Lesson 571 of 1524
Kinematics
In symbols, displacement Δ x is defined to be Δ x = x f - x 0 , where x 0 is the initial position and x f is the final position.
Practice this chapterIn symbols, displacement Δ x is defined to be Δ x = x f - x 0 , where x 0 is the initial position and x f is the final position. Displacement is the change in position of an object
The SI unit for displacement is the meter (m). Kinematics is the study of motion without considering its causes.
kinematics — the study of motion without considering its causes. position — the location of an object at a particular time. displacement — the change in position of an object. independent variable — the variable that the dependent variable is measured with respect to; usually plotted along the x -axis.
Worked example
What does “kinematics” mean in Kinematics?
- 1Use the wording this chapter gives for kinematics.
- 2The book says: the study of motion without considering its causes.
- 3Do not use the meaning of position. That term means the location of an object at a particular time.
Result: the study of motion without considering its causes
Why. That is the meaning this chapter gives for kinematics.
Do not swap kinematics and position. kinematics means the study of motion without considering its causes. position means the location of an object at a particular time.
