- 13. Multiple Choice
Which best explains why we are able to accelerate forward when starting to run?As one leg moves backward, it provides an equal and opposite force for the other foot to move forward.No acceleration takes place. Runners are always at a fixed velocity.The striking foot pushes backward against the ground. The friction with the ground provides an equal and opposite force forward.The runner's upper body quickly leans forward, causing the entire body to begin accelerating forward - 14. Multiple ChoiceWhen a large truck pushes a small car with a given force, the small car is applying an equal and opposite force on the truck.TrueFalse

They hit each other with the same force in opposite directions.
They hit each other with unequal force in opposite directions.
One remains still while the other one moves in the same direction.
