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
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.
