Which example describes constant acceration due only to a change in direction?
Centrepetal force-orbits E.G. Earth orbits the sun at a constant speed but also changes its direction, thus its velocity. This means that the almost constant change in velocity causes there to be a constant acceleration because of the change on direction.
At what points does velocity change direction?
The velocity of an object can only change if it is accelerating and if this is constant and continuous. Velocity will also only change direction if acceleration is greater than zero and will not work if at zero.
What do you call it when an objects velocity changes?
A change in an objects velocity is called acceleration. Velocity is defined as an objects speed of travel AND its direction of travel. Acceleration can change only an objects speed, only its direction or both. If there is no acceleration acting on the object, then the velocity remains constant.
Can two directions 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.
Which example describes constant acceleration due only to a change in direction?
In physics, acceleration is defined as a change in velocity. Velocity is the measurement of the rate (or speed) and direction of an object. Therefore, an object is "accelerating" when it changes direction while maintaining the same rate (or speed).
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.

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.
A cyclist goes around a level circular track at constant speed. Is the cyclist's acceleration zero because her speed is constant?
No. The cyclist is moving at a constant speed, but her velocity is changing. Remember that velocity is speed with a direction vector associated with it. As speed is constant, only direction is changing. But a change in direction is a change in velocity (even if speed is constant), and this requires acceleration in that direction to accomplish the change in direction. You're on the right track, but just recall that acceleration is tied to velocity and not just speed. And note that velocity can change all the time without speed changing. Acceleration must cause the change in velocity. Consider that objects in orbit around the earth move at a pretty constant speed, but accelerate toward the earth all the time. Their speed coupled with their acceleration toward earth cause them to move in an arc - which is their orbital path.
What makes velocity different from acceleration?
Acceleration is the change of speed upward. Velocity is any speed, in a fixed direction. So the diference, is that in speed; the direction can change, but the speed remain constant. Only if it moves faster or slower dose the speed change. So in velocity, if the speed, or the direction change, then the velocity changes.
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.
Why does an object in uniform circular motion exhibits acceleration when its speed is constant?
Acceleration is defined as the change in velocity divided by the time ora = (vf - vi)/tVelocity measures the speed and the direction of an object.In uniform circular motion, the object has the same speed but it is always changing direction and so, by the definition of acceleration, the object is considered accelerating. If this acceleration doesn't exist, the object would move in a straight line according to Newton's laws of motion.
Can an object moving at a constant speed have acceleration?
Acceleration is defined as the change in velocity over a given time period. Velocity is a vector quantity: it includes speed and direction. That being said, you can accelerate an object without changing its speed by simply changing its direction. A body moving along the circumference of a circle its speed may remain a constant, but its velocity will not be a constant since its direction of motion continuously changes, since the velocity changes it has an acceleration.
