What is the intermediate displacement formula in Physics

You are asking about the velocity formula for the midpoint of a period of displacement, v(middle) = under the root sign (v1 2 + v2 2) 2

Formula for linear motion at uniform variable speed.

1) Speed formula: vt=v0+at

2) Average velocity formula: v=(v0+vt) 2

3) Displacement formula: s=v0t + 1 2at 24) Velocity-displacement formula: vt 2 - v0 2=2as

vx 2 = square of the initial velocity under the root sign + 2 square of the final velocity

Under the root number (initial velocity squared plus final velocity squared 2).

Derivation of the velocity displacement formula.

Intermediate moment VP, intermediate displacement vs

vp=vo+at}

vt=vp+at}vp=vo+vt 2=average speed.

vs²—vo²=2as=x}

vt²—vs²=2as=x}vs²—vo²=vt²—vs²2vs²=vt²+vo²

vs=√[vt²+vo²]/2

The velocity of the intermediate position is the arithmetic mean, and the velocity of the intermediate moment is the square average, which is inequal by the mean.

It can be seen that the instantaneous velocity in the middle position.

should be greater than the instantaneous velocity in between.

Velocity derivation of intermediate displacements.

The initial velocity vo, the final velocity v, and the intermediate displacement velocity v.

2-vo 2=2ax in v

v 2-v in 2=2ax

v 2 - vo 2 = v 2 - v 2

v = (vo 2 + v 2) 2

Denote that the middle displacement velocity is equal to the root mean square.

Displacement formula: s=v0t+ at

Velocity-displacement formula: vt -v0 = 2as

If an object moves from its initial position to its end in a certain period of time.

The special position is from the initial position to the genus.

The directed segment at the end is called the displacement. Its magnitude is the straight-line distance from the initial position to the last position of the moving object; The direction is from the beginning position to the last position. The displacement is only related to the beginning and end position of the object's motion, not the trajectory of the motion.

If the particle returns to its original position after a period of time during motion, then the distance is not zero and the displacement is zero.

x=x2-x1 (last position minus initial position) Note that the displacement is a straight-line distance, not a distance.

In the International System of Units, the principal unit of displacement is: meters. In addition: centimeters, kilometers, etc.

2.Useful inferences.

s=v0t +1/2 at²

s=v average t

s=(v²-v0²)/(2a)

These seem to be the ones that are commonly used, where v0 is the initial velocity, v is the end velocity, t is the time, and a is the acceleration.

Any linear motion:

s=v average t

Uniform speed linear motion:

s=(v1+v2)t/2

s=v0t+at^2/2

s=(v^2-v0^2)/2a

That's not how physics is learned!
