Q1Physical Quantities and UnitsKinematicsFree sample

(a)

In the following list, underline all quantities that are SI base quantities.

charge electric current force time

(b)

Under certain conditions, the distance $s$ moved in a straight line by an object in time $t$ is given by

s = \frac{1}{2}at^2

where $a$ is the acceleration of the object.

State two conditions under which the above expression applies to the motion of the object.
