VELOCITY AND ACCELERATION

Seite 1

ß For the last equation to apply, a must have constant magnitude and direction.

v/t graph: gradient = acceleration, area = distance travelled

a/t graph: area = velocity

Velocity: The rate of change of displacement per unit time

Acceleration: The rate of change of velocity per unit time

All objects at any particular point on the Earth’s surface have the same value of free fall acceleration because the magnitude of the gravitational and inertial mass of each object is the same.
