Is it possible for an object to have zero velocity?
Zero relative velocity to another object, sure no problem. Zero absolute velocity, not possible as there is no absolute reference to compare to.
An object experiences a net zero external unbalanced force is it possible for the object to be travelling with a non-zero velocity?
what a stupid qn. ya it is possible
Can there be a body moving with constant acceleration but zero velocity. With examples?
since accelaration is the change in velocity of an object per unit time......if velocity is zero then there is no acceleration.its nt possible
Can constant velocity be zero?
Yes. Zero velocity is a velocity; if it is always zero then it is a constant velocity.
Is it possible that a body has zero speed and nonzero velocity?
No because velocity defined as speed in a given direction so if speed is 0 then velocity must also be 0
IS velocity possible in zero gravity?
Velocity is relative to the observer and or objects that are in the area , if your sitting in true zero gravity from your point of view you will be standing still but in-reality your velocity will based on your original thrust. Some one watching you (at a zero velocity) from another location might see you zoom by at the original velocity. So the new question is if that other person has zero velocity and is in zero gravity what time will it be when they look at their watch ? Hmmm
How is it possible for a car to have an average velocity of zero and an average speed of 65 mph?
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.
What hasa zero velocity yet a non-zero acceleration?
For example, an object thrown upwards, when it is at its highest point. This situation is only possible for an instant - if the acceleration is non-zero, the velocity changes, and can therefore not remain at zero.
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?"
Is it possible for the average velocity of an object to be zero during some interval even thought its average velocity for the first half of the interval is not zero explain and cite an example?
i think no
Is it possible for the average velocity of an object to be zero during some interval even thought its average velocity for the first half of the interval is not zero reexplain and cite an example?
yes
Is it possible in straight line motion particle have 0 speed and a non-zero velocity .explain?
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..
