Define force in physics.
(b)
A resultant force $F$ acts on an object of mass $2.4\,\text{kg}$. Fig. 2.1 shows how $F$ varies with time $t$. The object starts from rest.
(b(i))[4]
On Fig. 2.2, display quantitatively how the acceleration $a$ of the object changes with $t$. Add suitable y-axis values.
(b(ii))[5]
On Fig. 2.3, display quantitatively how the momentum $p$ of the object varies with $t$. Add suitable y-axis values.
