How an object could still be moving with the 0 acceleration?
Zero acceleration means that the velocity doesn't change. It doesn't mean that there is no velocity.
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 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).
When velocity is zero and acceleration is less than zero does the speed increase?
if acceleration is <0 and velocity =0 then you got the handbrake on
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.
Can a body have 0 velocity and finite acceleration?
Yes.
How an object could still be moving with the 0 acceleration?
Zero acceleration means that the velocity doesn't change. It doesn't mean that there is no velocity.
The velocity of a body was noted to be constant during five minutes of its motion What was its acceleration during this interval?
Acceleration means speeding up or slowing down, a change in velocity. Since the velocity was constant, the acceleration was. 0

Does an object's speed increase even if acceleration decreases?
Acceleration is nothing but rate of increase in velocity. If acceleration at the time is positive velocity will increase independent of acceleration in past. Suppose you are moving at 5m/s at t=0. Acceleration is 5m/s2 initially. At t = 1 your velocity will be 10m/s. If acceleration became 3m/s2, then your velocity at t = 2 will be 13m/s. Thus your velocity still increased but comparatively lesser in amount. Now if acceleration became -8m/s2, velocity at t = 3 will be 5m/s, thus velocity decrease due to negative acceleration.
Does 0 acceleration means 0 velocity?
Not at all. Zero acceleration just means that the velocity is not changing ...the motion is in a straight line at a consgtant speed.
Why is the velocity 0 when your speed is constant?
It's not. If you speed is constant (but not zero), then your velocity won't be zero, either.You may be confusing this with the following: If your VELOCITY (not your speed) is constant, then your ACCELERATION is zero. Acceleration refers to how quickly velocity changes, so if velocity doesn't change at all, acceleration is zero.
If acceleration equals zero does velocity equal zero?
No.Any body traveling at a steady speed is experiencing velocity without experiencing acceleration. So a for particle traveling steadily at 3m/s, velocity equals 3 m/s, but as long as it travels steadily at this rate, acceleration is 0.
Can something have both a constant velocity and constant acceleration?
No it cannot. It is either one or the other. For constant velocity, acceleration must be 0, meaning there is no acceleration happening here. If there is constant acceleration, then the velocity is constantly changing.
