What are the necessary conditions in order for an object to acquire distance and displacement, thus acquiring motion?

There needs to be an origin.

The body must experience a force, for which it must have mass and an acceleration this force must be greater than any friction acting on body to avoid static friction.

The body can move towards any point outside the origin but if it returns and stops at origin, there is no displacement. It should not do that. If the body has  mass, it must be made of matter.

According to Newton's third law of motion, a force needs to be exerted on the body to move it.

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.

e

the answers would be
