Question

can any body tell me physics motion formulas???...​

Answer 1

Answer:

Equations of motion relate the displacement of an object with its velocity, acceleration and time. The motion of an object can follow many different paths. Here we will focus on motion in a straight line (one dimension). We can therefore just use positive and negative magnitudes of the displacement, velocity and acceleration, where negative values are in the opposite direction to positive quantities.

If there is no acceleration, we have the familiar formula:

s, equals, v, t.

s=vt

where s,s is the displacement, v,v the (constant) speed and t,t the time over which the motion occurred. This is just a special case (a, equals, 0,a=0) of the more general equations for constant acceleration below.

For a constant acceleration a,a, an initial speed u,u and an initial position of zero:

Variable Equation

Velocity v, equals, u, plus, a, t,v=u+at

Displacement with positive acceleration s, equals, u, t, plus, one half, a, t, squared,s=ut+
