$400 Question from Motion
A flea is sitting on the back of a dog. The dog walks in front of a person seated in a chair.
The flea thinks the dog is A) Moving B) Not Moving
The person thinks the flea is A) Moving B) Not Moving
Explain why
$400 Answer from Motion
The flea thinks the dog is B) Not Moving
The flea is not changing position relative to the dog
The person thinks the flea is A) Moving
The flea changes position relative to the person as the dog moves past the chair
$500 Question from Motion
How far has this object traveled after 16 seconds?
What is the total distance traveled?What is the displacement?
$500 Answer from Motion
8 meters at 16 seconds
16 meters total distance
0 meters displacement
$100 Question from Graphs
What kind of motion graph is this?
Describe the motion in this graph
$100 Answer from Graphs
Distance/Time graph
Constant speed of 10 meters/second
$200 Question from Graphs
Describe the motion in this graph
$200 Answer from Graphs
Waits 3 second to begin moving, moves at constant speed of 1m/s for 8 seconds, does not move for 5 seconds, moves at constant speed of 3m/s for 2 seconds, pauses for 2 seconds, moves at constant speed of 0.5m/s for 4 seconds, pauses for 4 seconds
$300 Question from GraphsGraph the following situation:
A puppy is lost 80 meters away from his home. It’s home is zero. It begins to head home at 10 m/s for 8 seconds until it makes it back home
$300 Answer from Graphs
$400 Question from Graphs
What does the horizontal line represent in Graph A?
What does the horizontal line represent in Graph B?
A B
$400 Answer from Graphs
Graph A – Staying still (not moving)
Graph B – Constant speed
A B
$500 Question from Graphs
What is the average speed of the marble?
What is the speed at 3 seconds?
$500 Answer from Graphs
Average speed = 10 meters/7 seconds= 1.43 m/s
Speed at 3 seconds = 4 meters/3seconds= 1.33 m/s
$100 Question from Speed & Velocity
What is speed?
How do you calculate speed?
$100 Answer from Speed & Velocity
Speed is the rate of motion; the distance an object travels in a unit of time
Speed (m/s) = Distance (meters)Time (seconds)
$200 Question from Speed & Velocity
Bart ran 5,000 meters from the cops at an average speed of 6 meters/second before he got caught. How long was he running?
$200 Answer from Speed & Velocity
Speed = DistanceTime
Rearrange the formula Time = DistanceSpeed
5, 000 meters = 833.33 seconds 6 m/s
$300 Question from Speed & Velocity
What is the speed of a walking person in m/s if the person travels 1000 m in 20 minutes?
$300 Answer from Speed & Velocity
20 minutes x 60 seconds = 1,200 seconds1 minute
1,000 meters = 0.833 meters/second1,200 seconds
$400 Question from Speed & Velocity
If Justin races his BMW M5 down I-71 for 2,560 meters in 60 seconds, what is his average speed?
$400 Answer from Speed & Velocity
2,560 meters = 42.67 meters/second60 seconds
$500 Question from Speed & Velocity
Which of these 3 lines has the fastest average speed?
$500 Answer from Speed & Velocity
1. 0.5 m/s
2. 0.714 m/s3. 0.625 m/s
$100 Question from Forces
What forces are involved in this situation?
Are the forces balanced or unbalanced?
$100 Answer from Forces
Normal Force (FN)
Gravity (FG)
Balanced Forces
$200 Question from Forces
Are the forces acting upon this skydiver balanced or unbalanced?
Which way is he moving?
Is he speeding up or slowing down?
$200 Answer from Forces
Unbalanced forces.
Accelerating (speeding up) toward the ground.
$300 Question from Forces
Describe the direction the Batmobile is moving and speed at which it is moving.
$300 Answer from Forces
Moving to the right and speeding up
$400 Question from Forces
What forces are acting on this skier?
Draw a diagram showing the force arrows.
$400 Answer from Forces
$500 Question from Forces
Describe the direction the fridge is moving and the speed of the fridge.
$500 Answer from Forces
Moving left and slowing down.
$100 Question from Random
Which graph shows increasing speed?
$100 Answer from Random
They both do!
$200 Question from Random
If it takes Jill 3 seconds to run from the batter’s box to 1st base at an average speed of 6.5 m/s, what is the distance she covers in that time?
$200 Answer from RandomSpeed = Distance rearrange the formula to Speed x Time = Distance
Time
6.5 m/s x 3 s = 19.5 meters
