velocity
The ratio of the change in position ( displacement ) to change in time. It is the slope of a position time graph.
What is velocity?
This is the difference between distance and displacement.
WHat is distance is total path traveled and displacement is a comparison from initial position to final position?
This is represented by a horizontal line on the position-time graph.
What is the object is not moving?
Another term given for the size of a quantity
The difference between a particle model and a motion diagram.
What is the particle model has dots that replace the images on the motion diagram. Each dot or image represents the passing of equal time intervals?
on a position time graph, the variable plotted on the x
What is the x axis- independent ( time).
Identify which are vectors and which are scalars: speed, velocity, time, distance, and displacement.
Scalar - speed, time, distance
Vector - velocity, displacement
Solve for final displacement from the v = delta d/time
Df = vt + Di
The velocity if an object travels 7500 m in 7200 hours.
What is 10 m/s?
The displacement of a puppy that leaves home (origin) and travels north 5 blocks and then returns along the same path traveling south 3 blocks.
WHat is 2 blocks north?
This is a horizontal line on a pt graph.
What is no movement
The difference between a scalar and a vector quantity.
What is the scalar has only magnitude and the vector has both magnitude and direction?
This allows us to define the direction and determine the magnitude of a vector.
What is a coordinate system?
This is what you do to average velocity to get average speed.
What is take the absolute value?
If a position time graph plotted the motion of two different people or things, this is happening when the lines cross.
What is they are at the same position ( they meet)?
The vector that represents the sum of two or more vectors.
What is the resultant?
Ted leaves his friends house and travels 3.5 km to his friends house. If he travels at a rate of 4 m/s this is how long it will take him to get home.
875 seconds or 14.5 minutes or .24 of an hour
This is the explanation on how it is possible to have zero displacement but have traveled 10 miles.
What is if you travel 5 miles in a direction and then turn and travel back 5 miles. You will be right back where you started?
The slope of a position-time graph.
What is average velocity?

Trying to be on time for class, Johnny moves at 2.4 m/s down a 52 m-long hallway, 1.2 m/s down a much more crowded hallway that is 79 m long, and the last 25 m to his class at 3.4 m/s. This is the amount of time it takes Johnny to get to class.
What is 95 s.
Daily Double
You have 6.0 hours to travel a distance of 140 km by bicycle. If you travel the first half of this journey at an average speed of 21 km/h, this is the amount of time it will take.
What is 3.3 hours
