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

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

"Acceleration" implies that the velocity changes.


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.

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.


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.


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


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


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.


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


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


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.

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.


"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.


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.


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.


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.


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.


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


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.


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.


Acceleration is the change in velocity of an object over time. Take note that velocity is a vector quantity which means that it has magnitude and direction...Thus...An object undergoes acceleration when:1. there is a change in the magnitude of the velocity (speed) of an object.2. there is a change in direction of an object.3. it changes both in direction and magnitude.


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.


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.


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


Velocity is the rate at which location changes, and the direction in which location changes. Acceleration is the rate at which the size of velocity changes, and the direction in which velocity changes.
