Same weight.
Same impact?

The load stays at 20 kg. Move it away from the pivot and watch the turning effect change.

Camera: drag sideways or focus the scene and use arrow keys. The lever is held horizontal to isolate the effect of distance; this is a torque demonstration, not a free-motion simulation.

Try it yourself

Can the same weight have four times the turning effect?

At 0.5 m, the torque is 98 N·m. Find the position that makes it four times as large.

The physics behind it

For a downward force perpendicular to the horizontal lever, torque = force × distance. Here, force = 20 kg × 9.8 m/s² = 196 N. At 0.5 m: 98 N·m. At 2 m: 392 N·m. The model neglects the lever’s own weight.
