An object is moving, with uniform acceleration a

An object is moving, with uniform acceleration a. Its initial velocity is u and after time t its velocity is v. The equation of its motion is v = u + at. The velocity (along y-axis) time (along x-axis) graph shall be a straight line

  1. passing through origin
  2. with x-intercept u
  3. with y-intercept u
  4. with slope u

Answer

The equation of motion is: v = u + at or v = at + u

The general equation of a straight line graph is: y = mx + c

m is the gradient, which is a.

c is the y-intercept, which is u.

The correct option is C.
