Question

14. The displacement of a moving object in a given interval of time is zero. Would the distance
travelled by the object also be zero? Justify you answer.
15. How will the equations of motion for an object moving with a uniform velocity change?
16. A car starts from rest and moves along the x-axis with constant acceleration 5 m/s for 8
seconds. If it then continues with constant velocity, what distance will the car cover in 12​

Answer 1

Answer:

14.no it is not possible.because the object is moving that means it must cover some distance.if it starts its journey from a point and comes back to the point then its displacement is 0 but distance will have some numerical value..

just let you are going to school and comes back your home.displacement =0 but distance will have a numerical value.

15.that means there is no acceleration. a=0

v=u (v=u+at)

v²=u² (v²=u²+at)

s=ut (s=ut+1/2 at²)
