Accelerating object can never have a zero velocity

The statement "Accelerating object can never have a zero velocity" is not entirely correct. An object can have a zero velocity at a certain moment and still be accelerating.

Here's a step-by-step explanation:

1. Velocity is a vector quantity, meaning it has both magnitude (speed) and direction. When we say an object has zero velocity, it means the object is momentarily at rest, but it doesn't mean the object cannot accelerate.

2. Acceleration is the rate of change of velocity. It is also a vector quantity. An object is said to be accelerating if it is changing its velocity. This change can be in the form of a change in speed or a change in direction or both.

3. Consider a simple case of a ball thrown upwards. When the ball reaches its highest point, its velocity is zero for a moment because it stops moving upwards and is about to start moving downwards. However, throughout this motion, the ball is under constant acceleration due to gravity.

4. So, even though the ball has a moment of zero velocity, it is still accelerating. This is because its velocity is changing - it's slowing down on the way up and speeding up on the way down.

5. Therefore, an object can have a zero velocity and still be accelerating. The key is that acceleration refers to a change in velocity, and velocity can change from a non-zero value to zero, or vice versa.
