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
How do you accelerate without changing speed?
To accelerate without changing speed, you can change direction. Acceleration is the rate of change of velocity, which includes speed and direction. For example, a car moving at a constant speed on a curved path is constantly changing direction and therefore accelerating, even though its speed remains constant.
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.
Is a jogger moving at a constant speed accelerating?
No, a jogger moving at a constant speed is not accelerating. Acceleration is the rate of change of velocity, so if the jogger's speed remains constant, there is no acceleration.
When a force is applied to an object what are the three ways it can change the object?
When a force is applied to an object, it can change the object by accelerating it (changing its velocity), deforming it (changing its shape), or moving it (changing its position).
What is an example of an accelerating object but moves in a constant speed?
An object moving in a circular path at a constant speed is accelerating because its direction of motion is changing. The object is not speeding up or slowing down but is constantly changing its direction, which results in acceleration towards the center of the circle.
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.
What can you say about the motion of the cart is it in uniform motion or is it accelerating?
If the cart is moving at a constant speed in a straight line, it is in uniform motion. If the cart is changing its speed or direction, it is accelerating.
What is the indication that a moving object is accelerating?
moving
Explain why an object cannot keep accelerating?
An object cannot keep accelerating indefinitely because as it gains speed, the air resistance or friction acting against it increases, eventually balancing out the force propelling it forward. Additionally, as the object's speed approaches the speed of light, it experiences relativistic effects that make it harder to accelerate further.
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
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.
It's an object moves at a constant speed and is excelling it's what travel must be changing?
If an object is moving at a constant speed but is accelerating, then its direction of travel must be changing. This means that even though the object is moving at a consistent rate, its velocity is changing because acceleration is a vector quantity that involves both speed and direction.
