Nothing happens to its motion, and it continues moving
in a straight line at constant speed.
There's no motion on the object.
The direction of the force of friction is such that it opposes the direction of motion that an object would move if there were no frictional force acting on the object.
friction is the reaction to motion
You mean a force I guess. A force acting on an object will make it accelerate or decelerate, and if it is acting at an angle to the existing line of motion will make it change direction.
No. An object that has no net force on it will simply not be accelerating. It can be in motion, but it can not have any change in its velocity.
Nothing gives an object inertia. Inertia is not a force. It is just the tendency of an object to continue in its motion if there is no force acting upon it.
as stated in newtons second law of motion- an object acted upon by an unbalanced force will accelerate in the direction of that force
There would have to be an unbalanced force put an object in motion but once in motion no force is necessary for it to remain in motion
the force is not in the direction of the objects motion.
Motion requires a force acting upon an object. When the object changes so does motion.
downward motion
Yes,unbalaced force may stop or change the direction of motion or accelarate the object.
The motion of an object is determined according to Newton's laws of motion. In particular, acceleration is proportional to force. If you change the force, you change the acceleration. There are many details beyond that, but that is the simple answer to a very broad question. NOTE: Neither the force nor a change in it has any effect on the motion of an object unless the force happens to be acting on the object.
No
Inertia guarantees that an object at rest will remain at rest and an object in motion will remain in that same motion, so long as there is no external force acting on that object. Alternately, there could be force acting on it as long as that force adds up to zero.
Accelerated motion (F=ma)
Motion does not require a force; if no force is acting on a body in motion, its motion will be constant. A force is required to change motion, and any unbalanced force acting on an object can do this.
An object at rest or in motion with no force acting upon it.
