| + | - When the mass is at the top of its oscillation, the velocity is at a minimum and its acceleration is at a maximum (the force of gravity and the force of the compressed spring are pulling and pushing the mass down) | ||
| + | - When the mass is at the equilibrium point, its velocity is at a maximum, and its acceleration is at a minimum (the spring and the force of gravity counteract each other and the net force is 0) | ||
| + | - When the mass is at the bottom of its acceleration, the velocity is at a minimum and the acceleration is at a maximum value (although the force of gravity is still pulling the mass downwards, the force of the stretched spring pulling the mass upwards will result in a net force that causes the same magnitude acceleration as when the spring is at the top of its oscillation) | ||
| + | - Increasing the spring constant affects the stiffness of the spring. The higher the constant, the stiffer the spring is. A higher spring constant results in smaller amplitude for position, but higher amplitudes for velocity and acceleration. Additionally, the frequency of the oscillation increases, and therefore the period decreases | ||
