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.
An accelerating object is one that is changing in either speed or direction. Thus any object that is turning is accelerating while maintaining a constant speed.
No. An object traveling at a constant velocity is not accelerating.
No. Acceleration is any change of velocity.But its speed can be constant.
When an object is not accelerating at all. It has constant velocity.
Since acceleration involves a change in velocity, and object might be accelerating even though its speed is constant.
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.
Not accelerating. It could be stationary or moving at a constant speed.
If the force acting upon an object are balanced then the object must not be accelerating
In a constant state of motion (which may actually be stationary).
No. The definition of 'acceleratiion' is 'any change in velocity'.
A constant force in the direction of the line
When a falling object stops accelerating but is falling at a constant velocity, it is called terminal velocity.
