What is negative acceleration?
Negative Acceleration:Negative Acceleration refers to an object whose speed decreases as it moves away from its original starting position.Actually, that's not entirely correct. Acceleration is a vector quantity and, therefore, depends on direction. If an object is moving in a straight line, in the negative direction, its acceleration is positive if its speed decreases with time and negative if its speed increases with time.Think of it this way: if the acceleration vector is pointed in the same direction as the way an object is moving, the object speeds up. If the acceleration vector is pointed opposite the direction of motion, it slows down.
What happens when a moving object speeds up slows down or changes directions is it acelleration?
what happens when a moving object speeds up,slows down,or changes direction?
What are the changes produced by force?
Force can produce several changes. It can change the shape or position of an object by causing it to move or deform. It can also change the speed or direction of an object's motion. Additionally, force can produce changes in the motion of fluids, such as causing them to flow or change direction.
Which gravity speeds up a moving object?
Gravity will speed up a force if gravity acts in the same direction as the object is already moving - for example, if the object is already moving downward - and if counterforces (such as air resistance) don't interfere too much.
What object does not speed up or slow down?
"Speeding up" or "slowing down" are terms which describe an acceleration of an object. Newton's second law of motion (F = ma) defines quantitatively the relationship between force and accelerations. Thus an object that experiences no force also experiences no acceleration and does not slow down or speed up. However, consider a particle moving in a circle with constant speed v. The particle is neither speeding up nor slowing down, but it DOES experience a force and thus an acceleration (there must be a force which keeps the particle moving in a circle instead of flying off in one direction). This force, however, is always pointing perpendicular to the direction that the particle is moving. So in general, an object that neither speeds up nor slows down is one which experiences no force in the direction that it is moving.

What is true when the velocity and the acceleration of an object are in the same direction?
In that case, the object speeds up.
What happens when a moving object speeds up slows down or changes directions is it acelleration?
what happens when a moving object speeds up,slows down,or changes direction?
What occurs any time an object speeds up or slows down or changes direction?
Acceleration. Acceleration is change in velocity. Velocity is its speed and direction. So when one of these things changes, it is undergoing acceleration. Acceleration can be the object speeding up, slowing down, turning right, turning left, etc. Deceleration is lowering the rate of change. You are experiencing no change if you are moving in a straight line at a constant speed.
A force can cause an object to change its speed and or direction?
A force can cause an object to change its speed or direction. A force causes acceleration, as given by Newton's equation F=ma, where f is force, m is mass, and a is acceleration. Acceleration occurs when something either changes direction, like a tether ball is accelerating when it goes around the pole, or when the objects speeds up or slows down.Forces give energy to the object it is acting on.The more mass an object has, the harder it is to move, stop, or change the speed or direction of the object.An object will not start moving unless a force acts on it.An object will not stop moving unless a force acts on it.An object will not change speed unless a force acts on it.An object will not change direction unless a force acts on it.unbalanced

What does a change in an object's motion mean?
It means at least one of these things happens: -- the object speeds up -- the object slows down -- the object keeps moving at the same speed, but turns to a different direction
What is the rate of change of velocity which occurs if an object speeds up changes direction or slows down?
Any change in velocity, whether to speed up, slow down, or just change direction, results from acceleration. Acceleration is an expression of the rate of change of velocity.
When the balanced forces act on an object the object speeds up starts to move slows down stops or changes direction is this acceleration?
Any time speed or direction changes, that's acceleration. There's no way a balanced group of forces could do any of this, though. The vector sum of a group of balanced forces is zero, and where net force is zero, there's no acceleration.
If something has a change in motion it has what?
For any object to change its motion, it must be accelerated and experiences acceleration. Note that a change in motion is a change in velocity. The object either speeds up, slows down or changes direction, and one of those or some combination is a velocity change. Only acceleration will change velocity. We need to offer the reminder that velocity is speed with a direction vector attached to it. An object can travel at a constant speed and be changing direction. This is a change in velocity because of the change of direction. And a change in velocity is, as stated, initiated by acceleration.
