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 velocity and that answer by two times the distance
(Vf^2 - Vi^2)/2d = a

What is the force of an object with a mass of 65 kg and an an unknown acceleration?
Force is calculated by Newton's second law, F=ma. So the Force is the acceleration of the object multiplied by the mass. In this case you need an acceleration to find the answer. If, say you wanted the force that gravity has on the object, it would be F=mass*acceleration due to gravity. Here, F=65kg*9.81m/s= 637 Newtons
What is the value of acceleration for a body?
Acceleration means how fast the body's velocity changes - in symbols, dv/dt. Average acceleration during a certain time is equal to (change in velocity) / (time elapsed). Since you are dividing a velocity by a time, the standard unit for acceleration is (meters / second) / second, but this is normally written as meters / second squared.
What is the formula for acceleration?
a=dv/dt. By definition, acceleration is the rate of change of velocity. In mathematical 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 calculated by: a=(vf - vi) / t where a is acceleration 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, an object going round in a circle, at CONSTANT speed, has velocity and acceleration that are changing all the time - because the direction of motion is changing.
What do Newton's three laws state?
1. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied. 2. The relationship between an object's mass (m), it's acceleration (a), and the applied force (F) is F=ma. Acceleration and force are vectors; in this law the direction of the force vector is the same as the direction of the acceleration vector. 3. For every action there is an equal and opposite reaction.
What happens if an unbalanced force applied to an object doubles?
The acceleration, from the Newton's law, can be calculated as:a0 = F0/mwhere F0 is the unbalanced force, m is the mass of the object.This is a linear equation, so if you double the force by 2, the acceleration will double as well:a1 = 2F0/m = 2(F0/m) = 2a0
In words how is acceleration calculated?
Acceleration is the rate of change of velocity. So if you were doing 10 metres per second, one second ago, and you are now doing 12 metres per second, your acceleration was 2 metres per second per second.
What is the acceleration?
Acceleration is the change in velocity with time, for linear (constant) acceleration it is calculated by: (End Speed -Start Speed)/time taken
This is calculated by change in velocity over time?
Acceleration.
How is accleration calculated?
By using the basic definition of acceleration, as (difference of velocity) divided by (time). In cases where the acceleration can be expected to change over time, to get the instantaneous acceleration, you need the limit of this expression, in other words, dv/dt.By using the basic definition of acceleration, as (difference of velocity) divided by (time).

How is force calculated if you know the mass and acceleration?
F = ma
What is the accelerate?
Acceleration is the change in velocity with time, for linear (constant) acceleration it is calculated by: (End Speed -Start Speed)/time taken
How is speed velocity and acceleration alike?
Acceleration is the derivative of velocity. In other words, acceleration is the rate at which the velocity is changing.
What is an accurate statement of an acceleration value translation from symbols into words?
Acceleration as in metres per second per second? The acceleration of a car for example? In words, acceleration is the rate of change of speed. (Speed is the rate of change of position).
What can be calculated by dividing the force exerted on the object by the mass of the object?
That's the object's acceleration.
Why does second sq occurs in the unit of acceleration?
That's because you are dividing a speed by a time. In the case of constant acceleration, acceleration can be calculated as (difference in velocity) / time. In fact, that's basically how acceleration is defined. The corresponding units are (meters / second) / second.
Why does gravity change velocity?
Gravity exerts a force on objects; such a force (if not counteracted by some other force) will cause an acceleration, according to Newton's Second Law. The amount of the acceleration can be calculated as a = F/m.
Is circuler motion an example of uniform acceleration?
No. Acceleration is towards the center of the movement, in other words, the acceleration vector changes all the time.
