The velocity does not change direction or magnitude. The object 1) may not be moving, or it 2) may be moving at a constant velocity. In the case of the latter, that means it's moving in the same direction and at a constant speed.

0it's velocity is constant and actual acceleration is equal to the friction. OR it's velocity is zero.

Zero acceleration means that the velocity doesn't change. It doesn't mean that there is no velocity.

if velocity is constant, that means then the net acceleration acting on the object is equal to zero

Yes, the velocity of a constantly (or not constantly) accelerated object will vary. Velocity is distance per unit time with a vector. It's speed (distance per unit of time) in a given direction. Under constant acceleration, the velocity is changing at a constant rate. But the velocity is changing. It is varying. The object could be speeding up or it could be slowing down. Or it could be changing direction. Any of these change velocity. An object that is experiencing constant acceleration will have its velocity varying. Why wouldn't it have?

Yes they can, an object moving with a velocity 100m/s could have the same acceleration as 1m/s. Both of them could be moving at constant speed, therefore they would have an acceleration of 0m/s^2. Definition of acceleration is 'the rate of change of velocity as a function of time'.

You can't. The net force simply means that the acceleration is zero. It could be at rest, or the object could be moving at a constant velocity.

I'm not a scientist, but the following seems reasonable to me. If your frame of reference is the earth's surface, then it seems clear that an object can have zero velocity and zero acceleration. You could even have non-zero velocity and zero acceleration. What seems impossible is to have zero velocity and non-zero acceleration. When you think of accelaration think of changing velocity. A car moving straight down the highway at a constant speed of 55 mph is neither speeding up nor slowing down. Though it has velocity, there is no change in its velocity so acceleration will be zero. For a car parked on the side of the road, on the other hand, its velocity will be zero but what about its acceleration? Is velocity changing? No, so it will have zero velocity and zero acceleration.Yes.

Yes, decreasing acceleration could still be positive, which yields an increase in velocity (speed). Velocity is the rate of change of position, and acceleration is the rate of change of velocity. As long as the acceleration is positive, then velocity is increasing. If acceleration becomes negative, then velocity is decreasing. ======================= I second that accelerated motion ! Even if the acceleration is petering out, as long as it's still more than zero, the speed can be increasing. By the way ... you can have a big solid acceleration, and it doesn't mean that the speed or the size of the velocity has to be increasing. Or even changing. But that's another story.

Acceleration is a change in velocity. Velocity is defined as the speed of an object in a specific direction. It is a vector quantity. Thus acceleration could be a rate of change of speed, velocity or both. In addition, acceration can be negative. In physics terms, there is no such thing as "Deceleration". Any change is considered to be acceleration.

Acceleration is the change in an objects velocity. Velocity is a very important term in physics, which is often confused with speed. The primary difference between the two is that velocity implies a specific direction (for example, 50m/s is speed of an object, whereas 50m/s North/Northeast is a velocity). Acceleration is negative when the speed of an object is increasing in the opposite direction. So, if an object is starting to move west, increasing by 5m/s each second, it's acceleration could be written 5m/s2 west or -5m/s2 east. Furthermore, as previously stated, Acceleration is the change in velocity. This is to say that a decrease in velocity would also be acceleration (the word "deceleration" does not exist in physics as it does in English). So, if the object is slowing down, it will have a negative acceleration in the direction it is moving.

Position is the place where an object is located. Speed is the rate at which position changes. Velocity is the speed and direction of motion. Acceleration is the rate at which velocity changes, and the direction of the change. So you could say that acceleration is the rate at which (the rate at which position changes and the direction) changes, and the direction of the change.

Yes. If it weren't so, an object that isn't moving could never be made to move at all! Of course, once you apply acceleration (which implies a change of velocity), the object's velocity won't stay zero. But for a brief instant, the velocity can be zero while accelerating.

From the information given, we don't really know. We know that the acceleration vector points to the right, but the velocity could be anywhere.

The definition of acceleration is: Any change of velocity, that is, speed or direction of motion. If an object is undergoing constant acceleration, then that could certainly include changes in the direction of its motion. One beautiful example is one object in a circular gravitational orbit around another one. The gravitational force directed toward the center of the circle, which is what keeps it in orbit, is a constant acceleration. And in any orbit, the direction of its velocity is constantly changing.

Stating that an object is in a state of equilibrium means that it has no forces currently acting on it. An object without forces acting upon it has no acceleration or deceleration. This means that if it was already moving, it would continue moving in the same direction and at the same speed (i.e. it would have constant velocity). If it was not moving, it would continue not moving (i.e. it would be stationary).

Acceleration is observed when velocity changes with respect to time. For instance, at t0 an object may be moving with a velocity of 2. At t1, it could be moving with velocity of 4, which means that it has doubled its velocity; thus accelerating. This can also be observed in reverse, where at t0 the velocity is 4 and at t1 the velocity is 2. The object then has decelerated, or has slowed down with respect to change in time.

No. Acceleration is defined as the rate of change of velocity. If velocity is constant, then its rate of change is zero. --------------------------------------------------------------------------- Another contributor obfuscated: If we were to get really picky with our vectors we could say that an object could have constant velocity in the x-y plane and still accelerate in the z-axis. Also a system of objects could have a net-velocity in 3-D space and still have a radial acceleration. A solar system traveling through space at constant velocity will have a radial acceleration, for each component part of the system, around the gravitational center of mass of the system.

dude324's answer: according tov=u+at if a=0 this implies v=u , thusyes it can. Even if acceleration is zero, it could have a constant velocity and could be moving.Lydia's answer: No, because an object at rest remains at rest unless acted upon by an unbalanced force.

Acceleration can be positive while velocity is negative for an object. For example, If the object (like a car) is moving in a negative direction (let's say west) and the brakes are applied to slow the car down. This causes the car to accelerate (commonly called deceleration) in the positive direction until it stops. Mathematically, one could work this out by taking the change in velocity over the change in time. acceleration = (V final - V initial) / time In this example, let's suppose V initial is -20 m/s and V final is -10 m/s, and the time for the velocity change is 5 seconds. Then acceleration would be : -10m/s - (- 20 m/s) divided by 5 seconds = 2m/s/s Thus, we see, an example of negative velocity yielding positive acceleration from an outside net force on the object via the brakes.

On the horizontal axis you would probably plot the time. On the vertical axis you could plot displacement, velocity or acceleration.

It could also be de-acceleration i.e slowing down.

Acceleration never depends on the instantaneous velocity.Acceleration is the rate at which velocity is changing, and the direction of the change.A car leaving a STOP sign at a neighborhood intersection, and the Space Shuttle in theprocess of a delicate orbital maneuver to link up with the International Space Station,could very well have the same acceleration.

If an object was in a circular orbit under the influence of some centralizing force, such as gravity, or magnetism, or electro-static, or even strong nuclear or weak nuclear - then it has a constant speed (not velocity, angular velocity) and a radial acceleration equal to v2/r.

You need more details.The final velocity could be 0However, you need to know the initial velocity, and the braking acceleration, and perhaps other acceleration/deceleration factors to know the true answer.

It could be a velocity graph or an acceleration graph. If the plot is a straight line it is constant velocity. If the plot is a curve it is acceleration.
