vav = average velocity in m/s. t = change in time in s (second) a = acceleration in m/s2. v = instantaneous velocity in m/s. Constant velocity. vav = d/t Accelerated motion. a = (vt – vo)/t Kinematic formulas. d = vot + ½at2. d = ½(vo + vt)t. vt = vot + at. vt2 = vo2 + 2ad. Graphing constant velocity in one dimension d v a

Acceleration = (final velocity – initial velocity) / time difference. The velocity at 30cm from the end (your fastest, hopefully) will be our final velocity for every calculation. To find the acceleration between 40cm and 30 cm, just subtract your 40cm velocity from the 30cm velocity and divide by the time difference.

Velocity v Speed in a particular direction. A ratio of displacement to travel time elapsed. Meters per second (m/s) 1m/s ≈ 2.24 mph . 4.5m/s = 6min/mile pace Average Velocity (symbol = ): when we measure velocity, average velocity is what we will actually measure. This is the average speed of an object as it travels through a given distance.
