Yes. You could be moving left with an acceleration to the right (decelerating) and come to a stop before you begin to move to the right.
Yes, it is possible for the speed to be 0 while the acceleration is non-zero. This occurs when the object is momentarily at rest (speed is zero) while still experiencing acceleration due to a change in its velocity.
"Stationary" means zero speed. The object's speed is not changing, and the direction of the speed is obviously also not changing.By definition then, acceleration is zero.
Not with any sensible definition of "acceleration" and "velocity." You CAN accelerate an object and have it end up at zero velocity. But, if the acceleration remains a non-zero number, then the velocity can NOT remain at zero. Your question is like asking, "Can the value of a quantity change, but also remain the same?"
It's possible, but not necessary, that a particle moving with constant speedhas zero acceleration. In order for acceleration to be zero, it's also necessarythat the particle be moving in a straight line.An object moving with constant speed around a curve has acceleration."Acceleration" does not mean "speeding up".
Yes. Zero acceleration means you are not changing your speed (speed up or slow down) or changing direction. Zero acceleration is a constant speed in a linear direction. A speed implies you are moving.
Yes - for a while. Or indefinitely, if you will accept zero acceleration as "constant acceleration".
If your acceleration is zero, then yes, you are traveling at a constant speed. The path does not matter. Acceleration measures the change in velocity, so an acceleration of zero means that there is zero change in velocity and therefore the speed is constant.
On a child's swing. At each end of the arc of swing there is a moment when your instantaneous speed is zero, while your acceleration is not.
Yes. Acceleration is independent of speed. A perfect example of an object with zero speed but nonzero acceleration is an object at the apex of being thrown upward. The entire time it is in the air it is accelerating downward. At its maximum height its speed is zero.
This scenario is possible if the car is moving in a circular path at constant speed. In circular motion, even though the speed is constant, the direction of the velocity is constantly changing, which requires a centripetal acceleration towards the center of the circle. This acceleration is provided by a net force, known as the centripetal force, acting towards the center of the circular path.
Answer:Yes, but only instantaneously.Consider a thrown ball moving directly upward. At the highest point of its trajectory, the instanataneous velocity (the velocity at that precise instant) is zero even while the acceleration due to gravity remains non zero.
if acceleration is <0 and velocity =0 then you got the handbrake on
