In kinematics, what do we physically mean by equation Vx=V0x?
Answer :
Here, Vx is the x-component of the velocity of the given object after some time t.
And, V0x is the x-component of the Initial velocity of the object.
.
Therefore, Vx = V0x means that the x-component of the velocity remains constant. In other words there will be no acceleration of the object along x-axis.
This condition is used in Projectile motion, Where the horizontal component of the velocity remains constant - Because there is no horizontal acceleration (or Horizontal force) acting on the object.
