What is friction
the resistance to motion of one object moving relative to another
200
How could you plot the speed of an object
constant speed graph, no speed graph, velocity graph, acceleration graph, constant velocity graph, constant acceleration graph, increasing acceleration graph
200
what is it when there are unequal forces on an object
unbalanced forces
200
acceleration is...
the rate of change in velocity

300
What is distance?
the total length traveled by an object
300
what is it called when the forces are added up
net force
300
formula for average speed
distance/time
300
Newton's 3rd law of motion
all actions need an equal and opposite reaction
300
Find the net force
<30N 15N>
15N
400
what does it mean when the line is straight on a graph?
The object is moving at a constant speed
400
find the next force
3N to the right
400
What is the formula for average speed
Average speed = total distance/total time
400
The 1st law of motion
An object at rest stays at rest and an object in motion stays in motion
