The general formula for calculating speed or velocity is given by :-
v = s / t
[ s divided by t]
where v : velocity
s : displacement/distance
t : time
s (displacement) is actually change in the distance, but it can be generalized as just distance traveled.
units include : meter, kilometer, miles and other sub types(centimeter, inch)
t is the time taken for the object to move the above mentioned distance.
units : seconds, hours and other related measures of time.
eg : if an object was moved by 15 meters in 3 seconds, its velocity v is given by:
v = 15/3
= 5 meters/second or m/s
distance/velocity = time
The kinetic energy of an object depends on its mass and velocity. The relevant formula is: K.E = 0.5mv2 , where m = mass and v = velocity.
formula for computing square of number n is n*n or n2
Acceleration can be found by computing the slope of a velocity vs. time graph. Acceleration is the rate of change of velocity over time, so the slope of a velocity vs. time graph represents this change in velocity.
In general the velocity (speed) of an object undergoing constant acceleration, a, is V=vo+at where vo= initial velocity and t= duration of acceleration. For an object in free fall in a vacuum, a=g=9.8m/s2.
velocity is a vector quantity. Its magnitude is given by (velocity)= (distance)/(time)
The formula for velocity is (v = d/t) or (velocity = distance/time).
The final velocity of an object can be calculated using the momentum formula, which is: momentum mass x velocity. To find the final velocity, rearrange the formula to solve for velocity: velocity momentum / mass.
Velocity is distance / time
The formula for computing elasticity of demand is: (Q1 - Q2) / (Q1 + Q2) ------------------------------ (P1 - P2) / (P1 + P2)
The formula for calculating velocity in a pipe is velocity flow rate / cross-sectional area.
a = Δv/Δt also: a = Δv/t Δ = Stands for Delta v = Stands for Velocity t = Stands for Time a = Stands for Acceleration / = Stands for Division (Divide)
