... A mass on a spring oscillates back & forth with simple harmonic motion of amplitude A. A plot of displacement (x) versus time (t) is shown below. At what points during its oscillation is the speed of the block biggest? 1. When x = +A or -A (i.e. maximum displacement) 2. When x = 0 (i.e. zero displac ...

... f. The period for the oscillating system will be the same as it was on Earth. According to the formula for period of a mass-spring system, the only two factors that determine the period are the mass m and the spring constant k, and those two values are the same on Mars as they were on Earth. g. The ...

Gravity is a force exerted by masses.
... The minimum speed needed to send an object into orbit is approximately 8000 meters per second. At this speed, the path of a falling object matches the curve of Earth’s surface. If you launch a spacecraft or a satellite at a slower speed, it will eventually fall to the ground. A spacecraft launched a ...
