What is F=m x a
100
Total space covered from the reference point to the ending point
What is Distance?
100
Equation for acceleration

100
Find the speed of a person walking 60 m in an interval of 10 s
What is 6 m/s?
200
Two objects going in the same direction
=sum of the velocity of both objects
Two objects going in the opposite direction
= subtract smaller velocity from larger velocity
What is Resultant Velocity?
200
Define force
What is the quantitative description of the interaction between two physical bodies, such as an object and its environment.
200
Distance traveled divided by the time interval during which the motion occured. Describes how fast an object moves.
What is Speed?
200
Define friction
What is a force that opposes motion between two surfaces that are in contact?

300
What is the velocity of a train going towards Chicago which traveled a distance of 75 m over a time interval of 7 s?
What is 10.71 m/s
400
Draw a graph of constant velocity
Graph should be labeled with:
Time on bottom with Seconds units
Velocity on Side with m/s
Straight line should be from the origin. No curved lines
400
An unbalanced force necessary to move an object at rest.
What is Net force?
400
Difference between starting and ending point in a single direction
What is Net?
400
A friction that occurs before an object moves. It resists the initiation of sliding motion between two surfaces that are in contact and at rest.
What is Static Friction?
400

What is 33.33333 m/s South?
500
Give an example for balanced and unbalanced forces.
Balanced: car parked on an uphill slope, not moving
Unbalanced: Same car going up a hill or down a hill.
500
Complete path taken no matter the direction
What is Total?
500
Define Kinetic Friction
Opposes the movement of two surfaces that are in contact and sliding over each other
500
