The three equations are,
v = u + at.
v² = u² + 2as.
s = ut + ½at²
First equation:
The first equation of motion gives the relation between "velocity and time".
v = Final velocity
u = Initial velocity
a = Acceleration , due to gravity in earth , which is (-10m/s)
t = Time
Second equation:
The second equation of motion "gives the position-time relation".
v^2 = square of Final velocity
u^2 = square of initial velocity
2* a = 2 * acceleration
s = Displacement
Third equation:
The third equation of motion "gives the final velocity of an object under uniform acceleration given the distance traveled and an initial velocity".
s = Displacement
ut = Initial velocity * time
1/2at^2 = 1/2 * acceleration * time^2
i have done 4 questions.
Please go through the 5 questions asked below
Please, go through the questions
A car acquires a velocity of 72km/hr in 10 seconds starting from rest. find a) acceleration b)average velocity , c) the distance travelled in this time.
A body is accelerating at a constant rate of 10 m/s^2.if the body starts from rest,how much distance will it cover in 2sec?
An object undergoes an acceleration of 8m/s^2 starting from rest.find the distance travelled in 1 second.
A moving train is brought to rest within 20 seconds by applying brakes. find the initial velocity,if the retardation due to brakes is 2m/s^2.
A racing car has uniform acceleration of 4m/s^2.what distance will it cover in 10seconds after start?
change acceleration to 10 m/s. remove negative sign
What is the logic of if you add u and at we get v.
Can you explain it in all equations
What is the purpose of each equation in daily life. Can you explain with example
Like if you understood. 😀
also ask question, if you have any.
