Acceleration can be either a change in speed or a change in
the direction of the motion even if speed doesn't change.
a=dv/dt
What else can I help you with?
Does acceleration refers to increasing speed decreasing speed or changing direction?
Acceleration refers to increasing or decreasing speed. When an object changes its speed, it is said to be accelerating, whether the speed is increasing or decreasing. Changing direction is related to a different aspect of motion called velocity.
Why does acceleration change when speed does not?
Acceleration is the rate of change of speed, so if speed is constant, acceleration is zero. However, if speed is constant but direction is changing (e.g. moving in a circle at constant speed), the velocity is changing, and thus there is still acceleration.
Can an object with constant speed be accelerating?
No, an object with constant speed is not accelerating. Acceleration is the rate of change of velocity, so if the speed of an object is constant, its velocity is not changing and therefore there is no acceleration.
Examples of constant speed but changing acceleration?
A body moving with constant speed in a circular path has acceleration changing at every point.
Why does the acceleration of an object affect the speed?
Acceleration is simply a measurement of how the speed is changing, over time.
How is acceleration related to the change in speed?
A change in speed (and/or direction) is acceleration.
How can you identify how quickly speed is changing?
You can identify how quickly speed is changing by calculating acceleration, which is the rate of change of speed over time. Acceleration can be calculated using the formula: acceleration = (final speed - initial speed) / time. A positive acceleration indicates speeding up, while a negative acceleration indicates slowing down.
If you speed is not changing but your direction is changing are you accelerating?
Yes; acceleration is any change in velocity - speed, or direction.
Velocity and acceleration related?
Acceleration is the rate at which velocity is changing, with the direction of the change.
What is the relationship between acceleration and velocity?
Acceleration is the rate at which an object's velocity changes over time. In other words, acceleration measures how quickly an object's speed or direction is changing. Velocity, on the other hand, is the speed and direction of an object's motion. So, acceleration and velocity are related in that acceleration affects the change in velocity of an object.
Can a body moving at a constant speed have acceleration?
Yes. Acceleration is any change in velocity. Velocity is a vector quantity because it includes both speed and direction. Speed is a scalar quantity and does not include direction. Therefore, if your motion is changing direction, then you have a changing velocity regardless of your speed. And a changing velocity means you have acceleration.
Compare the tension of a train with constant speed and acceleration?
Unless the train is in a curve, you cannot have constant speed and constant acceleration. You either have constant speed and zero acceleration, or you have changing speed and constant acceleration. Please restate the question.
