What is the formula for calculating acceleration?
How do you calculate acceleration?
To calculate acceleration, divide the change in speed by the time during which the acceleration occurs. :)
How do you calculate distance from average acceleration?
From the average acceleration, take the average speed, by doing (V2 - V1)/2. Then, multiply that result by time to get the distance traveled. If all you are given is average acceleration and nothing else, there is insufficient data to make a calculation. The average acceleration of a rock in earth …gravity is about 9.78 m/s 2 at the equator. How far will it fall in two seconds? We don't know unless we assume it starts from a standstill or from some other arbitrary spot later on after it was dropped. But that was not specified. The distance the rock falls in a given period of time (which we weren't given) will be different from the distance it falls in the same period of time if the measurement is begun at a different time.

How can the acceleration of gravity on a pendulum be calculated?
Knowing mass and period of vibrations it's very easy to do using formula for pendulum.
How is acceleration calculated?
Acceleration = final velocity (v)- starting velocity (u) divided by time.
a=(v-u)/t.
example:.
a car starts from rest and accelerates to 50 m/s in 10 seconds..
u=0 m/s.
v=50m/s.
t=10s.
=> a=(v-u)/t => a=(50-0)/10.
a=5m/s².
Be careful with the units:.
Time should be expressed in seconds, …and all velocities in metres per second..
As a result, acceleration is expresses as metres per second per second, or metres per second squared..
Hope this helps! ( Full Answer )
What information do you need to calculate acceleration?
You need the speed and velocity +++ They are equivalent save that speed is a scalar and velocity a vector. You need intervals of time and distance.
What is the formula for acceleration?
a=dv/dt. By definition, acceleration is the rate of change of velocity. Inmathematical notation, it is given as the formula stated above. Two special cases: 1. When acceleration is constant: The rate of change is a constant. Therefore, it can be calculatedby: a=(vf - vi) / t where a is accelerat…ion vf is final velocity vi is initial velocity and t is time taken 2. When velocity is constant: Velocity is not changing. The rate of change of velocity is zero.Acceleration has to be zero. * * * * * Note that velocity and acceleration are both VECTORS. Therefore, anobject going round in a circle, at CONSTANT speed, has velocity andacceleration that are changing all the time - because the directionof motion is changing. ( Full Answer )
What is the formula for calculating displacement in which acceleration initial velocity and time are the variables?

State in words how acceleration is calculated?
There are two methods, it depends on what variables you have: 1. Subtract the initial velocity from the final velocity and divide that whole term by the time (Vf- Vi)/t = a 2. Square both the initial velocity and the final velocity and subtract the squared inital velocity from the squared final vel…ocity and that answer by two times the distance (Vf^2 - Vi^2)/2d = a ( Full Answer )

What is the formula used to calculate the acceleration of an object moving in a straight line?

Is acceleration a factor in calculating momentum?
No. Momentum is defined as mass times velocity, acceleration is the rate of change of velocity..
To be more accurate, velocity is a vector quantity, it has both magnitude and direction. Momentum is therefore also a vector quantity in the direction of the velocity with magnitude equal to the mass ti…mes the magnitude of the velocity:.
1) p = m v .
Acceleration is also a vector quantity and in the direction of the change in velocity direction and represents the rate of change of velocity:.
2) a = d v /dt.
Force is defined as the rate of change of momentum, and is therefore also a vector in the direction of the momentum change:.
3) F = d p /dt.
Substituting 1) in 3) we get:.
4) F = m(d v /dt).
And since 2) defines d v /dt as acceleration we get:.
5) F = m a .
In other words, force is mass times acceleration..
Note: The assumption above is that mass remains constant. This is an approximation that remains true only for slow speeds in comparison with the speed of light. These equations do not hold when approaching the speed of light as mass increases, and in fact makes it impossible to actually accelerate something to the speed of light. ( Full Answer )

How is velocity and acceleration calculated?
Velocity is the change in position per time. Average velocity can be calculated by dividing the change in position by the change in time. V avg = (x f - x i ) / (t f - t i ) where (x f - x i ) is the change in position, and (t f - t i ) is the change in time. Instantaneous velocity can be f…ound by calculating the slope (derivative) of the graph x versus t: V = (dx) / (dt) Acceleration is the change in velocity per time. Average acceleration can be calculated by dividing the change in velocity by the change in time. a avg = (v f - v i ) / (t f - t i ) where (v f - v i ) is the change in velocity, and (t f - t i ) is the change in time. Instantaneous acceleration can be found by calculating either the slope (derivative) of the graph v versus t: a= (dv) / (dt) or the 2nd derivative of the graph x versus t: a= (d 2 x) / (dt 2 ) ( Full Answer )
Is acceleration used to calculate momentum?
You may see acceleration mentioned in a momentum problem; but if it's there, it's only purpose is to help you find the object's velocity. All you need to know in order to find momentum is the object's mass and velocity.
What is the formula for calculating final velocity when you know the initial speed and the acceleration?
the formula for finding acceleration is final velocity, minus initial velocity, all over time. So if you have the acceleration and initial speed, which is equal to the initial velocity, you must also have time in order to find the final velocity. Once you have the time, you multiply it by the accele…ration. That product gives you the difference of the final velocity and initial velocity, so then you just add the initial velocity to the product to find the final velocity. ( Full Answer )

How do you calculate free fall acceleration?
The only thing you have to figure out is what planet the object is falling on. As long as you stay on the same planet, free-fall acceleration is always the same. It's called the acceleration of gravity on that planet. On earth, it's 9.8 meters (or 32.2 feet) per second per second. That means t…hat if an object is in free-fall near the earth's surface, its speed keeps growing, and at any time, it's always 9.8 meters per second (32.2 feet per second) faster than it was 1 second earlier. It doesn't even matter how heavy the falling object is ... everything falls with the same acceleration. That means that if you drop a small stone and a gigantic boulder out of an airplane at the same time ... or a feather and a bowling ball ... everything hits the ground at the same time. That's the way gravity works. Whenever you see something that doesn't work out that way, it's strictly a matter of the air that it had to fall through. ( Full Answer )
