Acceleration is any change in velocity. Velocity is made up of a magnitude (the speed), and a direction. Velocity can change if the speed increases, if it decreases, or if the direction changes. For example, when a car goes around a curve, you feel the force of the acceleration.
What else can I help you with?
What kind of speed has no acceleration?
A constant speed has no acceleration. When an object is moving at a constant speed, its velocity remains the same over time, and there is no change in acceleration.
Can an object be accelerating if it has constant velocity?
No. The definition of acceleration is the change in an object's velocity over time. Acceleration must then be zero since velocity remains constant.
When the velocity of the body is doubled its acceleration?
When the velocity of a body is doubled, its acceleration remains the same if the direction of motion remains constant. Velocity is the rate of change of position of an object over time, while acceleration is the rate of change of velocity over time. If the velocity is doubled while the direction remains constant, the acceleration does not change.
What is the acceleration of an object if velocity remains constant?
velocity is the first derivative of motion, with acceleration being the second; if an object has a constant velocity, then it's acceleration is 0. This is easy to see from everyday life, when you are in a car, you only feel it jerk when you are accelerating but once you've reached your speed you feel nothing.
Can a particale accelerate if its speed is canstant?
No, a particle cannot accelerate if its speed is constant. Acceleration is the rate of change of velocity, and if the speed (magnitude of velocity) remains constant, then the acceleration is zero.

A constant speed has no acceleration. When an object is moving at a constant speed, its velocity remains the same over time, and there is no change in acceleration.

What is Motion without acceleration?
Motion without acceleration is when an object is moving at a constant speed in a straight line. In this scenario, the object's velocity remains constant and there is no change in its speed or direction.
Can a particale accelerate if its speed is canstant?
No, a particle cannot accelerate if its speed is constant. Acceleration is the rate of change of velocity, and if the speed (magnitude of velocity) remains constant, then the acceleration is zero.
Is it possible that the velocity of a body changes and its acceleration remains constant?
The definition of acceleration is: Any change of velocity, that is, speed or direction of motion. If an object is undergoing constant acceleration, then the definition says that its velocity must be changing.
What is the difference between increasing velocity and uniform velocity?
Increasing velocity means that the body is accelerating and a force is acting on the body to produce the acceleration. Uniform velocity means that there is no acceleration or deceleration and so no force acts on the body. (Note that in practice we cannot achieve perpetual motion because of either the decelerating force of gravity or friction).
Does the horizontal line on the velocity vs time graph indicate a constant and positive acceleration?
Ahorizontal line on a velocity vs time graph does not indicate any acceleration because there is no slope. Speed remains constant.
Is motion with constant velocity an example of motion with constant acceleration?
Well, technically yes, and we even know the magnitude of the constant acceleration.If velocity is constant, that tells you that acceleration is zero, which sounds likea constant to us.
Does the speed of a car moving in a circular path at 15 mph remain constant Or does the acceleration or its velocity remains constant?
The magnitude of the velocity will be constant however the direction will be constantly changing. The acceleration will remain constant towards the centre of the circle
The quantity that can be zero if a body remains in motion for sometime is?
Acceleration. Even if a body remains in motion for some time, its acceleration can be zero if the velocity remains constant.
