The period of a pendulum is dependent on
weight of bob
length of pendulum
gravity
starting position of bob
Which length of the pendulum given below will oscillate the fastest
0.75 m
75 cm
120 cm
2 m
The gravitational acceleration of Earth is 9.81 ms−2 and that of the Moon is 1.62 ms−2 . which of the following statements are correct
The pendulum oscillates faster on the Moon.
The pendulum oscillates slower on the Moon.
The pendulum has the same oscillation rate Earth as on the Moon.
The pendulum does not oscillate on the Moon
Which of the following correctly describes the movement 1 period of the pendulum
B to A to B to C
A to C and back to A
B to C to B to A to B
A to C
If T is the period of the pendulum, l its length and g is the gravitational acceleration, which of the following correctly describes the equation for a period of a pendulum
T = πgl
T = πlg
T = 2πlg
T = 2πgl
If I want to increase the period of the pendulum I would
Make the bob of the pendulum lighter
Make the length of the pendulum longer
Start the motion of the pendulum by displacing the bob of the pendulum further from its center
None of the above
Mutu, Ali and Chan each did 3 measurements to determine the period of a pendulum. They measured ten periods of the pendulum oscillations to do so. The values they reported in seconds were as follows:
Mutu - 1.67, 1.72, 1.66
Fara - 1.77, 1.91,1.59
Chan - 1.75, 1.90,1.96
Tim - 1.69,1.85,1.77
Whose measurements are the most consistent?
Mutu
Fara
Chan
Tim
Why does a pendulum that is in motion eventually stops?
It loses energy due to frictional forces
The starting displacement of the oscillation was too small
It encounters air resistance
All of the above
