No.
Direction of force and velocity may be different.
Suppose a thread is tied with a toy car. We pull that thread in about 45 degrees with horizontal. But car moves on land.
So,
In such casses work done can be calculated by formula,
W = F.s cos theta
No. Force is not required in order for an object to move.
If an object is found to be moving, then with no forces acting on it, it continues moving with constant velocity.
However, force is required to change an object's velocity. In other words, you'll need force if you want to start something moving, or stop something from moving.
So, in a way, force is required for things to move because something has to get it moving to begin with. But once something is moving, it does not need force in order to continue moving.
No force is needed to keep an object moving. An object with no forces on it
keeps moving at a constant speed in a straight line.
If there is any force acting on it to make it slow down, then you need just enough
force to cancel the first one, in order to keep it moving.
The net force is simply the combination of all forces on an object; there could be three forces pushing an object, so the direction in which the object would move depends on the strongest force. So the answer is no, an object doesn't have to move in the direction of its net force.
This question has some degree of ambiguity by the term "unbalanced force"So I will re-interpret that as "net force"
Net force could be thought as the addition (and subtraction) of all the forces acting on that object,
or if you want to think of it like the final direction after all the forces interact with the same object.
In this case the answer is yes, but it is only "instantaneous" meaning that is only certain that the object is traveling at that direction only for a moment in time. From our experience, we know that forces could change at any given time or distance either because acceleration or mass change ( like meteor approximating Earth, its acceleration increases as it falls, and its mass burns (decreases) as it falls).
accel. and mass multiplied together define Force. So if either of them change as a function of time or distance, then the net force changes and thus, the direction at which the object travels also changes. Technically, the answer is still yes, but to clarify it better take intoconsiderationcircular motion.
when an object is spinning around any given axis (circle) or set of axis (ellipse, centroid), its net force changes at every single point, so one moment the force could be going to the right, the next it could be going down. So at position A, the net force is A, and the direction is A, but at position B, it will have net force
B, and thus it will no longer have direction A. Note that the answer is still YES! an object will always move in the direction of the "net force"
When an object is moved toward a force by a force it is the result of magnetism. The force of the magnet draws an iron object toward itself.
That depends on the mass of the object!
F=ma where Force F acceleration a and mass m in an ideal environment with no friction.
Yes, If you were rolling a ball and it hit a wall then it would bounce back and roll the opposite way.

The force of friction ALWAYS acts in the direction exactly opposite to the directionin which the object is moving.If the friction force acted in the same direction as the object's motion, then youwould want to have as much friction as possible, because that would help youmove the object with less fuel.
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.
Friction will always act in the direction opposite of the relativistic motion of two objects. If object A is moving to the right on object B, then object A will experience the friction to the left. However, object B will be moving to the left on object A and will therefore experience the friction acting towards the right.
Yes. If there is an unbalanced force on an object, the object will always accelerate in the direction of the force.
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.
The centripetal force which always acts perpendicular to the motion of the object
If an object is increasing in speed, the acceleration is positive and the force is in the direction of travel. If the object is slowing down, the acceleration is negative and the force is acting against the direction of movement.
A single force on an object, or a net force ... the sum of all forces on it when the sumis not zero ... always changes the object's velocity ... speed, or direction, or both.
A single force on an object, or a net force ... the sum of all forces on it when the sumis not zero ... always changes the object's velocity ... speed, or direction, or both.
Friction always acts in a direction opposing the motion of an object.
An object will accelerate in the direction of net force
Centripetal Force, it always points to the center of the circle.
The "force" of friction is always exactly opposite the direction of motion.
Friction acts in the opposite direction of the object's motion
kinetic Frictional force always opposes the moving body... therefore its always is in the opposite direction
