Uniform Motion Terms and Symbols

This course will give you an intro to the terms and symbols that we will be using in the unit on Uniform Motion that are associated with the learning goal below.  

Learning Goal

  1. Students will be able to identify and define symbols and terms associated with uniform motion.

 Scale-

4: Students can use the terms and symbols associated with uniform motion to analyze and explain occurrences of uniform motion.

3: Students can identify the seven symbols associated with uniform motion and define them.

2: With teacher assistance students can identify and define symbols and terms associated with uniform motion.

1: Student has difficulty identifying and defining symbols and terms for uniform motion.

Uniform Motion terms

Terms and definitions

Terms and Definitions

Scalar quantity- A quantity specified only by its magnitude, does not have direction

Vector quantity- A quantity specified by magnitude and direction

Position- Where you are; How far from some zero point and in which direction

Clock reading- When or at what instantaneous time

Time interval- Elapsed time between two clock readings

Distance- Length of path traveled during a time interval

Displacement- How far you are from where you started and in which direction

Average velocity- Average speed and direction over a time interval; the slope of a position vs. time graph

Velocity- How fast something is moving and in which direction

Speed- How fast something is moving; does not take direction into account


Terms and definition matching review

Now that you've seen the terms and definitions, see if you can match them up correctly.

Terms and associated symbols

Terms and symbols

Get familiar with the symbols that represent the terms you have learned about.  

What is the symbol for position?

What is the symbol for clock reading?

What is the symbol for time interval?

How would you write the symbol for distance?

  • The symbol for distance is delta x (a triangle in front of an x).
  • The symbol for distance is delta x (a triangle in front of an x) with an arrow over the x indicating it has direction.

How would you write the symbol for displacement?

  • The symbol for displacement is delta x (a triangle in front of an x).
  • The symbol for displacement is delta x (a triangle in front of an x) with an arrow over the x indicating it has direction.

This is the symbol for average velocity.

This is the symbol for velocity.

This is the symbol for speed.

Terms and symbols overview

Overview

Now that you have been given the terms and symbols associated with uniform motion, keep studying them!  These will help you when discussing uniform motion as well as with making graphs and solving problems later in the unit.  Use this as practice testing material as you will have a quiz over the terms and symbols as well.
