A diagram showing all the forces acting on an object is called? Free-body
What does vector quantity means? A quantity in physics,such as force,that has both magnitude and directions.
What does scalar quantity mean? A physical measurement that does not contain directional information
What does components mean? A vector parallel to the x-axis and another parallel to the y-axis.
What does vector resolution means? The process of breaking a vector into its components
