when distance of an object changes in relation to another object
What is motion?
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
the rate at which velocity changes
What is acceleration?
A train travels 168 km in 4 hours. Find its speed.
What is 42 km/hr?
The graph represents this.
What is increasing speed (positive acceleration)?
the formula for calculating speed
What is:
Speed = Distance/Time
Unbalanced.
This graph is showing a straight line as the velocity increases. The straight line represents this.
What is a constant speed?
Calculate the speed of the train if it travels 60km in 2 hours.
30km/h
The graph represents this.
What is decreasing speed?
the speed and direction of an object's motion
What is velocity?
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.
another word for decreasing speed
What is deceleration?
10 km/h
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?
What does a horizontal line mean on a motion graph?
At rest or stopped
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?
Acceleration refers to one of three types of movement, including:
1. increasing speed
2. ________________________________
3. ________________________________
What is decreasing speed and change in direction?
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
What is happening in a graph where a diagonal line is sloping toward the x-axis?
back to point of origin
the distance an object travels in one unit of time
What is speed?
Force 120N moving left and Force of 80N moving left. What is the net force and direction?
200N left
the formula for calculating acceleration
What is:
Acceleration = Final velocity - Initial velocity/Time
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.
Use the graph to determine Marie's speed from point A to point B.
What is 1 mi/min
