No. A velocity indicates a speed and direction. An acceleration is a change in speed or direction.
When a body has constant velocity, the acceleration is zero. This is because acceleration is the rate at which velocity changes, so if velocity is constant, there is no change and hence no acceleration.
Yes, it is possible. When a body thrown upward (from the surface of Earth or any other planet but with velocity small enough not to overcome the gravity) and reaches its maximum elevation its velocity is zero but the acceleration is g (due to gravity).
The body is not zero, but the sum of all forces on it is. -- "Uniform velocity" means no acceleration. -- Acceleration is force/mass . -- If acceleration is zero, that's an indication that force must be zero.
When acceleration is zero, the object's velocity can still be changing if the initial velocity is not zero. However, if acceleration is zero and the initial velocity is also zero, then the object's velocity will remain constant.
Acceleration is the CHANGE in velocity; you're assuming CONSTANT velocity. So the acceleration is zero.
If a body is moving with a uniform velocity, its acceleration will be zero. Acceleration is the rate of change of velocity, so if the velocity is constant, there is no change in velocity over time and thus zero acceleration.
Yes, it is possible for a body to have zero velocity but still have acceleration. This occurs when the body is changing its direction of motion, even though its speed remains constant. The acceleration in this case is due to the change in direction, not speed.
The acceleration of a body with uniform velocity is zero because acceleration is the rate of change of velocity. If the velocity is constant, then there is no change in velocity over time, so the acceleration is zero.
Yes, a body can have zero velocity and still have acceleration. For example, when a car is at a complete stop but then accelerates to start moving, it has zero velocity at the moment before acceleration kicks in. Another example is when an object reaches the peak of its motion and momentarily stops before accelerating back downwards due to gravity.
Yes, but only for an instant. For example, if you throw a stone up, when it is at its highest point it has a velocity of zero, but its acceleration is -9.8 m/s2. If there is acceleration, the velocity can not remain at zero.
No, a body cannot have acceleration when it is momentarily at rest. Acceleration is the rate of change of velocity over time, so if the body is at rest, its velocity is zero, and therefore its acceleration is zero as well.
Yes, a body can have zero velocity and still be accelerating if its speed is changing, either increasing or decreasing, over time. This is because acceleration is a measure of how the velocity of an object is changing, regardless of its current velocity.
