Physics question, ? which of these should a free body diagram of a car being driven along a highway include? a) the horizontal component of force that the tire exerts on the road to accelerate b) the force of the engine in turning the driveshaft of the car c) the velocity vector for the moving car d) the force of gravity on the car

D) The force of gravity on the car

Explanation:

The free-body diagram includes all forces applied to the analysed object. Option D is the only one which includes a force (the force of gravity) applied on the car (our analysed object). In Option A, the force is applied on the road, not the car. In option B, similarly, than before, the force is not applied to the car itself. In option C, there is no force involved.
