The acceleration of a body cannot be zero at a point where? The only way to solve this problem without using algebra is to understand that acceleration is the rate of change of velocity. The velocity is certainly zero at the topmost position.
After then, though, it changes for a little period of time. If the acceleration had been 0, the ball’s velocity would have remained constant and it would have remained in the air indefinitely.
Because there is movement “…velocity is decreasing,” it is the only response that guarantees that acceleration cannot be zero. There is a velocity change and hence the presence of an acceleration, regardless of whether it is negative or positive.
A continuous speed
When an object moves at a constant velocity, its acceleration might be zero. Because the velocity is constant, there will be no change in velocity, and so no acceleration.
When two forces of equal size but acting in opposing directions occur on the body, they cancel out and the nett force on the body is zero. As a result of Newton’s second rule of motion, we may state that the body’s acceleration must be zero.
The difference between velocity and acceleration is usually smaller. A point at which an object’s direction changes. Its velocity is zero at a turning point.
The following is a measure of how a body’s velocity varies over time: Acceleration.
When the acceleration is zero, the velocity does not change. If the object’s velocity remains constant (0 acceleration), it will continue to move forwards without slowing down or speeding up.
Yes, an item may have zero velocity while accelerating at the same time. Let’s take a look at an item that is going ahead.
point S. The ball’s velocity and acceleration are both zero at the highest point in its motion.
(1): The acceleration of a moving body is zero when the magnitude and direction of the velocity do not vary.
Yes, an item that was put in motion by a force in the past but is no longer being acted on by a nett force is still moving, but with no acceleration, i.e. at constant velocity.
There must be a change in velocity for anything to accelerate, since acceleration is defined as a change in velocity over time. To put it another way, if something is speeding up, it must have a changeable velocity. The acceleration is 0 if the velocity is constant (since the velocity does not change over time).
