Acceleration is any change in velocity. It could be a change in speed or direction. Technically, even slowing down is acceleration.
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.
yes an acceleration is a change in speed and when you go around a corner you change your speed.
0. "Constant speed" means it is not accelerating.
Anything that moves in a path that's not straight can do that.
No. Acceleration is the change in velocity(speed) over a period time.=====================================Another contributor bristled:Sorry. Velocity and speed are not two different words for the same thing.Velocity means speed and direction, and acceleration means any change in velocity.If the speed is constant but the direction is changing ... like turning a corner or drivingon a circular track ... then velocity is changing, and there is acceleration.
An object with a constant (vector)velocity is not accelerating. An object with a constand (scalar)speed can actually be accelerating, a car with a constant speed that passes around a corner is changing direction and is subjected to a lateral acceleration.
Yes. The simplest example is an object moving at a constant speed in a circle.
No, you are not accelerating if you are traveling in a constant direction with a constant speed. Acceleration is the rate of change of velocity, so if your velocity remains constant, there is no acceleration.
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.
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.
That is possible, for example, if an object moves around in a circle. In this case, the velocity changes all the time; the speed does not.
yes an acceleration is a change in speed and when you go around a corner you change your speed.
If you have a constant speed, you are not accelerating.
No. 'Acceleration' means a change in speed or direction over time. If the car is moving at a constant speed in a constant direction, then it isn't accelerating.
its not, if ur accelerating ur not staying at a constant speed.
Since acceleration involves a change in velocity, and object might be accelerating even though its speed is constant.
No, an object moving at a constant speed cannot be accelerating. Acceleration is defined as a change in velocity over time, so if the speed is constant, there is no change in velocity and therefore no acceleration.
