Lesson 572 of 1524
Two-Dimensional Kinematics
The graphical method of adding vectors A and B involves drawing vectors on a graph and adding them using the head-to-tail method.
Practice this chapterThe graphical method of adding vectors A and B involves drawing vectors on a graph and adding them using the head-to-tail method. The resultant vector R is defined such that A + B = R .
In two dimensions, this path can be represented by a vector with horizontal and vertical components The horizontal and vertical components of a vector are independent of one another.
kinematics — the study of motion without regard to mass or force. head-to-tail method — a method of adding vectors in which the tail of each vector is placed at the head of the previous vector. vector — a quantity that has both magnitude and direction; an arrow used to represent quantities with both magnitude and direction. tail — the start point of a vector; opposite to the head or tip of the arrow.
Worked example
What does “kinematics” mean in Two-Dimensional Kinematics?
- 1Use the wording this chapter gives for kinematics.
- 2The book says: the study of motion without regard to mass or force.
- 3Do not use the meaning of head-to-tail method. That term means a method of adding vectors in which the tail of each vector is placed at the head of the previous vector.
Result: the study of motion without regard to mass or force
Why. That is the meaning this chapter gives for kinematics.
Do not swap kinematics and head-to-tail method. kinematics means the study of motion without regard to mass or force. head-to-tail method means a method of adding vectors in which the tail of each vector is placed at the head of the previous vector.
