Respuesta :
Any acceleration is referred to as having a non-zero acceleration. Positive acceleration or negative acceleration (also known as deceleration).
When an object changes direction while speeding up, slowing down, or remaining at the same speed, it experiences an acceleration that is not zero.
Which zero speed may simultaneously have non-zero acceleration?
At any given moment, a particle moving in one dimension at zero speed may also have acceleration that is greater than zero.
Any acceleration is referred to as having a non-zero acceleration. Positive acceleration or negative acceleration (also known as deceleration).
When an object changes direction while speeding up, slowing down, or remaining at the same speed, it experiences an acceleration that is not zero. Since velocity is the change in an object's position over time and a change in velocity indicates acceleration, any of these three scenarios would cause an object's velocity to change.
On the other hand, when an object stays still or moves in a straight line at the same speed, it has no acceleration. There is no acceleration because the object's velocity remains constant in both of these scenarios.
