Introduction to Motion
Lesson 1

2. How do we define Quantities of motion?
There are two types of quantities that we use when we talk about motion.
Vector Quantity – has a magnitude and a direction
Example:
Scalar Quantity – has only a magnitude

3. What are the different types of motion?
There are two types of motion we will study:
Uniform Motion
motion in a straight line at a constant speed
Non-Uniform Motion
motion with a change in speed and/or direction

4. Example:

5. Example:

6. Average Speed vs. Instantaneous Speed
The total distance travelled divided by the total time.
Instantaneous Speed
The speed at a particular point in time.
