Can an object reverse its direction while maintaining a constant acceleration?
One answer to this is that all object are in motion all of the time relative to all other objects. With that said, in the context of permanent halt" the only way that an object can be perceived as "halted" is by another object with the same velocity.
An object with constant velocity has positive acceleration?
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.
Can the velocity reverse the direction when acceleration is constant?
Yes, it can, if the initial velocity vector of an object was in opposite direction to its constant acceleration. Example: Anything you toss with your hand has constant acceleration after you toss it ... the acceleration of gravity, directed downward. If you toss it upward, it starts out with upward velocity, which reverses and eventually becomes downward velocity.
How does positive and negative acceleration affect motion?
positive acceleration helps to increase the velocity for positive direction while negative acceleration resists the motion.
Is uniform circular motion and circular motion is the same?
no, in uniform circular motion the magnitude of your velocity, and therefore your acceleration is constant. in general this does not need to be true. consider this simple experiment, in a children's playground, go to a roundabout. stand on the roundabout and kick once, then wait for your motion to completely stop before kicking again. your motion is still circular, but neither velocity or acceleration is constant.
Does the speed of a ball increase or decrease after it hits the ground?
Once a ball has fallen a distance through the air, and it contacts the ground, its speed will rapidly decrease until it has stopped moving. The acceleration experienced by the ball is so great that it seems to stop instantly. Most likely, it will bounce back up, and then repeat this cycle a few times before coming to rest.
When entering an expressway never stop in the acceleration lane unless traffic is?
When entering an expressway, never stop in the acceleration lane unless traffic is stopped. This would cause an accident if the traffic was not moving and a persons car was continuing to accelerate.
What causes bucking during acceleration?
Bucking during acceleration can be caused by a low fuel level. When the car is running on fumes, it is not getting a constant supply of gas which will cause it to stop and go.
How far in meters does a person travel in coming to a complete stop in 36 rm ms at a constant acceleration of 60g?
The answer will depend on the measurement units used for 36 (time?) and the units for acceleration.
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.
What is the future perfect of stop?
The future perfect of stop in English is "will have stopped." I will have stopped you will have stopped he/she/it will have stopped we will have stopped you will have stopped they will have stopped
What if the earth stopped rotating?
we'd all die because we would feel earth stop rotating . because we can only feel acceleration and stopping

What does halte mean?
to stop or be stopped.

If a car traveling 30 miles per hour can stop in 50 feet how many feet will it take the same car to stop when it is travelling 20 miles per hour?
If there is constant acceleration and deceleration then it would be 33.3 ft to stop
Summary of Holt integrated science level green?
organizer for a car that stars from one stop sign and aproaches the next stop sign, use tis terms constant velocity,positive acceleration,deceleretion and at rest.
