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.
Acceleration is 0.25m/s2 (A = force/mass).
Force= Mass x Acceleration
Force equals mass times acceleration, so an alternative formula is acceleration equals force divided by mass. Therefore if the mass is decreased, the acceleration goes up. Thus a 100 HP engine on a motor cycle produces more acceleration than the same engine on a car.
Force = Mass x Acceleration Note that the "Force" here refers to the resultant force if there is more than one force acting on the object.
Newton's 2nd Law is Force equals Mass times Acceleration, or F=ma.
The formula to calculate acceleration is: acceleration = (final velocity - initial velocity) / time.
The formula for calculating the magnitude of acceleration is acceleration change in velocity / time taken.
The formula for force is F = ma, where F represents force, m is mass, and a is acceleration. For acceleration, the formula is a = F/m, where a is acceleration, F is force, and m is mass.
The formula for positive acceleration is: acceleration = change in velocity / time taken. Positive acceleration means an increase in velocity over time.
The formula for calculating acceleration is: acceleration change in velocity / time.
My bad, im asking why the formula isnt acceleration= force - mass
The formula for force is F = m * a, where F is the force, m is the mass, and a is the acceleration. The formula for mass is m = F / a, and the formula for acceleration is a = F / m.
The formula for acceleration can be rewritten as a = Δv / Δt, where acceleration (a) is equal to the change in velocity (Δv) divided by the change in time (Δt).
The formula for centripetal acceleration is a v2 / r, where a is the centripetal acceleration, v is the velocity, and r is the radius.
The formula to calculate the net acceleration of an object is: Net Acceleration (Final Velocity - Initial Velocity) / Time.
The Atwood machine acceleration formula is a (m2 - m1) g / (m1 m2), where a is the acceleration of the system, m1 and m2 are the masses of the two objects, and g is the acceleration due to gravity. This formula is used to calculate the acceleration of the system by plugging in the values of the masses and the acceleration due to gravity.
The formula for the magnitude of acceleration in physics is a v / t, where a represents acceleration, v is the change in velocity, and t is the change in time.
