Hi everyone. So since the direction of the acceleration is the same as the direction of the "PUSH",
may I know what would happen to the velocity of an object if it was
(a.) Accelerating to the right (+i), initially at rest
(b.)accelerating right (+i), initially moving to the right (+i)
(c.) Accelerating right (+i), initially moving to the left (-i)
My predictions :
(a.) Velocity increases by a constant velocity (considering there is no friction) in the positive direction as the object moves away from the Reference point.
(b.) Velocity will continue to change by a constant value in the positive direction form the Reference point.
(c.) I'm confused about this one. Since "PUSH" = Direction of acceleration , I predict that the object will initially movie in a negative direction and have a negative velocity and negative acceleration and then when the object is pushed in the right direction, the velocity increases and so does acceleration. I think I'm not correct with this description
Your help would be most appreciated! :)

(a) Yes, velocity to the right increases by a constant amount per unit time, but also even if there was friction because there must be a net accelerating force to the right which overcomes any friction force.
(b) Yes
(c) There is no negative acceleration here, it is always positive and constant.
So the object initially slows down by a constant amount per unit time until it momentarily stops, then it starts to move to the right and its velocity keeps increasing by the same constant amount per unit time.
