1. Displacement
--displacement can be defined as the shortest distance between the initial points and the final points....
2. Negative
--decelaration or retardation is negative accelaration....
3. Direction
--when an object is in uniform circular motion, its direction changes at every point and the magnitude of velocity increases....
4. Total Momentum
--This is a bit complicated, but, I'll try my best to explain it to you.....
Since the two colliding objects travel together in the same direction after the collision, the total momentum is simply the total mass of the objects multiplied by their velocity.
5. Third
--the third law says: "For every action, there is an equal and opposite reaction."....Yes, the working of a rocket depends upon this law. As the gases released by the rocket push the ground downwards, the rocket also goes upward......
....hope you understood.....

HINDUJINDABAAD:
please explain them I will mark your answer as brainlist
ok
thanks
hi. i have now explained the answer......check it now and pls mark it as brainiest and also, the third answer done by you is wrong....
kindly check it.....
third is velocity
no. the direction changes. how could if an object is moving in circular motion, the direction always changes but, the velocity may increase or decrease dear. but, still if you have any doubts, then consult your physics teacher.....in which shool do you study and from where are you? please tell if you don't mind.....
