What is a scalar? Give an example
A quantity with only a magnitude (no direction). Ex: 400 calories
100
The starting point you choose to describe the location, or potion of an object.
What is reference point?

What is a vector? Give an example
A quantity with both a magnitude and a direction. Ex: 5 m/s South

What is the difference between "distance" and "displacement?" Be complete -- I'm looking for the best answer!
Distance is the total amount of ground covered by an object, and is a scalar quantity. Displacement is the object's change in position, from starting point to ending point. It is a vector quantity. Distance usually has a greater magnitude than displacement.

It takes a car 20 seconds to travel 1000 meters. How fast, on average, was the car moving?
Speed = Distance/Time Speed = 1000m/20s Speed = 50 m/s
200
If a plane travels 1000 km in 2hrs from Indianapolis to Orlando, FL, this is its' velocity.
What is 500 km/hr south?
200
Graphs that compare distance and time
What is distance-time graphs?
300
45,000 km Is this quantity a scalar or a vector? EXPLAIN WHY
Scalar, because the quantity only has a magnitude (an amount), and no direction.
300
Length of a path between two points.
what is distance
300
If a motorbike is moving at 30 m/s for 10 seconds, how far does it travel?
Speed = Distance/Time Distance = Speed x Time Distance = 30m/s x 10s = 300 meters
300
The difference between speed and velocity. Use the words distance, time, and direction.
What is speed is distance divided by time, whereas velocity is speed in a given direction.
300
Distance-time can calculate this for an object.
What is average speed?
400
Is Speed a vector or scalar quantity? Why
Scalar

Juana walks 300 meters West, then 200 meters East. What is her total distance traveled? Displacement? Draw a picture.
Distance = 500 m Displacement = 100 m West
400
How long would it take for a dog that runs at 4 m/s to travel 28 meters?
Time = Distance/Speed Time = 28 meters/4m/s Time = 7 seconds
400
Jackie walks 20 meters West, then 20 meters East, and finally 10 meters South. She does this in 20 seconds. What was her speed? Velocity? Show your work.
Speed = 2.5 m/s Velocity = 0.5 m/s South
400
When the slope line on the distance-time graph increase the object is doing this.
What is speeding up?

The park is located 54 meters from your home. You can run as fast as 6 m/s. How long would it take for you to get to the park from your house is you sprinted?
Time = Distance/Speed Time = 54 meters/6m/s Time = 9 seconds
500
Belem rides her bike 10 meters West, 10 meters South, 20 meters West, then 10 meters North. She does this in 10 seconds. What is her speed? What is her velocity? Show your work.
Speed = 5 m/s Velocity = 5 m/s West
