Question

What factors have to be kept in mind while describe motion

Answer 1

FACTORS EFFECTING MOTION OF AN OBJECT ARE

1—FORCE A force can slow down or speed up an object. A force can change the direction in which an object is moving. 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.

These three factors have to be kept in mind while describing motion

Answer 2

Here is your answer

Fluid Friction - friction resisting the movement through a fluid or a gas.

Sliding Friction - friction resisting the movement of two objects sliding in opposite directions or across one another.

Rolling Friction - friction resisting the movement of a wheel or other round object moving along a surface.
