Explanation:
1.Displacement can be zero because it is the shortest path and if we came at that place from where we start then the displacement is zero
Distance cannot be zero because it is the actual path travel by the body and it cannot be zero.
2. Uniform motion is the motion when the body travels equal distance in equal iterval of time.
3. One oscillation is completed by a pendulum when it starts from the extreme position A and moves to the other extreme position B and then returns to A. The time to complete one oscillation is called the time period. The time period of oscillation remains constant.
4.All oscillatory motions are periodic because each oscillations gets completed in a definite interval of time. ... Eg: Revolution of planets around the Sun is a periodic motion but not an oscillatory motion
5.The greater the force is, the greater the change in motion will be. 2—SURFACE on which the object is moved or the nature of the surface. i.e., rough surface, smooth surface, liquids etc. 3—WEIGHT The weight of the object or the amount of force on the surface by the object
6.This question has something cut.
I can tell you the hint.
Average speed =Total distance/total time
speed=Distance /time
v=u+at
s=it+1/2at^2
v^2=u^2+2as
