Acceleration is change of velocity. If velocity is constant ...
"no change" ... then acceleration is zero.
The velocity increases at a constant rate.
It velocity is constantly increasing, v=vo + at.
An object in uniform circular motion undergoes constant acceleration but moves at constant "speed".Constant "velocity" means no acceleration.
'Constant velocity' means constant speed in a straight line.That's also a good definition of zeroacceleration.
An object that moves with constant position will have constant velocity or acceleration. This is said to be moving in positive direction and maintains the position.
The acceleration of an object with constant velocity is zero. It's force will be Mv^2 where M is it's mass and v is it's velocity.
An object moves with constant velocity when there is no net force acting upon it. If there are no forces acting on an object, or if the forces acting on it "cancel out" leaving a net force of zero acting on the object, it will have zero acceleration. With a zero acceleration, the velocity of the object will be constant.
It moves with a constant acceleration downwards. This means that its velocity is increasing at a constant rate.
When an object moves in a circular path, the velocity will change and the there will be acceleration.
There is only acceleration if the car's velocity changes. If it moves at a constant velocity, then there is no acceleration.
An object moving with uniform acceleration has a uniform change in velocity over time, and its velocity-time graph will be a straight line with either a positive or negative slope. An object moving with no acceleration has constant velocity, and its velocity-time graph will be a straight, horizontal line with zero slope. Refer to the related link for illustrations.
Yes. Velocity implies both a magnitude and a direction. An object going around in a circle moves at a constant speed, but the direction, and therefore the velocity, is changing.Yes. Velocity implies both a magnitude and a direction. An object going around in a circle moves at a constant speed, but the direction, and therefore the velocity, is changing.Yes. Velocity implies both a magnitude and a direction. An object going around in a circle moves at a constant speed, but the direction, and therefore the velocity, is changing.Yes. Velocity implies both a magnitude and a direction. An object going around in a circle moves at a constant speed, but the direction, and therefore the velocity, is changing.
If an object's velocity is constant, then its acceleration is zero.If acceleration is zero, then the NET external force on the object is zero.There may be forces acting on it, but they're canceling, so the NET force is zero.
It means that the object moves in a straight line at a constant speed.
In Simple motion, there is no force being applied. The moving object moves in a straight line with constant velocity. In acceleration, there is a force applied. The object's velocity is changing. The first derivative of acceleration is velocity. The first derivative of velocity is distance. (Derivative is a calculus thing.)
Observe that the object below moves in the negativedirection with a changing velocity. An object which moves in the negative direction has a negative velocity. If the object is speeding up then its acceleration vector is directed in the same direction as its motion (in this case, a negative acceleration).
If the net force on an object is zero, then velocity of the object is constant ... it moves in a straight line at a constant speed.
Yes an object can be accelerate if its moving along a curve path because when the object moves along a curve path it has constant speed and there is still change in velocity and change in velocity has acceleration
Constant velocity means that the object's speed is constant, and it moves in a straight line, i.e. the direction of its motion is also constant. When an object moves in a manner consistent with this description, probability dictates that sooner or later, it bumps into something.
Answer Both refer to an object that is in a cirular motion. Radial Acceleration is a velocity change of the object as it moves away from the center of rotation. Tangential Velocity is a change of velocity of the object as it moves in a line that is tangential to the circular path it is moving.
Yes. A typical case is when an object moves at a constant speed in a circle.
It is called constant velocity. Rate is just another word for velocity. This, however, is dependant upon the path the object is taking. If it is moving in a parabolic path, or a curve of some sort (anything but a straight line), then the object is actually accelerating (as acceleration is a change in velocity OR direction.)
No. If it its moving at constant velocity, its instantaneous velocity would be the same as its constant velocity.
When an object is moving upwards, its velocity is directed upwards. If the object is near the Earth or any other planet, then its acceleration is directed downwards, which also means that its upward velocity is decreasing.
