This video explains how the direction and gradient of a line on a velocity-time graph can tell us whether an object is accelerating, moving at a constant velocity or decelerating. Velocity time graphs ...
A horizontal line means the object is moving at a constant speed. The gradient of the line = the rate of change of speed. The steeper the line, the greater the increase in speed. The area under the ...
In astronomy, we rely heavily on visual information. Images from telescopes, graphs of light curves, plotted orbits, spectra ...
