There are fundamental errors in the question.
A particle is three dimentional and cannot exist in a one dimentional universe, nor can velocity.
Yes. If the velocity doesn't change, there is zero acceleration.
Sounds like a trick question. The answer is no. Speed is a scalar with magnitude only and velocity is a vector with magnitude (speed) and direction. So If traveling with velocity in a straight line it has speed..
(ignoring the fact that there is technically no such thing as zero speed) Assuming that in both instances they are relative to the same reference frame, no it is impossible. velocity is speed in a given direction, if its speed is 0, it can never have a non zero speed in any direction. for example you could never say, that a car is not moving, but is moving north at 30m/s (well you could but you'd be wrong)
Velocity is speed together with its direction.Acceleration indicates a change in velocity ... speed or direction or both.Change of direction means acceleration, even if speed is constant.Constant velocity means constant speed and direction ... zero acceleration.
Yes - for example, if an object moves in a circle.
No. Acceleration is the change of velocity. If velocity is constant, at any speed, acceleration is zero.
Speed is distance by time and velocity is displacement by time. If an object is moving with speed distance can never be zero but displacement can. So we say velocity can be zero.
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.
Only for an instant. Acceleration is a change in velocity. When the derivative of acceleration with respect to time is zero, the velocity would be zero.
When an object is not moving. (Velocity is speed)
In that case, basically no force acts on the particle, and the particle moves at a constant speed. This constant speed may, or may not, be zero.
Velocity means speed. If something's speed is zero, it is standing still. If its speed is non-zero, it is moving, even if only very slightly.
Yes. F=ma if f is non zero then a is non zero and the velocity changes if the particle is not constrained, free to move.
Zero velocity means the object has no speed, that is, it's not moving. Zero acceleration means the object is moving with constant speed in a straight line, that is, its velocity is not changing.
An object moving in a circular path at constant speed will have a non-zero average speed and zero average velocity since velocity is a vector parameter,
"Uniform velocity" means zero acceleration, that is, constant speed in a straight line.rate of change of velocity is zero
If the car has an average speed of 65 mph, when it returns to its starting point, it will have a displacement of zero and an average velocity of zero, because velocity has both speed and direction.
If displacement of a particle is zero in a uniform circular motion, then the distance travelled by that particle is not zero, kinetic energy is constant, speed is constant and work done is zero
Velocity basically means how fast you are going. Acceleration means how much your speed is increasing. So if there is zero velocity that means the object is not moving. If there is zero acceleration, that means that the speed is not increasing but there is actual speed and the object is not increasing it's speed what ever that may be.
Yes, since velocity is speed and direction its average can be zero. For example say a plane flies from point A to point B at 300 mph and turns around to go from B to A at 300 mph; its average velocity is 0 since it is in the same spot as it started ( the velocity vectors cancel) but its average speed is 300 mph.
No. If the speed is always zero, then the average of its speed at any two points in time is also zero.
Yes. If the net force is not zero, the particle accelerates. Accelerate means the velocity changes,if the velocity changes the kinetic energy of the particle changes.
If the velocity equals zero, the acceleration is also zero because the velocity hasn't changed, thus, the particle isn't accelerating anywhere. This is not exactly true; at an instant in time the acceleration can be non-zero while the velocity is zero. However, this would change the velocity to non-zero after any amount of time. An example of this is when you throw a ball into the air: at it's highest point, the velocity is zero (it changes from going upward to going downward, passing through zero for an instant). However the acceleration is downward the entire time.
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.
Its acceleration is zero, which is constant
