What do the time and distance graphs we use represent?
Experiment
Weathering
Breakdown of rocks
Independent variable
Variable that changes because of the scientist
Unbalanced force
Two unequal forces acting on an object with change in motion
Solve for speed(math)
distance divided by time
To move an object to the left which side needs a greater net force?
left
constant variable
stays the same
Balanced forces
Two equal forces acting on an object with no change in motion
solve for force
f=ma
