1
The Language of Motion Position – Velocity – Acceleration

2
How Fast Is The Truck Moving? Observe the toy truck. What is the approximate speed?? 0 m/s 0.70 m/s 460 m/s 30,000 m/s 220,000 m/s Answer: All of them!

3
Scalar Vs. Vector Measurement Scalar: A quantity with no Direction attached to it, only Magnitude Ex: How many apples would you like to buy? Vector: A quantity with both Direction AND Magnitude. Ex: Dude, stop trying to sell me apples. Just turn around and walk 15 meters away from me. Magnitude: The amount of stuff. Direction: Which way something is going.

4
Distance Vs. Displacement Distance: Scalar Quantity Total distance covered Ex: Odometer on a car. Displacement Vector Quantity Change in position How far away from the starting point. Ex: How far have you travelled from home?

5
Speed Vs. Velocity Speed: Scalar quantity Ex: What is read on your speedometer Instantaneous Velocity Vector Quantity Your Speed and Direction at any given point in time. Average Velocity Vector Quantity (Total Distance / Total Time)

6
Instantaneous vs. Average Velocity Ex: Your instantaneous speed is changing at any given point in time but your average is as follows. Two ways to change Velocity? Change Speed Change Direction

7
Acceleration The change in velocity over the change in time Acceleration is a vector Can be positive or negative

8
Deceleration Try not to use the term decelerating or deceleration Instead us speeding up or slowing down Speeding Up When the Velocity and Acceleration have the same sign Ex: Positive Acceleration in the positive direction Slowing Down When the Velocity and Acceleration have opposite signs Ex: Positive Acceleration in the negative direction
