Is a car moving around a curve without changing speed accelerating?

Yes. Even though its speed doesn't change, its velocity does change, therefore it is accelerating.

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.
Is it possible for an object to be accelerating even though it has stopped moving?
No. A nonzero acceleration means that the velocity is changing, so it can only have a 0 velocity at a single point in time, such as when a ball thrown in the air reaches its peak.
What must cause acceleration when a car is moving a constant speed and why?
Acceleration is scientifically defined as a change in velocity, not an increase in speed. Thus slowing down, speeding up, or changing direction are all forms of accelerating. If one is moving at a constant speed, then the only way to accelerate would be to change direction.
Would you consider a car turning around a corner at a constant speed to be accelerating?
It depends on which direction you are resolving the acceleration from. If you use the original direction of the car as it turns it is decelerating as the speed it is moving in that direction is decreasing. If you resolve from the direction which the car will be going towards then it is accelerating as its speed in that direction is increasing.
By how much does the speed of a vehicle moving in a straight line change each second when it is accelerating at 2kmhs?
2km/h
Is a jogger moving at a constant speed accelerating?
No. An object is accelerating if it is changing speed or direction of travel. Since the person in question is running at a constant speed in a straight line, they are not accelerating.
How can you say that object is accelarated?
If the object's speed is changing, or it's not moving in a straight line, then it's accelerating.
Describe a situation in which the car has zero speed but has a definite acceleration?
An object moving at constant speed in a circle. Acceleration is rate of change of velocity, as velocity is speed in a certain direction, when moving in a circle an object's velocity is constantly changing, as its velocity is changing it is accelerating.
Explain why an object cannot keep accelerating?
what your talking about is terminal velocity, which is when the downward force of gravity (Fg)equals the upward force of drag (Fd). This causes the net force on the object to be zero, resulting in an acceleration of zero
What is the rate of change velocity called?
The rate of which something changes its velocity is the acceleration. A common mistake is to think that something moving fast is accelerating, but it's only accelerating if the velocity of that object is changing.
When are you most aware of motion in a moving vehicle when it is moving steadily in a straight line or when it is accelerating?
accelerating
When are you most aware of motion in a moving vehicle - when it is moving steadily in a straight line or when it is accelerating?
accelerating
What is the indication that a moving object is accelerating?
moving
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.
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 a body be accelerating when moving at constant speed?
A body is being accelerated if its speed OR direction are changing.A satellite in a perfectly circular orbit around the earth ... like a TV satellite ... is moving at constant speed. But, technically, since its direction is always changing, to keep it on a circle, it's experiencing constant acceleration.
Does the acceleration of the body always change the speed of the body?
Not always. If a moving body changes direction without changing speed then we still say it has had an acceleration. Tie a weight to a piece of string and swing it around your head at a steady speed. The weight is accelerating towards you all the time. If the string were to break, the weight goes on in a straight line unaccelerated.
