The image shows a pendulum in simple harmonic motion. the pendulum starts at a and swings to e.

which labels are correct? check all that apply.

e: net force is zero.
d: velocity is decreasing. acceleration is increasing.
a: velocity is zero.
c: acceleration is maximum.
b: velocity is decreasing. net force is decreasing.
e: velocity is maximum.
mark this and return save and exit next

D: Velocity is decreasing. Acceleration is increasing.

A: Velocity is zero.

The pendulum starts from rest at A, hence the velocity of pendulum at A is zero.

So velocity is zero at A

As the pendulum swings from A to E, it first gains speed from A to C and the speed decreases from C to E coming to a momentary stop at E.

Similarly, as the pendulum swings from A to E, the acceleration first decreases A to C (becoming zero at C) and the acceleration increases from C to E coming to a maximum at E.

So

D: Velocity is decreasing. Acceleration is increasing.

double the distance = divide strength by 4
