Do you agree with the statement an object with a zero velocity can have an acceleration greater than yero?
Of course. Toss a stone straight up.
-- From the moment it leaves your hand until the moment it hits the ground,
it has constant acceleration ... the acceleration of gravity, around 10 meters
per second2. The number isn't important, only the fact that the acceleration
of the stone is not zero until it hits the ground.
-- Velocity-wise: The stone starts out with some upward velocity, which steadily
decreases until it's at the top of its arc, then the velocity becomes downward
and increases until the stone hits the ground.
-- At the very top of the arc, there is a point where the velocity changes from
upward to downward. In order for that to happen, there must be an instant
when the velocity is zero.
-- But the acceleration is constant and not zero, even at that instant when the
velocity is zero.
What else can I help you with?
Do you agree with the statement an object with a zero velocity can have an acceleration greater than zero?
Yes, an object with zero velocity can have an acceleration that is greater than zero if there is a change in its velocity over time. Acceleration is the rate of change of velocity, so even if the object starts with zero velocity, it can still accelerate if its velocity increases or decreases.
What does acceleration depends on?
Acceleration is change in velocity. So it depends on both velocity and time.
Do you agree with the statement an object with a zero velocity can have an acceleration greater than zero do you agree?
Yes. If it weren't so, an object that isn't moving could never be made to move at all! Of course, once you apply acceleration (which implies a change of velocity), the object's velocity won't stay zero. But for a brief instant, the velocity can be zero while accelerating.
Differentiate positive acceleration and negative acceleration?
A positive acceleration is a change in velocity such that the latter velocity is greater than the former velocity and is therefore going fasterwhile a negative acceleration or deceleration is a change in velocity such that the latter velocity is lesser than the former velocity and is therefore going slower.Now let us look at the equation of a uniform acceleration (the change in velocity is uniform):a = (vf-vi)/sIf the final velocity is greater, you will have a positive acceleration. If the initial velocity is greater, you will have a deceleration.
When does an acceleration becomes zero?
Acceleration being zero is equivalent to the statement that an object's velocity doesn't change.

Who has larger acceleration?
An object with a greater acceleration covers a larger change in velocity in a given time period compared to an object with a smaller acceleration. It is determined by the rate of change of velocity, with higher acceleration leading to a faster increase in speed.
Is acceleration greater when the object is thrown vertically or horizontally?
Acceleration is dependent on the initial velocity of how fast the object is leaving the projectile. The vertical acceleration is greater when the object is falling than when the object reaches the peak in height. However, if the object is thrown horizontally and there is no parabola in its shape then there is not as great of an acceleration.
What does the slope of a velocity vs time graph show you?
The rate of acceleration is a measure of the change of the velocity of an object with time. On a graph of velocity versus time, it is represented by the slope of the line so graphed. If velocity is changing in time, the object described is being accelerated. The greater the slope of the graph, the greater the change of velocity per unit of time and the greater the acceleration of that object. true
What is the force of acceleration?
The force of acceleration is the force that causes an object to change its velocity or speed. It is calculated using Newton's second law of motion, which states that force is equal to mass multiplied by acceleration (F = ma). The greater the force of acceleration applied to an object, the greater the change in its velocity.
What happens to a velocity when the acceleration changes?
If the acceleration changes, the velocity of an object will also change. If the acceleration increases, the velocity will increase. If the acceleration decreases, the velocity will decrease. The velocity and acceleration of an object are directly related.
Is there an acceleration when an object traveling at constant velocity and why?
No, there is no acceleration when an object is traveling at a constant velocity. Acceleration is the rate of change of velocity, so if the velocity is constant, there is no change and therefore no acceleration.
Is velocity the same as acceleration?
No, velocity and acceleration are not the same. Velocity is the rate of change of an object's position, while acceleration is the rate of change of an object's velocity.
