Draw the diagram of uniform motion of V-t graph and d-t graph.

Non-uniform motion of V-t graph and d-t graph.

Answer 1

Answer:

1.) SI unit of speed is metre per second (m/s)

4.) SI unit of average speed is Total distance covered by total time taken (d/t)

Answer 2

Answer:

speed= distance ÷ time

s.i. unit = m/s
