Throwing a ball straight up in the air. It will reach some peak where the velocity is zero, but the acceleration due to gravity is a constant -9.8m/s^2.
Yes. Zero velocity is a velocity; if it is always zero then it is a constant velocity.
Zero relative velocity to another object, sure no problem. Zero absolute velocity, not possible as there is no absolute reference to compare to.
As, in the velocity-time graph, curves passes through zero means 'when time is zero velocity is zero'. Velocity is time derivative of displacement. So displacement is maximum or minimum when time is zero in position-time graph.
If your velocity is constant, then your acceleration is zero.
To reduce the velocity
Yes. For example a swinging pendulum has zero velocity at the turning point but acceleration is not zero.
Yes. Zero velocity is a velocity; if it is always zero then it is a constant velocity.
Yes, if, for example, a car races around a circuit, its total displacement is zero and so its velocity, at the end of every lap, is zero.
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.
For example, an object thrown upwards, when it is at its highest point. This situation is only possible for an instant - if the acceleration is non-zero, the velocity changes, and can therefore not remain at zero.
No, The velocity CHANGE will be zero
Do you agree with the statement, "An object with a zero velocity can have an acceleration greater than zero."? Explain your answer.
Zero velocity = No acceleration
Acceleration is changing velocity. Zero velocity means no motion. Zero acceleration means constant, unchanging motion.
An object moving in a circular path at constant speed will have a non-zero average speed and zero average velocity since velocity is a vector parameter,
Whenever velocity is constant, the acceleration is zero. This also works when the velocity is zero, the acceleration is zero. That pretty much means the object isn't moving. But, yes/ If velocity is constant, accleration is zero.
velocity may be zero or may not be zero i.e. if the object may continue to move with uniform velocity.
