As you jump across a small stream, does a horizontal force keep you moving forward? If so, what is that force? [Note—this question seems to be deliberately designed to trick you! Is there really a horizontal force being applied once you’ve left the ground?]

There is no horizontal force

Explanation:

When you jump across the stream, your motion is the same of the motion of a projectile, which consists of two independent motions:

  • A uniform motion (constant velocity) along the horizontal direction
  • A uniformly accelerated motion (with acceleration equal to the acceleration of gravity) in the vertical direction

We notice that as you are in the air, there is only one force acting on your body: the force of gravity, whose direction is downward, and causes your body to accelerate downward with an acceleration equal to

[tex]g=9.8 m/s^2[/tex]

However, there is no force acting on you in the horizontal direction: therefore, your acceleration in this direction is zero, and so your horizontal velocity is constant (that's why you keep moving forward).
