What is uniform motion?
Motion where equal distances are covered in equal time intervals
What is non-uniform motion?
Motion where unequal distances are covered in equal time intervals
What is acceleration?
Rate of change of velocity — a = (v-u)/t — measured in m/s²
What is retardation?
Negative acceleration — when velocity decreases with time
Write the three equations of motion.
v=u+at; s=ut+½at²; v²=u²+2as
