A mass on a spring in SHM has amplitude A and period T. What is the total distance traveled by the mass after a time interval T?
4A
A mass on a spring in SHM has amplitude A and period T. What is the net displacement of the mass after a time interval T?
0
A mass on a spring in SHM has amplitude A and period T. How long does it take for the mass to travel a total distance of 6A?
1.5 T
A spring can be stretched a distance of 60 cm with an applied force of 1 N. If an identical spring is connected in parallel with the first spring, and both are pulled together, how much force will be required to stretch this parallel combination a distance of 60 cm?
2 N
A mass oscillates in simple harmonic motion with amplitude A. If the mass is doubled, but the amplitude is not changed, what will happen to the total energy of the system?
The total energy will not change
If the amplitude of a simple harmonic oscillator is doubled, which of the following quantities will change the most?
Total mechanical energy
A glider with a spring attached to each end oscillates with a certain period. If the mass of the glider is doubled, what will happen to the period?
The period will increase
A glider with a spring attached to each end oscillates with a certain period. If identical springs are added in parallel to the original glider, what will happen to the period?
The period will decrease
A mass oscillates on a vertical spring with period T. If the whole setup is taken to the Moon, how does the period change?
The period will not change
Two pendula have the same length, but different masses attached to the string. How do their periods compare?
Period is the same for both cases
Two pendula have different lengths: one has length L and the other has length 4L. How do their periods compare?
The period of 4L is two times that of L
Period of a spring
T = 2pi(m/k)1/2
Period of a pendulum
T = 2pi(l/g)1/2
Spring constant
k = (mg)/x OR Fg/x ; x is the distance moved from free length
