Usually any learner would get a doubt regarding the force acting on a body.
There are many situations.
1: If a force constantly acts on a body, then it will be accelerated. So its speed would go on increasing if it starts from rest.
2: If a force acts on a uniformly moving body opposite to the direction of motion, then the speed of the body would go on decreasing and it comes to stop. Yet the force is in action, then the body would get accelerated in the other direction.
3: If a force is applied in such a way that it is balanced by an equal and opposite force, then neither acceleration nor retardation is possible. Yet the body could be got moved through some displacement. In such a case we compute only the amount of work done by that applied force.
Examples:
a) Lifting a book against its gravitational weight.
b) Dragging an object on the floor exerting a force which equals to the force of friction between the object and the floor.
Even in the earlier case work is said to be done by the force and that work performed will be available as kinetic energy in the moving system.
But in latter case the energy spent would be available as potential energy in case of lifting and heat energy in case of dragging.
When a force causes an object to move in the direction of force ,WORK occurs because work is said to be done WHEN A FORCE ACTS UPON A BODY AND THE BODY COVERS A DISTANCE IN THE DIRECTION OF APPLIED FORCE.
If the force is continuously applied, the object will experience an acceleration in the direction of the applied force.
If the force is applied once, the object will move at a constant velocity in the direction of the applied force in a vacuum.
If the object is not in a vacuum, it may experience a deceleration and eventually come to rest.
the action of the force that cause the object to move in different action is what we call "unbalanced forces", because it causes the object to move in different speed or direction.
'Acceleration' in that direction results.
gravitational pull/force
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
it moves ----------> there for if you were to push the object it will go <--------
Work is applied to an object and the object is moved over a distance in the same direction of the applied force.
yes, because force is a push or pull, so an example would be that wind (the force) pushed the bike faster toward a building and steered the bike around the building, which causes the bike to change direction. This is an example of velocity too. Velocity is speed in a specific direction.

work.
Work occurs when a force causes an object to move in the direction of the force.
The force is work.
The transfer of energy that causes an object to move in the direction of the force is called work.
Cettripetal Force causes an object to accelerate towards the center. The direction changes as the object moves around the center and is not fixed if the object moves.
Direction will be changed by the force caused acceleration, a=F/m.
Inertia.
It would be Work
gravitational pull/force
A force applied to a moving object in the opposite direction of its motion causes its velocity to decrease.
the frictional forces increase
