Answer:
Acceleration
Explanation:
Acceleration is the rate of change in velocity. Mathematically, it is given by :
[tex]a=\dfrac{v-u}{t}[/tex]
Where
v = final velocity of an object
u = initial velocity of an object
t = time taken
It can also be written in differentiating form as :
[tex]a=\dfrac{dv}{dt}=\dfrac{\Delta v}{\Delta t}[/tex]
For an freely falling object, the value of acceleration is equal to g i.e. 9.8 m/s².
