How can a car accelerate if its speed is constant?

It can Accelerate by changing it direction as acceleration eing a vector is dependant on the direction so by changing its direction one can accelrate it keeping the speed constant.


Can two direction of velocity of an object change when acceleration is constant?

An object can have only one velocity at any point in time. That velocity can have components in two (or more) directions.If acceleration is constant (but non-zero), then the velocity in any direction other than perpendicular to the direction of the acceleration must change.


Can an object acceleration if its velocity is constant?

No. It is a matter of definition. Acceleration is defined as a change of velocity. Technically, one must distinguish between velocity and speed. Velocity is a vector and includes the information about the magnitude (speed)and direction. One can have a constant speed and an acceleration (as in circular motion) but, by definition, constant velocity means zero 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.


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.


What is the acceleration of a car that is travelingin a straight line at a constant speed?

You are supposed to divide the change in velocity, by the time. In this case, the change of velocity is zero. Divide that by any time, and you get zero.Answer 2The acceleration is zeroIf the speed and direction of an object is constant, then the acceleration is zero m/s2The acceleration is defined as the velocity change per time ratio.Accelerating means increasing speed. The only way one can accelerate and travel at a constant speed is when he is changing his direction, that is, moving in a circle. This is because acceleration is the rate of change of velocity. Velocity means speed with a direction. So if the speed is kept constant, the direction has to change for acceleration.Refer to link below for more information and for more examples.


Can something have both a constant velocity and constant acceleration?

No it cannot. It is either one or the other. For constant velocity, acceleration must be 0, meaning there is no acceleration happening here. If there is constant acceleration, then the velocity is constantly changing.


How do you measure constant velocity?

Constant velocity is, well, constant. To measure it, measure the displacement through a given or fixed period of time. You'll have distance and time. Distance per unit time is speed. Distance per unit time (speed) with a direction vector is velocity. Velocity is speed in a given direction. If something is moving at constant velocity, it is moving at a constant speed in one direction. No changes in speed (no positive or negative acceleration, or, said another way, no acceleration at all), and no change in direction or heading.


If a body is moving with constant velocity is it moving with constant acceleration?

An object moves with constant velocity when there is no net force acting upon it. If there are no forces acting on an object, or if the forces acting on it "cancel out" leaving a net force of zero acting on the object, it will have zero acceleration. With a zero acceleration, the velocity of the object will be constant.


What must cause acceleration when a car is moving a constant speed and why?

Acceleration is scientifically defined as a change in velocity, not an increase in speed. Thus slowing down, speeding up, or changing direction are all forms of accelerating. If one is moving at a constant speed, then the only way to accelerate would be to change direction.
