Answer
The vehicle's speed and braking force
Explanation
The stopping distance depends on the energy that must be dissipated by the braking forces, which is influenced by the vehicle's speed and the magnitude of the braking force applied.
Common mistake
Confusing Stopping Distance Factors
Students often think that stopping distance only depends on the speed of the vehicle, ignoring the role of braking force.
Emphasize that stopping distance is influenced by both the energy transferred by braking forces and the initial kinetic energy of the vehicle, which is affected by speed.
