Yes, a body can have zero velocity and still have acceleration if its speed changes directions while its magnitude remains constant. This situation occurs when an object is moving in a circular path at a constant speed. The change in direction of velocity due to the circular motion results in centripetal acceleration.
What else can I help you with?
Can a body have constant acceleration and zero velocity?
Since the derivative of velocity is acceleration, the answer would be technically 'no'. Here is why: v = 0 v' = 0 = a Or in variable form... v(x) = x v(0) = 0 v'(0) = 0 = a You can "trick" the derivative into saying that v'(x) = 1 = a (since the derivative of x = 1) and then stating v'(0) = 1 = a... but that is not entirely correct. Acceleration is a change over time and is measured at more then one point (i.e. the acceleration of this body of matter is y from time 1 to 5) unless using derivatives to form the equation of the acceleration line/curve. If an object has a constant acceleration of 1, then the velocity is constantly increasing over that time. Using the equation discussed above and looking at acceleration over time, at 0 seconds, acceleration is 0 and so is velocity, but from 0-1 seconds acceleration is 1 and velocity is 1 as well. 0-2 seconds, acceleration is 1, but velocity would be 2 (at the end of 2 seconds).
Can a body be in motion but 0 acceleration?
Yes, a body can be in motion but have zero acceleration if it is moving at a constant speed in a straight line. Acceleration measures the rate of change of velocity, so if velocity is constant, acceleration is zero even though the body is in motion.
When acceleration is 0 why does velocity have to be at a maximum?
It doesn't. If acceleration is zero, that just means that velocity isn'tchanging ... the motion is in a straight line at a constant speed.
How an object could still be moving with the 0 acceleration?
An object can still be moving with zero acceleration if it is moving at a constant velocity. When acceleration is zero, the object's velocity remains constant, meaning it continues to move at the same speed and in the same direction without any change in speed or direction.
If an object is moving at a constant velocity what do you know about its acceleration?
"Acceleration" means change of velocity. If velocity is constant, then acceleration is zero.
Can a body have 0 velocity and finite acceleration?
Yes.
The velocity of a body was noted to be constant during five minutes of its motion What was its acceleration during this interval?
The acceleration of the body was zero during this interval because its velocity was constant. Acceleration is the rate of change of velocity, so if the velocity does not change, the acceleration is zero.

Is 0 velocity and 0 acceleration correctly describes the velocity and acceleration of the rock at the exact top of its path?
No. Any object that was shot by gun, flung by slingshot, or thrown by hand, begins accelerating downward at the acceleration of gravity as soon as it leaves the propulsion system. Zero velocity is true at the top, but acceleration is constant throughout the trajectory ... 9.8 m/s downward.
What is the value of acceleration when a body moves uniformly?
When a body moves with uniform, its acceleration is is constant if v(m/s) t(s) a(m/s2) 4 1 0 8 2 4 12 3 4 16 4 4 (8-4/1)=4 12-8/1=4 hence acceleration is constant.
What would be the acceleration of a body if its velocity time graph is a line parallel to the time axis?
If the velocity-time graph is a straight line parallel to the time axis, it means the velocity is constant. The acceleration would be 0 because there is no change in velocity over time.
Is it impossible when an object moving in a straight line has no acceleration?
Yes, if an object is moving in a straight line and has no change in its speed or direction, then it has no acceleration. Acceleration is the rate of change of velocity, so if the velocity is constant, the acceleration is zero.
What is the acceleration of a body which starts from rest and travels 87.5 m in 5 seconds?
The acceleration of the body can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. Since the body starts from rest, the initial velocity is 0 m/s. The distance traveled is 87.5 m in 5 seconds, so the final velocity can be calculated using the formula: final velocity = distance / time. Plugging in the values, we get final velocity = 87.5 m / 5 s = 17.5 m/s. Now, using the acceleration formula, we get: acceleration = (17.5 m/s - 0 m/s) / 5s = 3.5 m/s².
