The figure above shows the same ideal spring in three different situations.
First without a mass hanging the spring is unstretched.
Next with the blue mass hanging the spring stretches.
Finally with the red mass hanging the spring stretches twice as much as it did with the blue mass.
How much does the red mass weigh compared to the blue mass? 

When the mass passes through B, it has

A block is attached to an ideal spring undergoes simple harmonic oscillations of amplitude A. Maximum speed of block is calculated at the end of the spring. If the block is replaced by one with twice the mass but the amplitude of its oscillations remains the same, then the maximum speed of the block will

The black graph pictured above represents the position-time graph for a spring-mass system oscillating with simple harmonic motion.
The colored, dashed graphs represent shapes of possible velocity time graphs for the same motion.
The vertical axis stands for position or velocity, but the scaling does not matter. The time axis is the same for all graphs.
Which colored graph best represents the possible velocity for the mass in this spring-mass system?

Simple harmonic oscillation of a given system can be specified completely by stating its: 

Simple harmonic motion (SHM) is a technical term used to describe a certain kind of idealized oscillation. A simple harmonic oscillation has

An object swinging on the end of a string forms a simple pendulum. Some students (and some texts) often cite the simple pendulum's motion as an example of SHM. That is not quite accurate because the motion is really

Simple harmonic motion (SHM) is a technical term used to describe a certain kind of idealized oscillation. Practically all the oscillations that one can see directly in the natural world are much more complicated than SHM. Why then do physicists make such a big deal out of studying SHM?

A spring-mass system oscillates back and forth in positive and negative directions. The graph above shows the acceleration of the mass.
Which of the following graphs best shows the velocity of the mass?
The time axes are scaled the same on all graphs

Consider a thingy hanging from a spring. The system is set vibrating by pulling the thingy down below its equilibrium position and then letting it go from rest.The frequency of the oscillation is determined by
