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.

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).
A glider sailing across the sky at a steady speed and altitude an example of and unbalanced force?
No. A glider that is moving at a constant speed and in a constant direction is at a constant velocity. In other words it is not accelerating. Therefore, all forces on it must be balanced.
What is an example of an accelerating object but moves in a constant speed?
An accelerating object is one that is changing in either speed or direction. Thus any object that is turning is accelerating while maintaining a constant speed.
Can an objeact have constant speed and but variable velocity?
Speed is a scalar quantity while velocity is a vector quantity.It is possible that an object can have constant speed but if speed is constant while direction of motion is changing constantly then it means that body has variable velocity.An example of this phenomena is a body moving in a circle whose speed is constant but velocity is changing every instant due to change in direction at every instant.
If a force is exerted on an object is it possible for that object to be moving with constant velocity?
Velocity is a vector quantity in which both magnitude and direction must be taken into consideration. For an object to have constant velocity, it is necessary that both the magnitude and the direction of the velocity must be constant. Even if either magnitude or direction is variable, velocity will not remain constant. On the other hand, speed remains constant if direction is changed and magnitude is kept constant, as speed is a scalar quantity.For an object to have constant velocity, it is necessary that the object move at a constant speed and not change course. That object must move in a straight line to have a constant velocity.
What is an Example of constant velocity?
constant velocity means the speed and direction are the same.
What is nature of velocity in constant speed?
Velocity magnitude is unchanging at constant speed. The direction might change (velocity is a vector with both size (speed) and direction) if , for example, you are driving around a curve at a constant speed.
What is an example of constant speed with changing velocity?
Velocity is a vector, thus it has a direction. Therefore, you can change the velocity by changing direction. A great example of this is a ball on a string spinning at a constant speed, but it is continually changing direction, therefore, even though the speed is constant the velocity changes at every instant.

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).
If you know that a moving object has a constant velocity you can predict correctly where it will be after a given amount of time. however if you know only that the object has a constant speed you cann?
For constant velocity,which means constant speed and constant direction, you predict where it will be after a given amount of time. For constant speed,which means you do not necessarily know direction, you cannot predict where it will be after a given amount of time, since direction can be changing. Speed is a scalar and velocity a vector.For example of a car is traveling in a circle you cannot tell where it will be in time unless you know the direction change and the radius of the circle for example. If a baseball is thrown to home plate by the pitcher at a speed of 90 mph, in a straight line, now you know speed and direction and if both constant then velocity is constant.
What is the difference of constant speed and changing velocity?
Constant means that something doesn't change; "changing" means that it does. Speed is a magnitude - measured (for example) in meters per second. Velocity, on the other hand, is a vector - which means that the direction is also considered. If an object changes direction - for example, moving in a circle - it is possible to do so at a constant speed. However, since the direction changes, the velocity will - by definition - change.
What is an example of something at constant speed but not constant velocity?
You are driving your car with cruise control but you steer around a bend in the highway. The cruise control keeps your speed constant, but by steering you change your direction and thus your velocity is not constant.
What is centripetal acceration in physics?
That means acceleration towards the center. For example, this happens any time something moves in a circle.
example of a change in acceleration while travelling at constant speed?
An example of a change in acceleration while traveling at constant speed can be observed when a vehicle moves in a circular path or takes a turn. Although the speed remains constant, the direction of the motion changes, which results in a change in velocity. Since acceleration is the rate of change of velocity, this alteration in direction causes a change in acceleration, even when the speed is constant.
Can an object have a constant speed and a varying velocity?
Yes. Velocity is a quantity that has both magnitude and direction. Speed is the magnitude of velocity. If speed is constant but the direction is changing, then the velocity is changing. An example is a car turning a corner without slowing down.
Can a body have constant velocity when it has constant speed?
Of course. In fact, in order to have constant velocity, it must have constant speed.What you really want to know: Can a body have changing velocity when it has constant speed ?The answer to that one is also "yes", for example when it is moving in a circle, the speed is constant but the velocity is changing all the time (in direction).
A glider sailing across the sky at a steady speed and altitude an example of and unbalanced force?
No. A glider that is moving at a constant speed and in a constant direction is at a constant velocity. In other words it is not accelerating. Therefore, all forces on it must be balanced.
