motion in a straight line

Dear student,

Instantaneous velocity mean change of displacement in extremely small amount time. (in math way, taking[ lim t--->0 (change in displacements/change in time) ].

Instantaneous speed is the same but change displacement  to distance. So,because of very very small change in time, magnitude of distance and displacement will be same for any direction the object is moving.

1. Explain path length and displacement with illustrations and distinguish them. 2. Define uniform velocity of an object moving along a straight line. What will be the shapes of position-time and velocity-time graphs of such a motion? Find the distance travelled by the uniformly accelerated object in one dimension in nth second. Draw velocity-time graph of a uniformly accelerated motion in one dimension and explain that the distance travelled is equal to the area under velocity-time graph. ted motion deduce the equations of motion in (i) From the velocity-time graph of uniform accelerated motion. velocity and time (ii) distance and time (iii) distance and velocity.
