Scalar and Vector Quantities and their Consequences on Force

The video tutorial explains the concept of force as a vector quantity, highlighting the differences between scalar and vector quantities. Scalar quantities have only magnitude, while vector quantities have both magnitude and direction. Examples such as energy and electric current are used to illustrate these concepts. The tutorial also covers how vector quantities can be represented using arrows, with displacement as a key example. Finally, it discusses how to combine forces acting on an object, emphasizing the importance of direction in calculating the resultant force.

How do you calculate the resultant force when multiple forces are acting on an object?

What happens when two forces act in opposite directions?
