Can an object have a speed of 0 while it has an acceleration that is not 0?

Yes. Acceleration is independent of speed. A perfect example of an object with zero speed but nonzero acceleration is an object at the apex of being thrown upward. The entire time it is in the air it is accelerating downward. At its maximum height its speed is zero.

An example of zero acceleration would be what?
If you are moving at a speed of ceratin speed and there is no force trying to slow you down, and there is no force trying to speed you up. Then there is zero acceleration. An example would be : an object in out in space, if you throw a object away from you the object will float away, since there is no force working on the object after you throw it the object is moving away in a locked speed from you, but have zero acceleration because there is no force affecting the object
Can your speed be 0 while your acceleration non zero?
Yes, just as the acceleration is reversing your direction of movement.
When an object increases in speed what does the accleration vector do?
An object with an increasing speed is in fact accelerating, hence the acceleration vector may be continually changing (but >0) with time.
What is movement of a stationary object?
-- acceleration = 0 -- velocity (speed and direction) exactly equal to the observer's velocity
Why does an object at a constant speed have no net force?
If speed is constant, acceleration is zero. Anything multiplied by zero equals zero. F = m * a, where F is force, m is mass and a is acceleration. F = m * 0 = 0
How is am object moving at a constant speed and in a straight line like an object at rest?
An object moving at a constant speed in a straight line has an acceleration of 0. An object at rest also has an acceleration of 0. So, the two things I see in common are their accelerations, which are both 0.
Stationary objects are the result of?
0 velocity 0 acceleration The forces on the object are balanced: it is in equilibrium. (The forces are balanced on any object with 0 acceleration, even if it is moving.)
Does an object experiencing a constant velocity have a zero or non-zero value for acceleration?
If an object is sustaining a constant velocity it has 0 acceleration, because acceleration is either increasing or decreasing speed.

How do you find the height something fell from if you have the speed and mass of the object?
v^2 = v0^2 +2a*height v = speed v0 = starting speed (0 in this case) a = acceleration (9.8 is the acceleration of gravity) the speed of the object won't change based on the mass

Why does an object at a constant speed have no net force?
If speed is constant, acceleration is zero. Anything multiplied by zero equals zero. F = m * a, where F is force, m is mass and a is acceleration. F = m * 0 = 0
An object with constant velocity has positive acceleration?
Answer This occurs when an object istraveling in one direction but has an acceleration in the opposite direction, which means it is decreasing in speed. For a given period of time, the speed has decreased. Acceleration is the change of velocity per second. T1 = 5 seconds V1 = 100mph T2 = 10 seconds V2= 50 mph Acceleration = (V2 - V1 ) / (T2 - T1) = (50-100)/(10-5) = -10 ft/sec/sec Positive(+) acceleration means an object will be going faster over an interval of time.
Can falling object increase in speed and decrease in acceleration?
Falling object acceleration is due to gravity, and is therefore a constant. However, because there is a magnitude to this acceleration, the falling object will continue to increase in speed until it reaches its terminal velocity. We can also observe this quantitatively. Imagine that we have an object falling from a cliff. At initial, the velocity is 0, acceleration is -10 m/s^2(rounded for simplicity). After one second, we can calculate the velocity. V= V(o) + a(t) V = 0 +(-10)(1) -10 m/s. The speed is just the magnitude of the velocity, or + 10 m/s. To prove that it will increase even more in speed (even though it already from from 0 m/s speed to 10 m/s speed with negative acceleration), here's another example to further the point which expands on the problem already given. Let's evaluate speed at 2 seconds. V= V(o) + a(t) V= 0 + (-10)(2) V= -20 m/s. so speed = +20 m/s Hopefully you can see now that while velocity is decreasing, the magnitude of it, speed, is increasing, and that a falling object always has negative acceleration of about -10m/s^2.
What is the acceleration of a car moving at a speed of 50mph?
If the speed is constant at 50 mph, then the acceleration is 0.
