Can you have a northward velocity and an southward acceleration?

Yes it can. If an object moving northward suddenly starts to decelerate its acceleration is southward. The velocity of the object in the picture is northward, its acceleration is downward.

Is it possible to have a northward velocity with Westward acceleration?

A westward acceleration while moving northward? Yes, an object can be moving at the same time that it is also slowing down. During this period, its acceleration is in the opposite direction of its velocity.

Is it possible to have a positive velocity and negative acceleration?

An object which moves in the positive direction has a positive velocity. If the object is slowing down then its acceleration vector is directed in the opposite direction as its motion (in this case, a negative acceleration).

Can an object have an increasing velocity and a constant acceleration?

A object undergoing a constant acceleration has a constantly changing velocity. If the acceleration always points in the same direction as the velocity, the trajectory will be no different than if there were no acceleration, but in general acceleration will change the trajectory. Yes it can.

Is it possible that a period has a southward velocity but northward acceleration If yes give an example?

Yes, when brakes are applied to a moving cycle, the directions of velocity and acceleration becomes opposite.

Can an object have zero velocity but nonzero acceleration?

It is possible to have a non-zero value of acceleration when the velocity of a body is zero. At the highest point, the velocity of the ball becomes zero, after which it starts to fall down. At this point, the velocity of the ball is zero yet its acceleration is equal to g=9.8m/s2.

Can we have eastward velocity but westward acceleration?

Yes a body can have eastward velocity and westward acceleration e.g. SHM.

Can a body have eastward velocity but westward acceleration?

Yes, it possible, in this case – ve acceleration known as retardation. Answer: An object can have an Eastward velocity while experiencing a Westward acceleration. When you have taken your right foot off the accelerator, the car will not accelerate eastward anymore but still it will have a velocity.

Can an object have negative velocity and negative acceleration?

They are very precise. There are no such terms as NEGATIVE velocity and NEGATIVE acceleration. If you define velocity as SPEED with a vector, then as speed can only be zero and never negative, so how can velocity be negative? Direction is NEUTRAL with regard to negative or positive.

What does it mean if an object has a positive velocity but a negative acceleration?

Another way to say this is that if the acceleration has the same sign as the velocity, the object will be speeding up. And if the acceleration has the opposite sign as the velocity, the object will be slowing down.

Can an object have constant acceleration but not constant velocity?

An object with a constant acceleration should not be confused with an object with a constant velocity. Don’t be fooled! If an object is changing its velocity -whether by a constant amount or a varying amount – then it is an accelerating object. And an object with a constant velocity is not accelerating.
