Having a net force always leads to an acceleration due to Newton's famous law; F = m * a. An acceleration is a change of velocity therefore a net force will always change the velocity of an object.

What always changes the velocity of a object?
The velocity of object always changes with wanted or unwanted outer forces.
What is an object that always changes the velocity of the object?
Wanted and unwanted outer forces will always change the velocity of an object.
What Always change the velocity of an object?
Force changes the velocity of an object by acceleration, a=F/m.
What happens when you have unbalanced forces acting on an object?
Then the object accelerates; its velocity changes.Then the object accelerates; its velocity changes.Then the object accelerates; its velocity changes.Then the object accelerates; its velocity changes.
What is it called when an object changes velocity?
That's simply called a change in velocity. On the other hand, the rate of change in velocity - how quickly velocity changes - is called acceleration.
Why the speed of an object is constant while the velocity is not?
This is not always the case. But if an object moves in a circle, at constant speed, its velocity will change. Velocity is a vector - consisting of the magnitude (the speed), and a direction. So by definition, if the direction changes, the velocity changes - you have a different vector.
What is the relationship between velocity and unbalanced forces?
An unbalanced group of forces acting on an object always changes the object's velocity.
The rate at which an object changes position is called what?
Velocity - has speed and direction
What happens when velocity changes?
When velocity changes, that means that the object either moves faster, or moves slower, or moves in a different direction. Any of these changes is called "acceleration".
What is the rate at which the velocity of an object changes over time?
Acceleration is the rate at which the velocity of an object changes over time.
When an object is accelerating if its?
An object accelerates if its velocity changes. More precisely, "acceleration" is the rate of change of velocity (how quickly velocity changes), or in symbols, dv/dt.
What is it when velocity changes?
When velocity changes, that means that the object either moves faster, or moves slower, or moves in a different direction. Any of these changes is called "acceleration". A force is necessary to cause it.
An object is accelerating if its time or direction changes?
An object is accelerating if its speed or direction changes with time. Since speed and direction are the components of velocity, an object is accelerating if its velocity changes with time.
What is the change in velocity of the motion of an object i?
The change in velocity is just the change in velocity. The RATE of change of velocity - how quickly velocity changes - is usually called "acceleration".
Is the rate at which an object changes velocity?
No, velocity is the instantaneous speed of an object, the rate of change would be the acceleration of the object.
Does acceleration always mean that things speed up?
No, acceleration is change in velocity. (And velocity is speed in a certain direction.) If an object slows down, then it is changing velocity and thus accelerating. (In this case, the acceleration is negative.) If an object changes direction, then it's velocity changes, so this is also acceleration. (This is centripetal acceleration.)
Does acceleration always mean that an object is speeding up?
No. As used in physics, the word "acceleration" means that THE VELOCITY CHANGES. More precisely, it refers to how quickly the velocity changes, in symbols, dv/dt.
What indicates the acceleration of an object?
Velocity. A change in VELOCITY will always indicate the acceleration of an object.
Can an object with 0 velocity have 0 acceleration?
Velocity is defined as the rate at which an object changes its velocity; therefore if there is zero velocity then acceleration is neutral as well.
What is a vector quantity that includes the speed and direction of an object?
That is called "velocity".That is called "velocity".That is called "velocity".That is called "velocity".
Is Velocity the change of speed or of direction of an object?
Nope. 'Velocity' IS the speed and direction of motion. If either one changes,that's called 'acceleration'.
Can accelerated body have zero velocity?
An object can only accelerate if its velocity changes.
How is motion describe when the velocity of an object changes by the same amount each second?
That is called constant acceleration.
Why is an object traveling in a circular motion accelerating?
acceleration is change in velocity.. and velocity constantly changes in circular motion, as the direction constantly changes. This constant change in velocity causes the object to accelerate.
