Answer:
The mathematical formula expressing Newton's Second Law of Motion is :
F = ma
Step-by-step explanation:
Second Law of Motion : It states that external unbalanced force is directly proportional to rate of change of momentum.
Its formula becomes : F = ma
![F = (m(v-u))/(t)](https://img.qammunity.org/2021/formulas/chemistry/middle-school/1fddb9s6c542fomw8iu2nbdq6mtpjq11vb.png)
Put,
![((v-u))/(t) = a](https://img.qammunity.org/2021/formulas/chemistry/middle-school/whmdl8kl5d8zvztcydicpklxeyawdtp4vl.png)
F = ma
