The object is moving in a path that keeps curving. Since its speed

(magnitude of velocity) is constant, its path would be circular.

An object in circular motion is constantly acceleratingtrue or false?

True. It is accelerating because the velocity constantly changes. The velocity constantly changes because the direction changes - and a velocity is made up of a magnitude, and a direction.True.

If velocity dSdt and speed dSdt then what happened when a body move in a complete circle were dS0 then velocity?

Velocity is a vector, meaning it has a direction, like east, north, up. Speed isa magnitude without direction, 60 miles per hour is a speed; 60 miles per hour north is a velocity. When a care is going 60 mph in a circle the speed is constant but the velocity changes as the direction changes. The magnitude of the velocity is the same but the direction changes thus the velocity changes. Velocity changes if either the speed/magnitude or the direction change.


Why is the velocity of the car traveling in a circle changing?

That's because the direction changes. In physics, "speed" is a scalar, while "velocity" is a vector - i.e., both the magnitude and the direction matter. In the case of velocity, if either the direction or the magnitude change, that means that the velocity changes.


Determine whether you are accelerating as earth rotates once every 24 hours?

Yes. Since the direction of the movement changes, that means there is an acceleration. Remember, acceleration is a change in velocity; velocity includes both a magnitude and a direction.Yes.

An object traveling in a circle is accelerating because it is constantly changing?

An object traveling in a circle is accelerating because it constantly changes its direction even though the velocity may or may not change in magnitude.


What happens to an object's velocity when it accelerates?

"Acceleration" implies that the velocity changes.


Does velocity of an object remain constant in uniform circular motion?

Velocity is a vector with magnitude (speed) and direction. Since the linear velocity changes direction the speed is constant but the velocity is NOT constant.


How can acceleration change the magnitude and direction of the velocity?

Velocity is speed in some direction. Acceleration changes that speed or that direction (or both).


How is circular motion accelerated motion?

"Acceleration" means a change in velocity. And "velocity" is a vector - meaning that not only the magnitude, but also the direction is relevant. So, if the direction of the movement changes, the velocity changes by definition, even if the MAGNITUDE of the velocity (also known as "speed") doesn't change.


Does it possible the speed will be the same at different velocity?

Yes, if you want to get technical about it. 'Velocity' is a quantity that has both magnitude (size) and direction. The magnitude of the velocity is what we call the speed. Strictly speaking, you can change the 'velocity' by changing only its direction. When that happens, the velocity has changed, but the speed hasn't. A perfect example is a race car doing a steady 150 mph on a circular track. The velocity is changing CONSTANTLY, but the speed NEVER changes.


How does change in force effect the direction velocity and acceleration of an object?

Changing the magnitude or direction of forces exerted on an object changes the net force (sum of all forces) exerted on the object. The net force exerted on an object is defined as mass times acceleration (F = ma), where mass, m, is constant. This means that when the net force exerted on the object changes in magnitude (or direction), its acceleration will also change in magnitude (or direction). In addition, acceleration is defined as the change in velocity, so when the magnitude (or direction) of acceleration changes, the magnitude (or direction) of velocity will also change.


Are satellites an example of acceleration as it orbits around the earth?

Yes. Since the velocity changes all the time, there is an acceleration. The acceleration is towards the center of the Earth. Note that the speed need not change; velocity consists of a speed (magnitude) and a direction, and in a circular orbit, it is the direction that changes.Yes.

What is the relationship between accerleration and velocity?

Acceleration is the rate of change of the magnitude of velocity and the direction in which the velocity changes.


When is velocity said to have changed?

A complete statement of velocity consists of speed (magnitude) and direction. If either the speed or direction of motion changes, then velocity has changed.


What control on a car change its velocity?

-- Gas pedal (increases magnitude of velocity)-- Brake pedal (decreases magnitude of velocity)-- Steering wheel (changes direction of velocity)


Why is an object traveling in a circular motion accelerating?

acceleration is change in velocity.. and velocity constantly changes in circular motion, as the direction constantly changes. This constant change in velocity causes the object to accelerate.


How circular velocity is constant in circular motion?

Velocity constantly changes as so does the direction around a circle...


Why the speed of an object is constant while the velocity is not?

This is not always the case. But if an object moves in a circle, at constant speed, its velocity will change. Velocity is a vector - consisting of the magnitude (the speed), and a direction. So by definition, if the direction changes, the velocity changes - you have a different vector.


What is an example of concentric motion?

Example: Moon revolving around the sun (although it's technically elliptical not perfectly circular) -speed is constant but velocity changes constantly since the vector changes direction but not magnitude.


What is the change in velocity of the motion of an object i?

The change in velocity is just the change in velocity. The RATE of change of velocity - how quickly velocity changes - is usually called "acceleration".


Can something keep a constant velocity in a curve?

No. It can keep a constant SPEED in a curve. But if the direction changes, then that's a change of velocity, and the direction in a curve is constantly changing.


When a vibration is at maximum displacement what is its velocity?

Zero. That's the instant at which its velocity changes direction. In order to do that, its magnitude has to be zero at that point in time.


Can uniform velocity appear in circular motion?

No.. this is impossible. Velocity must have a constant direction and speed to remain constant, it may have a constant speed, but the direction in a circle constantly changes. If it suddenly were to have constant direction, then the motion would go off on a tangent.. making it linear motion, not circular. In circular motion, velocity constantly changes. Always.


Why does direction change when you change velocity?

Direction does not have to change when velocity is changed. You can move North at 10 m/s and change it to 8 m/s a second later. You would still be moving North. But since velocity is a vector, if direction changes, even though speed (magnitude of velocity) remains constant, then velocity most certainly changed, since both magnitude and direction make up the vector.


What changes in motion can result in a change in velocity?

Any change in motion (direction or speed) is a change in velocity.Velocity is a vector quantity which means that it has a magnitude and a direction.
