Movement carried out by a mobile that increases its speed uniformly, this increase or variation of speed in each unit of time is known as acceleration.
The Equation of Uniformly Accelerated Motion MUA it is:
Data | Formula | App |
a = acceleration (m / s2) | d = vt + 1/2 at2 | distance |
v = initial velocity (m / s) | d = 1/2 at2 | vi= 0 |
t = time (s) | ||
d = distance (m) | a = vF - vi / t | acceleration |
vt= final velocity (m / s) | ||
v = velocity | v = vi + at | velocity |
MUA basics
Acceleration: It is the variation that the speed experiences in each unit of time.
Instant acceleration: It is the acceleration carried by a mobile at a given moment.
a = v / t
Average acceleration: It is the average increase or decrease that the speed experiences in each unit of time.
a = m / s2
vF= m / s
vi= m / s
t = s
Formula a = vF-vi / t
SAMPLE MUA:
Calculate the acceleration of a particle that starts with a velocity of 3.5 m / s and reaches 8 m / s in a time of 3 s.
a = vF-vi / t = 8m / s - 3.5 m / s / 3 s = 1.5 m / s2
