What is positive negative and zero acceleration is?
positive acceleration is when things speed up; negative acceleration is when things slow down; and zero acceleration is when things do not speed up or slow down, this is called constant speed, or no change in velocity.
For a car moving around a circular track at a constant speed the acceleration is?
constant speed=0 acceleration Acceleration is the change in speed. If the speed doesn't change(ie constant) the acceleration is zero.
What is does a horizontal line mean on a speed time graph?
It means the speed doesn't change. Stated in different terms, the acceleration is zero.It means the speed doesn't change. Stated in different terms, the acceleration is zero.It means the speed doesn't change. Stated in different terms, the acceleration is zero.It means the speed doesn't change. Stated in different terms, the acceleration is zero.
A car travels a highway 55 miles per hour what is its speed and acceleration?
Its speed is 55 mph, and if the highway doesn't curve, then its acceleration is zero.
What will the speed of the object at 6 second?
It'll be (speed at time-zero) plus (6 times acceleration).
Is your speed is constant if you are traveling in a straight line with an acceleration of zero?
If your acceleration is zero, then yes, you are traveling at a constant speed. The path does not matter. Acceleration measures the change in velocity, so an acceleration of zero means that there is zero change in velocity and therefore the speed is constant.
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
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.
Is it possible for your speed to be zero when your acceleration is not zero?
Yes. Zero acceleration means you are not changing your speed (speed up or slow down) or changing direction. Zero acceleration is a constant speed in a linear direction. A speed implies you are moving.
What is positive negative and zero acceleration is?
positive acceleration is when things speed up; negative acceleration is when things slow down; and zero acceleration is when things do not speed up or slow down, this is called constant speed, or no change in velocity.
What is the acceleration of an object that travels in a straight line at a constant speed?
The acceleration of an object moving in a straight line at a constant speed is zero. Acceleration is the rate of change of velocity, so if the speed is constant, there is no change in velocity and thus no acceleration.
Can an object be moving if acceleration is zero?
Yes. Acceleration is defined as a change of speed and/or direction of motion. If the speed and direction of motion are constant, then there is no acceleration.
Can your speed be 0 while your acceleration non zero?
Yes, it is possible for the speed to be 0 while the acceleration is non-zero. This occurs when the object is momentarily at rest (speed is zero) while still experiencing acceleration due to a change in its velocity.
Is it possible that there is a non-zero acceleration but with a speed of value zero?
Not with any sensible definition of "acceleration" and "velocity." You CAN accelerate an object and have it end up at zero velocity. But, if the acceleration remains a non-zero number, then the velocity can NOT remain at zero. Your question is like asking, "Can the value of a quantity change, but also remain the same?"
Can an object have a speed of zero and the acceleration not be zero?
Yes, but only at one instant. For instance, if you throw an object straight up, when it reaches the highest point its instantaneous speed is zero, but of course its speed is changing - thus, acceleration is non-zero.
For a car moving around a circular track at a constant speed the acceleration is?
constant speed=0 acceleration Acceleration is the change in speed. If the speed doesn't change(ie constant) the acceleration is zero.
Can it be possible that a particle have constant speed must have zero acceleration?
It's possible, but not necessary, that a particle moving with constant speedhas zero acceleration. In order for acceleration to be zero, it's also necessarythat the particle be moving in a straight line.An object moving with constant speed around a curve has acceleration."Acceleration" does not mean "speeding up".
