Define scalar
A quantity with only magnitude, no direction
100
What is another way of describing "Frame of Motion"
Point of view
100
What is the definition of distance?
The amount of ground covered
100
How far will G travel in 3 hours if she is traveling 5 km/hr?
15 km

A bird is watching a girl run around the football field to warm up. What type of motion does the bird see?
Rotary
200
Define vector
A quantity with magnitude and direction
200
What does inertial reference frame mean?
The point of view that is stationary
200
What is the definition of displacement?
The change in position
200
If Aarti is traveling at 5 m/s, how many seconds will it take her to travel 25 meters?
5 seconds
300
Aarti is sitting a and watching a puppy wag its tail. What type of motion is she watching?
Oscillatory
300
Shivani passes a ball to Chanda at 20 m/s. Is this a scalar or a vector quantity?
Vector
300
Chanda is standing by the road watching a car drive west at a speed of 50 km/hr. A child in the car is watching Chanda. How fast and what direction is Chanda moving from the point of view of the child?
50 km/hr east.
300
If a man walks 1 km south and then 4 km north, what distance did he travel? What was his displacement?
5 km, 3 km north
300
How many minutes will it take Manisha to travel 10 km if she is riding her bicycle at a speed of 30 km/hour?
20 minutes
400
Identify two types of motion involved in passing a football.
Linear - ball moving to your partner
Rotary - ball spinning
400
Why is displacement a vector quantity?
Because direction matters in displacement
400
Aarti and Manisha are running towards each other, both at a speed of 4 m/s. How fast is Manisha going from Aarti's frame of reference?
8 m/s
400
If a man walks 3 km south and 4 km west, what distance did he travel? What was his displacement?
7 km, 5 km southwest
400
It takes Shivani 2 hours to walk 3 km west and 4 km north. What is her speed?
3.5 km/hour
500
Identify all three types of motion (linear, oscillatory, rotary) when a person is riding a bicycle.
Linear - the bike's motion down the road
Circular - the wheels
Oscillatory - knees moving up and down
500
G is running twice as fast as Seema to the right. Draw arrows to represent their movement.
----> Seema, --------> G (arrow is 2x as long)
500
A bird is flying north at a speed of 20 m/s and looks down at Shivani who is also running north at 5 m/s. What is Shivani's velocity from the bird's frame of reference?
15 m/s south
500
Explain why a man who travels in a circle has a velocity of 0 m/s
His displacement is zero
