This is how you can increase friction for the car
Simple machine
Incorrect Placement of Mousetrap on MTCar
To increase the applied force I would do what to the axle?
To increase the applied force I would do this to the lever?
Correct Placement of Mousetrap on MTCar picture
The resistance force is this on the mousetrap car
Too little friction causes this to occur
Too much friction causes this to occur
The applied force is this object on the mousetrap car
To increase the distance the car can travel before coasting I would do this to the axle?
To increase the distance the car can travel before coasting I would do this to the lever?
Use a larger axle OR Smaller wheels
Mousetrap
Attach the string to the lever at a higher spot (lengthen)
Attach the string to the lever at a lower spot (shorten)
Wheels to grip ground too much AND not move/not move far
Wheels to spin out and the car to not move/not move far
Friction between the wheels/ground
Device that increases the applied force (mechanical advantage) at a cost to the distance the applied force is used for.
Use a smaller axle OR Larger wheels
More massive car OR add rubber bands
