When is a time where speed does not change but the object is still accelerating?

Acceleration is the time rate of change of velocity. Velocity is a vector. It has a magnitude ( speed ) and a directio. If either the speed or the direction of motion changes the object is accelerating. Example; an object moving in a circle at constant speed is accelerating because its direction is continually changing.

How can an object have zero acceleration?
i am ten so this will be a wimpy answer. it is an object that has nothing to propel it and therefor it has no acceleration. see wimpy Actually the above is wrong because an object can still be moving but it is accelerating only when there is a change in speed or direction. A car moving at a constant speed of 50 m/h is not accelerating however we can agree that it is still moving.
How can an object stay at same speed and still be accelerating?
acceleration is change in velocity over time. It is important to know that speed is not a vector quantity; it is scalar (meaning it does not have direction), -- velocity does. Therefore, speed is only the MAGNITUDE of velocity. Also, acceleration is a vector quantity meaning it has both magnitude and direction. If you change EITHER magnitude or DIRECTION, acceleration changes. Okay anyway to answer your question, You can have the same magnitude of velocity (aka same speed) and still be accelerating if YOU CHANGE DIRECTION. --- gh
Can a body have constant speed and still be accelerating give example?
Yes. The simplest example is an object moving at a constant speed in a circle.
When an object slows down it has no acceleration?
When an object slows down it is still accelerating.
If you constantly walk in a circle are you constantly accelerating?
Yes. That should only bother people who still think that 'accelerating' means 'speeding up'. It doesn't. 'Acceleration' means any change of speed or direction.
Accelation due to change in direction?
Acceleration is a change in velocity with respect to time. Velocity is a vector quantity, meaning it has both a direction and a speed. Acceleration is therefore also a vector quantity. So if you change the direction an object is moving without changing its speed, you are still accelerating the object.The best example of this is circular motion. If you tie a string to a rock and swing around your head at a steady rate, the speed of the rock stays the same but its direction is continually changing. It is accelerating, and the acceleration vector points directly to the center of rotation.
CAN AN Object accelerate and be moving at a constant speed?
Yes, it's direction may be constantly changing which would mean it is still accelerating.
Can a body have zero velocity and still be accelerating?
No. A velocity indicates a speed and direction. An acceleration is a change in speed or direction.
Is it possible for an object to be accelerating even after it has stopped moving?
Yes, a object can still be accelerating when the speed is zero, a classic example of which is throwing a ball straight up in the air, at the top of its trajectory it has an instantaneous velocity of zero while it is still accelerating towards the ground.
The velocity of an object can what if the speed of an object remains constant?
The velocity can still change, even if the speed doesn't. This is because velocity is a vector - not only the magnitude is important, but also the direction.
How can object accelerate when it does not change speed?
Let's review some terms before we tackle this one. Speed is displacement per unit of time. We know 60 miles per hour is a speed. Velocity is speed with a direction vector associated with it. We know 60 miles per hour east is velocity. Acceleration is a change in velocity. That means if an object changes its speed or its direction or both, it is accelerating.If an object has a given velocity and it slows down or speeds up, it is accelerated. But if the same object changes direction without a change in speed, it is still experiencing acceleration. A force had to act on the object to change its direction, even though its speed didn't change. Thus, an object can accelerate even though it does not change speed.
How is it possible for a car to be accelerating if its speed is a steady 65 mph?
The term accelerating means increasing in speed, so if a car holds its speed steady at 65 mph, it is not accelerating. It is still running its engine, to overcome air resistance and other forms of friction, but that is not the same thing as acceleration.
