Question

a particles is moving with a constant speed on Horizontal smooth surface along a straight line . a force is not required to

a. change the direction
b. increase its speed
c. decrease its speed
d. keep it moving with uniform velocity​

Answer 1

Answer:

Ans: d) if we assume that the surface has zero friction then no force is required to keep the object moving with uniform velocity
