Hey what is the formula to find accelration?

Answer 1

Acceleration is the change in speed divided by the change in time, so:
a = dv / dt.

Alternatively you could rearrange the other equations of motion, depending on what data you already have:

s = ut + 0.5at^2
v^2 = u^2 + 2as

Where: s = displacement in metres; u = starting velocity in m/s; v = final velocity in m/s; t = time taken in s; a = acceleration in m/s^2.

Answer 2

Change in velocity divided by time. If the acceleration is uniform, the change in velocity with time will be a straight line and the slope of the line will be the acceleration. If the acceleration is not uniform, the slope of the tangent to the curve at any given point of time will give the acceleration at that time. If x is the displacement (distance from a given point) of a particle and t is the time, we have:

velocity v = dx/dt and acceleration a = dx^2/dt^2

Acceleration is the double differential of displacement with respect to time, or the differential of velocity with resect to time.

Answer 3

There are a few of them:

Vf=Vi+A*(Df-Di)
Df=Di+Vi*(Tf-Ti)+0.5*A*(Tf-Ti)^2
Vf^2=Vi^2+2*A*D

Where,
Vf=final velocity of the object
Vi=initial velocity of the object
A=acceleration
Df=final distance of the object (most often the number placed in this one is the distance the object traveled)
Di=initial distance (usually 0 since most people choose to begin their calculation from this point to make things easier)
Tf=final time
Ti=initial time (this is also usually 0 since it makes the calculation easier)

also, F=MA is another good one

where,
F=force being applied to the object
M=the mass of the object

Also, if you know how to take integrals, acceleration is the integral of velocity. For example, if the equation for an object's velocity is y=2x, then the equation for its acceleration is y=x^2.

Answer 4

a=(v-u)/t
where v and u are the intial and final velocities respectively
and a=F/m
where F is the force applied on the body
and m is the mass of the body
also look through Newton's laws of motion for further reference.

Answer 5

the formula for accelaration is final velocity - initial velocity divided by time.
(v-u)/t
the S.I. unit of accelarltion is m/s2

Answer 6

Acceleration is rate of change in the velocity of an object.

The change can be in speed, direction or
BOTH speed AND direction.

Answer 7

Many formulas:
Main one is:
a=(Final Velocity-Initial Velocity)/time
other:
a=Force/Mass

Answer 10

change in velocity per unit time i.e. divide change in velocity by time interval.
