Question

Define displacement and velocity in twee dimensions.​

Answer 1

Therefore the motion of an object at constant velocity is represented by a straight line: x=x0+vt x = x 0 + vt , where x0 is the displacement when t=0 (or at the y-axis intercept). ... The velocity can be positive or negative, and is indicated by the sign of our slope. This tells us in which direction the object moves.

Answer 2

Explanation:

time (x vs. t ) shows the same change in position over each interval of time. Therefore the motion of an object at constant velocity is represented by a straight line: x=x0+vt x = x 0 + vt , where x0 is the displacement when t=0 (or at the y-axis intercept). ... This tells us in which direction the object moves.
