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).
What is an example of an object moving at constant speed and constant velocity?
An object moving in a straight line at a speed of 50 km/h with a constant velocity of 50 km/h in the same direction is an example of constant speed and constant velocity.
How can a car accelerate if its speed is constant?
A car can accelerate even if its speed is constant by changing its direction or increasing its velocity. For example, if a car is moving in a circle, it is constantly changing its direction, resulting in acceleration. Additionally, if a car is moving at a constant speed and then speeds up, it is also accelerating.
Can an object be accelerated if it is moving with constant speed if yes explain giving examples?
Yes, an object can be accelerated even if it is moving at a constant speed if the direction of its velocity changes. This change in velocity, even if the magnitude of speed remains constant, indicates acceleration. For example, if a car is moving around a circular track at a constant speed, its direction is changing constantly, resulting in acceleration.
Why is circular motion an example of constant acceleration?
Actually it isn't. In circular motion, even if you assume a constant speed (the simplest case), acceleration is towards the center. Therefore, the direction of the acceleration changes all the time - and therefore, the acceleration changes all the time.
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.
What is an example of an object moving at constant speed and constant velocity?
An object moving in a straight line at a speed of 50 km/h with a constant velocity of 50 km/h in the same direction is an example of constant speed and constant velocity.
How can a car accelerate if its speed is constant?
A car can accelerate even if its speed is constant by changing its direction or increasing its velocity. For example, if a car is moving in a circle, it is constantly changing its direction, resulting in acceleration. Additionally, if a car is moving at a constant speed and then speeds up, it is also accelerating.
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.
Can an object be accelerated if it is moving with constant speed if yes explain giving examples?
Yes, an object can be accelerated even if it is moving at a constant speed if the direction of its velocity changes. This change in velocity, even if the magnitude of speed remains constant, indicates acceleration. For example, if a car is moving around a circular track at a constant speed, its direction is changing constantly, resulting in acceleration.
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.
Why is circular motion an example of constant acceleration?
Actually it isn't. In circular motion, even if you assume a constant speed (the simplest case), acceleration is towards the center. Therefore, the direction of the acceleration changes all the time - and therefore, the acceleration changes all the time.
Is a person running in a circular track at 7mph an example of constant velocity at zero acceleration and if so why?
Yes, a person running in a circular track at a constant speed of 7mph is an example of constant velocity and zero acceleration. While the person is changing direction, their speed remains constant, resulting in a steady velocity. Acceleration would only occur if there were a change in speed or direction.
What is centripetal acceration in physics?
That means acceleration towards the center. For example, this happens any time something moves in a circle.
