Question

what factors have to be kept in mind while describing motion​

Answer 1

Factors that have to be mentioned while describing motion of an object are as follows:

• The reference frame w.r.t which motion is taking place have to be kept in mind. For example ; according to a person on the ground a moving train is in motion , but according to a passenger on that same train , the moving train is stationary. Hence , pointing out the reference frame is very important.

• The direction of motion must be mentioned with respect to the 3D co-ordinate axes.

• The Velocity and acceleration of the object must also be described with both magnitude as well as directions with respect to the 3D co-ordinate axes.

Hope It Helps.

Answer 2

Important factors of motion are force,friction,inertia and momentum

Explanation:

• Force defines about push and pull of an object .

• Friction defines about the force acts in a opposite direction to the object motion.

• Inertia defines about the body is in a motion then it remain in motion with same speed until a force acts on it.

• Momentum defines about the  product of mass and velocity of an object.It is vector quantity.
