If Mary is pushing the stack of books with a force of 40N and Carla is pushing the same stack of books in the opposite direction with a force of 20N, what is the Net force and who will the books fall towards?
20N toward Carla
100
the rate at which velocity changes
What is acceleration?
100
A train travels 168 km in 4 hours. Find its speed.
What is 42 km/hr?
100
The graph represents this.
What is increasing speed (positive acceleration)?
200
the formula for calculating speed
What is:
Speed = Distance/Time
200
If an object is being pulled with 25N and pushed in the opposite direction with 50N, is the force balanced or unbalanced?
Unbalanced.
200
This graph is showing a straight line as the velocity increases. The straight line represents this.
What is a constant speed?
200
Calculate the speed of the train if it travels 60km in 2 hours.
30km/h
200
The graph represents this.
What is decreasing speed?
300
the speed and direction of an object's motion
What is velocity?
300
If an object is traveling at a constant speed and direction of 55 miles per hour, are the forces acting on the object balanced or unbalanced?
Balanced.
300
another word for decreasing speed
What is deceleration?
300
What is the speed of the car if it travels 250km in 25 hours?
10 km/h
300
Look at the graph showing a car trip. Choose the part of the trip in which the car was traveling at the slowest rate.
What is part iv?
400
What does a horizontal line mean on a motion graph?
At rest or stopped
400
If a force is pushing and object 50N North and another force pushing South with the same force, that is the Net force on the object?
0N
400
Acceleration refers to one of three types of movement, including:
1. increasing speed
2. ________________________________

What is decreasing speed and change in direction?
400
What is the average speed of the car if it traveled 120 miles the first day and 200 miles the second day and the total time on the road was 10 hours?
32 mph
400
What is happening in a graph where a diagonal line is sloping toward the x-axis?
back to point of origin
500
the distance an object travels in one unit of time
What is speed?
500
Force 120N moving left and Force of 80N moving left. What is the net force and direction?
200N left
500
the formula for calculating acceleration
What is:
Acceleration = Final velocity - Initial velocity/Time
500
If a car had an average speed of 50 miles per hour for its entire trip to Orlando Florida and they traveled for 2 hours what was the distance they traveled?
100 miles.
