A force will not increase or decrease an acceleration. If the force is constant, it will cause a constant acceleration. It may increase or decrease the speed. The change of velocity - for the same force - is the same, whether the speed is increasing, decreasing, or just changing direction.
Yep. But this is Newton's THIRD law of motion. He actually came up with three laws of motion that we use today.1: An object in motion will remain in motion and an object at rest will remain at rest unless acted upon by another force.2: An object acted upon by a force will accelerate in the direction of that force.3: Forces always act in equal but opposite pairs.-(Basic definitions!)-
An object floats for three reasons. One, it is less dense than the solution it is floating in. Such as a piece of wood. Two, the object contains something that is less dense than what it is floating in. Such as a baloon. Three, the shape of the object is such that it does not have enough weight to displace enough of the solution to envelop the object. Such as with any seagoing vessell.
A force can cause the object to accelerate, change its shape, or change its direction of motion.
There are more than three possible changes. Some of them are:The object is crushed.The object is stretched.The object undergoes a shear distortion.Nothing happens: the object is more resistant than the forces acting on it.
Forces can push or pull an object, change the object's shape or motion, and accelerate an object.
When the force on an object is unbalanced, the object's velocity may change in magnitude, in direction, or both. The object may accelerate in the direction of the unbalanced force, decelerate, or change its direction of motion.

An unbalanced force can only do one thing: accelerate a mass. This may mean making it change direction, speed up or slow down, begin or stop spinning, cause it to deform or change shape, and many other actions.
Force can cause an object to accelerate or decelerate, changing its velocity. Force can deform or break an object if the force exceeds the object's strength. Force can also change the shape of an object or cause it to rotate if the force is applied off-center.
Three ways an object can accelerate is speeding up,slowing down, and changing direction.
The object may accelerate in the direction of the force. The object may deform or change shape if the force is strong enough. The object may experience a change in velocity or direction of motion.
Either one of the following observations tells you that an object is accelerating: -- Three points in the object's path are not in a straight line. -- The distance the object travels in a period of time is not the same as the distance it travels in another period of the same duration.
The three factors are the: material properties (coefficient of thermal expansion), temperature change, and original dimensions of the object.
Three things that can cause a change in acceleration are a change in the net force acting on an object, a change in the object's mass, or a change in the direction of the force acting on the object.
