Velocity displacement formula

Velocity displacement formula

S=Vo*t+at^2
S stands for distance
VO is the initial velocity
T is the running time
A is acceleration

In physics, the distance that an object passes in unit time is called speed. The formula for calculating speed is: speed = distance time, that is, v = st, and the unit is m / s. there are many physical quantities defined like this in junior high school, such as density, pressure, power, calorific value, etc. this method of defining physical quantities is called ratio definition method. We also have many physical quantities defined like this in senior high school physics, such as : the change of velocity of an object in unit time is called acceleration (Note: the change of velocity is expressed by △ V, which is equal to the difference between the two velocities; acceleration is expressed by letter A, international unit is m / S2)___ (2) if an object starts to move at a speed of 2m / s, and its speed changes to 8m / s after 5 s, then the speed change of the object in 5 s is △ v = 0___ M / S. (3) if the object in question (2) moves in a straight line with constant speed change (the change of velocity per unit time is equal), the acceleration of the object is obtained as a = m / s___ m/s2．

(1) According to the ratio definition method, the definition formula of acceleration is the ratio expression of velocity change and time, that is: a = △ VT; (2) the velocity change of object in 5S is △ v = 8m / s-2m / S = 6m / S; (3) according to the definition formula of acceleration, the acceleration of object is a = △ VT = 6m / s5s = 1.2m/s2; （3）1.2．
