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).

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.


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.


How can acceleration occur when speed is constant?

Acceleration is the rate of change of velocity. Even if an object's speed is constant, acceleration can still occur if the direction of the object's motion changes. For example, when an object moves in a circle at a constant speed, it is undergoing acceleration towards the center of the circle due to the change in its direction of motion.


Is motion with constant velocity an example of motion with constant acceleration?

Well, technically yes, and we even know the magnitude of the constant acceleration.If velocity is constant, that tells you that acceleration is zero, which sounds likea constant to us.

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.

How do you find rate of acceleration when only given constant speed?

"Acceleration" is usually understood, by most people, to mean the rate at which speed changes. Technically, that's wrong. But if that's the level you're operating at, then "constant speed" means zero acceleration, and you're done. Acceleration is really a combination of the rate at which speed is changing and the direction in which it's changing. For example, a model car racing around a circular track at a constant speed has acceleration because its direction is constantly changing. If you're working at that level, then "constant speed" doesn't tell you everything you need to know in order to determine acceleration completely. You also need complete information that describes everything that's happening to the direction.


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.


How can acceleration be constant if it is an increase in speed?

Exactly the same way that the speed can be constant but the distance keeps increasing.If the acceleration happens to be an increase in speed, then "constant" accelerationmeans that the speed will increase just as much in the 7th minute, for example,as it increased in the 4th minute, for example, etc.Acceleration can be the rate at which speed changes. So if the acceleration is constant,then the speed is changing at a constant rate.(Note: Acceleration doesn't have to be a change of speed. It can also be a changeof direction, at constant speed.)


Can an object have zero velocity and nonzero acceleration?

Yes, an object can have zero velocity and nonzero acceleration. This occurs when the object is changing its direction but not its speed. For example, in circular motion, the object's velocity is constantly changing direction, leading to a nonzero acceleration even when its speed is constant.


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.


How can you be accelerating and traveling at a constant speed?

Acceleration refers to any change in an object's velocity, which includes changes in speed or direction. It is possible to have a constant speed while still accelerating if the direction of motion changes, for example, when moving in a circle at a constant speed. So, while the speed remains the same, the change in direction constitutes acceleration.
