An accelerating car
You are stopped at a red light in your front-wheel drive car. When the
light turns green you accelerate so that there is no slipping between the
tires and the road. While accelerating, what direction is the friction force
from the road acting on your front tires? Is it static friction or kinetic
friction?
- The force is kinetic friction acting in the travel direction.
- The force is kinetic friction acting opposite to the travel direction.
- The force is static friction acting in the travel direction.
- The force is static friction acting opposite to the travel direction.
While accelerating, what direction is the friction force from the road
acting on your rear tires? Is it static friction or kinetic friction?
- The force is kinetic friction acting in the travel direction.
- The force is kinetic friction acting opposite to the travel direction.
- The force is static friction acting in the travel direction.
- The force is static friction acting opposite to the travel direction.
