Balanced and Unbalanced Forces
When the force to applied,the drag force increases and forces acting on the engine is transferred resultant wheels (via rear Drag the brakes are decreases and the acceleration the to the car decelerates. It When forces, dueproduced by theair resistance, act in the oppositeforce is zero. the The resultant forcefriction and car are balanced, decreases. direction. stops accelerating and moves atonconstantare unbalanced and it accelerates. transmission system) the forces a the car speed.
