Unit 2: KinematicsDescribes the movement of objects using words, diagrams, numbers, graphs, and equations.
What’s the difference between these two measurements?
Measurement 1 To get from MASE to
Kroger, you need to travel about 15 seconds down Jefferson and about 30 seconds down Cleveland.
Measurement 2 To get from MASE to Kroger, I
would travel about ¼ mile west from the parking lot and then at the light, I would travel about ½ mile west again, pass the light at Poplar and there’s Kroger. From MASE, Kroger is a little ½ mile southwest of us.
Scalars have magnitude (or size) ONLYYou only know size but no direction of
movement How much something has changed position is
called distance Examples: temperature, mass, energy, speed
Demonstration: moving a brick The brick moved 5 meters.
Vectors have magnitudeAND direction
A vector is a numerical value (magnitude, or size) in a specific direction
Vectors are drawn as arrows and the direction of the arrow is the direction of the vector while the length of the arrow is the magnitude
Vectors How would you describe the direction of the
block moving in terms of a vector quantity? The brick moved 5 meters to the right
This measurement which includes direction is called a displacement.
Real World Application: FootballA quarterback’s pass is a great example of a
vector because it has direction (usually somewhere downfield) and magnitude (how hard the ball is thrown)
Video from NBC
Real World Application: Billiards/Pool Billiard ball velocity vector would
tell us the speed its going (magnitude) and in what direction
We saw in the video that vectors can be added together to make a parallelogram This helps us figure out what would
happen to one still ball hit by one that is moving at a specific velocity
Billiards players use vectors to predict where both balls will go upon impact
Real World Application: Boats and Planes Imagine a situation where
you're in a boat or a plane, and you need to plot a course. There aren't streets or signs along the way. You will need to plan your navigation on a map. You know where you're starting and where you want to be. The problem is how to get there.

Distance VS. Displacement Distance: how much ground an object has
covered. Distance is a scalar quantity.
Displacement: The object's overall change in
position. Displacement is a vector quantity.
Phabulous Physics: Vectors
Displacement Displacement is an object’s change in position.
Distance is the total length of space traveled by an object.
