An accelerating car

You are driving your front-wheel drive car on Comm. Ave. You are stopped at a red light, and when the light turns green you accelerate smoothly so that there is no slipping between your car tires and the road. During the acceleration period, in what direction is the force of friction from the road acting on your front tires? Is it static friction or kinetic friction?

  1. The frictional force is kinetic friction acting in the direction you are traveling.
  2. The frictional force is kinetic friction acting opposite to the direction you are traveling.
  3. The frictional force is static friction acting in the direction you are traveling.
  4. The frictional force is static friction acting opposite to the direction you are traveling.










During the acceleration period, in what direction is the force of friction from the road acting on your rear tires? Is it static friction or kinetic friction?

  1. The frictional force is kinetic friction acting in the direction you are traveling.
  2. The frictional force is kinetic friction acting opposite to the direction you are traveling.
  3. The frictional force is static friction acting in the direction you are traveling.
  4. The frictional force is static friction acting opposite to the direction you are traveling.
