If you have an initial and final velocity and time you can figure it out with this equation, Vf squared=Vi squared1/2a(t squared) If you don't have those you cannot find acceleration.
However the acceleration on Earth is a constant -9.81
You can't. Acceleration is change in velocity. If given a constant velocity, the acceleration is zero.
You can't. You need either the final velocity or the acceleration of the object as well, and then you can substitute the known values into a kinematics equation to get the initial velocity.
If you know average speed then you cannot determine the acceleration: the very nature of being a average hides all the increases and decreases in speed which are the accelerations (technically, acceleration is change of speed in a direction). All average speed tells you is the constant speed at which you require to travel to cover the given distance in the given time; as the speed is constant, the acceleration is zero.
a = (v2 - u2)/2s where a is the acceleration between the initial point in time and the final point in time, u is the initial velocity v is the final velocity s is the distance travelled
You would need to use the equation f=ma In this equation, f means force, m means mass, and a means acceleration. So dividing the force by the mass will give you a figure for acceleration. If you know how long the object has been accelerating for, or how far, and what the initial velocity was (or whether it started off still) then you can work out the velocity from this acceleration.
You can't. Acceleration is change in velocity. If given a constant velocity, the acceleration is zero.
Velocity can only be identified by acceleration or time, even though we can also find it using force
Kinematics. Final velocity squared = initial velocity squared + 2(gravitational acceleration)(displacement)
If you are only given total distance and total time you cannot. If you are given distance as a function of time, then the first derivative of distance with respect to time, ds/dt, gives the velocity. Evaluate this function at t = 0 for initial velocity. The second derivative, d2s/dt2 gives the acceleration as a function of time.
You can't. You need either the final velocity or the acceleration of the object as well, and then you can substitute the known values into a kinematics equation to get the initial velocity.
Only one thing can be acceleration; the changing velocity of any given object. That's what acceleration is. Acceleration is caused by a net force on the object.
If you take initial velocity(Vi) to be zero and the final velocity (Vo) to be a known. Puting the knowns into a triganonomical equation and solving for the value of D would give an answer
Acceleration is a change in velocity over time - (change in velocity) / (time difference). So, you basically need two velocity measurements (or two assumed velocities), and the time difference between the measurements.
Only the acceleration brings a change in velocity.
There is only acceleration if the car's velocity changes. If it moves at a constant velocity, then there is no acceleration.
Acceleration = Change in velocity divided by the change in time. This formula only works if velocity is constant. If velocity is not constant, find the acceleration for both points in time. Then add the two accelerations and divide by 2.
You can only know the distance for sure if acceleration or deceleration is constant. Add the start and end velocities and divide by two and then multiply by the time to get your distance.
