That's the formula for average acceleration.
vf or rather vf stands for final velocity
vi or rather vi stands for initial velocity
t stands for time.

A equals vf-vi divided by t?
(vf-vi)/ t is ?
What is the equation for average acceleration?
A equals Vf minus Vi divided by time equals triangle v divided by time
What is final speed divided by acceleration?
Final Velocity minus Initial Velocity (all together this is the change in velocity) divided by the average acceleration will give you the time it took for the object to reach that speed.(Vf - Vi) / Aaverage = Time
How is acceleration related to the distance and time elapsed?
acceleration cannot be calculated from these values alone unless one makes a few assumptions: Vf=final velocity Vi=initial velocity a=acceleration d=displacement t=time assume Vi=0 (Vf-Vi)/t=a Vf=at+Vi Vf**2=Vi**2+2ad (at)**2=2ad aatt=2ad att=2d a=2d/t**2
What is an equation in physics?
f=ma vf=vi+at s=vi+1/2at
A equals vf-vi divided by t?
(vf-vi)/ t is ?
What is the equation for average acceleration?
A equals Vf minus Vi divided by time equals triangle v divided by time
What is the formula used to calculate the accelerating?
A=Vf-Vi/t Acceleration is the final velocity minus the initial velocity divided by the time it too to reach it
What is final speed divided by acceleration?
Final Velocity minus Initial Velocity (all together this is the change in velocity) divided by the average acceleration will give you the time it took for the object to reach that speed.(Vf - Vi) / Aaverage = Time
What is the relationship between work and motion?
1) Work input = Force * distance 2) Force = mass*acceleration 3) Acceleration = (Vf - Vi) ÷ time 4) Force = mass * [(Vf - Vi) ÷ time] 5) Distance = Average velocity * time 6) Average velocity = (Vf + Vi) ÷ 2 7) Distance = [(Vf + Vi) ÷ 2] * time Eq#4 * EQ #7 8) Work input = mass * [(Vf - Vi) ÷ time] * [(Vf + Vi) ÷ 2] * time Time cancels 9) Work input = mass * (Vf - Vi) * (Vf + Vi) ÷ 2 10)(Vf - Vi) * (Vf + Vi) = Vf^2 - Vi^2 11)Work input = mass * [Vf^2 - Vi^2] ÷ 2 12)Work input = mass *( Vf^2 ÷ 2) - mass * (Vi^2 ÷ 2) 13)Kinetic energy = ½ mass *velocity ^2 14) Change in KE = (½ mass * Vf ^2) - (½ mass * Vi ^2) Equation #12 = Equation #14 so 15)Work input = Change in KE 16)Work input = ∆ KE
What is vi equals vf-at?
Yes recalling the first equation of motion ie Vf = Vi + at Here Vf is final velocity and Vi is the initial velocity. a the acceleration and t is the time Now taking at on the other side ie left side we get Vf - at = Vi This is what mentioned here.
How do you find the initial velocity just with the accelaration final velocity and time?
To find acceleration, you take Vi [Initial Velocity] and you subtract if from Vf [Final Velocity.] (Vi - Vf) If they Vi and Vf are already given, you take the two givens and you subtract them from each other. Vi minus Vf. Do not do Vf minus Vi or it will be wrong. After you do that, you divide your answer from T [Time] (Vi - Vf) a= _____ t Once you get your answer, that will be your acceleration.
If the average speed of a car is 80mph and it started from rest what is its final speed?
Vavg = (Vi + Vf)/2 Vi = 0 Vavg = Vf/2 Vf = 2*Vavg Vavg = 80 Vf = 160
What are the three cases of free fall?
Case 1 is Dropping (Simplest Case) Equations: vf=gt vf²=2gd d=gt²/2 t=square root of 2d/g case 2 is Throwing Down (general Case) Equations: vf =vi + gt vf² = vi² + 2gd d= vit + gt²/2 t= vf - vi /g d = vf² - vi²/2g Case 3 is Throwing up equations in Case 1 and 2 are usable it depends in the given ------------------------------------------------------------------------------- g= gravity vf= final velocity vi = initial velocity d= distance t= time there ^^

What is an equation in physics?
f=ma vf=vi+at s=vi+1/2at
How is acceleration measuered?
You can measure acceleration by using this formula below. vf= final velocity vi= initial velocity t=time a=accelration vf-vi/time
