Quiz zum Vortrag
Which of the following statements best explains our ability to accelerate forward when we start running?
- The striking foot pushes back against the ground. The ground friction provides an opposite and equal force forward.
- There is no acceleration. As a runner, I have a fixed velocity.
- The foot not touching the ground propels the entire body as it swings forwards.
- The upper body of the runner quickly leans forwards, which causes the entire body to begin accelerating forward.
- As one leg moves backward, it provides an opposite and equal force for the other foot to move forward.
A horse pulls forward on a carriage with a given force. By Newton's third law, the carriage must be pulling on the horse backward with an equal and opposite force. Given this, what explains why the horse and carriage can move forward?
- The horse's feet push back on the ground. By Newton’s third law, the ground exerts a force on the horse forward, which causes the horse and carrier to go forward.
- The horse's feet push back on the ground. By Newton’s first law, the ground exerts a force on the horse forward, which causes the horse and carrier to go forward.
- The horse's feet push back on the ground. By Newton’s second law, the ground exerts a force on the horse forward, which causes the horse and carrier to go forward.
- The carrier is pushing back on the horse, by Newton's thirds law there is a force from the horse applied on the carrier which causes the carrier and the horse to go forward.
- The law of gravitation and Newton’s third law
