Equation Of Motion
- This topic is nothing but there are some equation found out which are related with the motion.
- These motion are none other than the motions which we are doing in our daily life.
- We must see that how these great formulas are found by scientists because by just using of these formula we can find related things in motion.
- In this what i mean if you see a car or a man moving on a road and with help of some given information you can actually find the related things regarding this man or car, regarding things means speed, time etc.
- Now lets start the topic in detail;
- There are mainly two types of motion occure :-
A) Motion in a straight line with constant acceleration
B) Motion occur under the acceleration due to gravity
Now following are the equation of motion :-
Consider these notation regarding the equation
s = Distance (m)
u = Initial Velocity (m/s)
v = Final Velocity (m/s)
t = Time (sec)
a= Acceleration (m/s^2)
g= Acceleration due to gravity (m/s^2)
h= Height
A) Motion in a straight line with constant acceleration
1. s = u + at
2. s = ut +1/2at^2
3. v^2 = u^2 + 2as
B) Motion occur under the acceleration due to gravity
1. v = u + gt
2. h = ut +1/2gt^2
3. v^2 = u^2 + 2gh
- Value of g= 9.81 m/s^2
- Here as we all know force of attraction is always act in downward direction so we use g
- But if the body or force is act on the upward direction then at this time use '- g' instead of 'g'
