Lesson 1416 of 1524
Motion Along a Straight Line
Displacement is the change in position of an object.
Practice this chapterDisplacement is the change in position of an object. Distance traveled is the total length of the path traveled between two positions
Kinematics is the description of motion without considering its causes. The SI unit for displacement is the meter.
kinematics — the description of motion through properties such as position, time, velocity, and acceleration. distance traveled — the total length of the path traveled between two positions. position — the location of an object at a particular time. displacement — the change in position of an object.
Worked example
What does “kinematics” mean in Motion Along a Straight Line?
- 1Use the wording this chapter gives for kinematics.
- 2The book says: the description of motion through properties such as position, time, velocity, and acceleration.
- 3Do not use the meaning of distance traveled. That term means the total length of the path traveled between two positions.
Result: the description of motion through properties such as position, time, velocity, and acceleration
Why. That is the meaning this chapter gives for kinematics.
Do not swap kinematics and distance traveled. kinematics means the description of motion through properties such as position, time, velocity, and acceleration. distance traveled means the total length of the path traveled between two positions.
