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).
An object with constant velocity has no acceleration.
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.
No. An object traveling at a constant velocity is not accelerating.
No. Acceleration is change of velocity / time. If there is no change in velocity, there is no acceleration.
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.
No. The definition of acceleration is the change in an object's velocity over time. Acceleration must then be zero since velocity remains constant.
rate of acceleration
When acceleration is zero, then the object is moving in a straight line with constant speed. (That's the effective meaning of constant velocity.)
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.
No. An object traveling at a constant velocity is not accelerating.
No. Acceleration is change of velocity / time. If there is no change in velocity, there is no acceleration.
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.
No. The definition of acceleration is the change in an object's velocity over time. Acceleration must then be zero since velocity remains constant.
As long as acceleration is zero, the object's velocity is constant.
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.
Changing at a constant rate equal to acceleration.
rate of acceleration
The velocity increases at a constant rate.
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.
