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.

If an object is moving in a negative direction, but with positive acceleration. For example: Backing up a car, while coming to a stop. The car is moving in a relative negative direction(back of car), while the acceleration is in the positive direction(front of car).

False. An object at constant velocity is at zero or no acceleration. Of course, if the acceleration is always 0, then it is a constant acceleration of zero.

When velocity is positive and acceleration is zero what happens to an objects motion?

When acceleration is zero, then the object is moving in a straight line with constant speed. (That's the effective meaning of constant velocity.)


What is an object that moves with constant position?

An object that moves with constant position will have constant velocity or acceleration. This is said to be moving in positive direction and maintains the position.


Can an object traveling at constant velocity have acceleration?

No. An object traveling at a constant velocity is not accelerating.


Is there an acceleration when an object traveling at constant velocity and why?

No. Acceleration is change of velocity / time. If there is no change in velocity, there is no acceleration.


Can an object traveling at constant velocity have acceleration why?

If a velocity or speed is constant there isn't an acceleration. This is because the acceleration is the change in speed or velocity and if it's constant then there sn't a change.


Can an object be accelerating if it has constant velocity?

No. The definition of acceleration is the change in an object's velocity over time. Acceleration must then be zero since velocity remains constant.


When the acceleration of an object is zero what is the velocity at the same time?

As long as acceleration is zero, the object's velocity is constant.


Can an object have zero velocity and nonzero acceleration?

Yes. An object moving at constant velocity has zero acceleration. The constant velocity van be any constant including zero velocity. Mathematics acceleration a=dv/dt = 0. Solving this gives v = constant.


If an object falls with constant acceleration the velocity of the object must?

Changing at a constant rate equal to acceleration.


An object is falling at its what if it falls at a constant velocity?

rate of acceleration


If an object moves with constant acceleration what happens to the velocity?

The velocity increases at a constant rate.


An object with a constant acceleration but with zero velocity what is mean is n't possible.?

Yes, it can happen. when the velocity is momentarily zero while an object is changing from moving in the positive direction motion to the negative direction; the object obviously will stop at one point, but will still have a constant acceleration.
