No they're all great friends
If the gravitational force is less than the buoyant force, the drag force will act in the opposite direction of the gravitational force.
Force(s) that act in the same direction
Normal force can act on an object
If many forces act in the same direction on an object, then the net force is their sum.
The spring force acts in the opposite direction of the displacement from the equilibrium position.
That depends on the direction of the forces. If the two forces act in the same direction, the resultant force will be doubled and if the two forces act in the oppsite direction, the resultant force will be null or zero.
Forces are vector quantities. This means they have both a magnitude and direction associated with them. If you add vectors going in the opposite directions it is the same as subtracting one from the other. Therefore, the resultant force is the difference between the forces.
When two forces act in the same direction, they will combine to produce a resulting force equal to the sum of the individual forces. This combined force will act in the same direction as the individual forces.
To determine the direction of force in a magnetic field, use the right-hand rule. Point your thumb in the direction of the current, and your fingers will curl in the direction of the magnetic field. The force will act perpendicular to both the current and the magnetic field.
The electric force acts in the opposite direction of the electric field on electrons.
Up
Any part of a force that does not act in the direction of an object's motion does not contribute to the object's speed or change its velocity. This component of force perpendicular to the direction of motion only affects the object's direction or causes it to change its path.
