Harmonic Motion (SHM)?

Back

SHM is a type of periodic motion where the restoring force is directly proportional to the displacement and acts in the opposite direction.

Front

How does mass affect the period of a simple pendulum?

Back

The mass does not affect the period; it only depends on the length of the pendulum and the acceleration due to gravity.

Front

What is the maximum speed of a mass in SHM?

Back

The maximum speed occurs as it passes through the equilibrium position and is given by v_max = Aω, where A is the amplitude and ω is the angular frequency.
