Acceleration is the rate of change of velocity with time. Velocity is a vector physical quantity; both magnitude and direction are required to define it. The length of an imaginary straight path, typically distinct from the path actually traveled by P. Distance is a numerical description of how far apart objects are. In physics or everyday usage, distance may refer to a physical length, or an estimation Time in physics is defined by its measurement Formula Acceleration= change in velocity/time interval

Average velocity= displacement/time Oz (square root of) squared plus y squared. The gal, sometimes called Galileo, (symbol Gal) The SSL unit of speed and velocity is the ratio of two -? the mutterer second. The standard unit of displacement in the International System Of Units ( SSL ) is the meter (m). Meter (m) In the International System of Units (SSL), the unit of time is the second (symbol: Examples At an amusement park, when you ride a reallocates it starts slowly, then faster, then slows down again.

If you walk to a campsite 1 mile away and then jack to your start point within 1 hour: Your average speed would be: total distance/time = 2 miles/ 1 hour or 2 miles per hour How far does the earth travel in one year? In terms of distance, quite far (the circumference of the earth's orbit is nearly one trillion meters), but in terms of displacement, not far at all (zero, actually). At the end of a year's time, the earth is right back where it started from. It hasn't gone anywhere.
