... • A tension force, or an applied force, (when the model car is pushed by hand or a magnet to illustrate that forces do not require physical contact) can overcome inertia. This results in unbalanced forces that cause the model car to move. • As the model moves, it experiences friction. The better the ...

Centripetal Force
... an outward force that exists when an object is in uniform circular motion. However, if the centripetal force that keeps an object in uniform circular motion is suddenly removed, the object does not fly outward away from the center of the circle. It moves along a line tangential to the circle. Thus, ...
