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

An object’s acceleration is the rate its velocity (speed and direction) changes. Therefore, an object can accelerate even if its speed is constant – if its direction changes. If an object’s velocity is constant, however, its acceleration will be zero.

To have a constant velocity, an object must have a constant speed in a constant direction. Constant direction constrains the object to motion in a straight path thus, a constant velocity means motion in a straight line at a constant speed.

Velocity comes with direction, it indicates a speed at a direction. If velocity becomes negative, it is that speed in the opposite direction.

If velocity and acceleration have the same sign, you speed up. If velocity and acceleration have opposite signs, you slow down. Negative velocity = You move backwards. Negative acceleration = You slow down or you go faster in the backwards direction.

If velocity is 0 , that means the object is not moving, but with acceleration present, there is a force acting on the object.

An object having zero velocity implies that it is stationary at a particular location. If we plot it on a velocity-time graph which represents velocity on the y -axis and time on the x -axis, it is represented by x -axis. Value of y (velocity), is 0 for all values of x (time).

Velocity as a Vector Quantity Because the person always returns to the original position, the motion would never result in a change in position. Since velocity is defined as the rate at which the position changes, this motion results in zero velocity. As such, velocity is direction aware.

If acceleration is 0, the velocity is not changing. If the velocity is constant (0 acceleration) then the object will continue without slowing down or speeding up.

In the middle, when the object was changing position at a constant velocity, the acceleration was 0. This is because the object is no longer changing its velocity and is moving at a constant rate. Towards the end of the motion, the object slows down. This is depicted as a negative value on the acceleration graph.

Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.

Yes, you can have a zero velocity and a nonzero acceleration. Yes, you can have a zero velocity and a nonzero acceleration.
