| Left Force (Blue) | Right Force (Red) | Net Force | Direction | Result (Crate) | | :--- | :--- | :--- | :--- | :--- | | 0 N | 0 N | 0 N | None | No movement | | 100 N | 100 N | 0 N | None | No movement (or constant speed if moving) | | 100 N | 200 N | 100 N | Right | Accelerates Right | | 300 N | 100 N | 200 N | Left | Accelerates Left | | 200 N | 0 N | 200 N | Left | Accelerates Left | | 50 N | 150 N | 100 N | Right | Accelerates Right |

When forces are equal in size but opposite in direction, the net force is zero, and the object's motion does not change. 2. Unbalanced Forces | Left Force (Blue) | Right Force (Red)

In this simulation, you will see a grey crate on a skateboard. Arrows represent forces (measured in Newtons, N). You click and drag on the arrows to change the size of the force applied by the "blue team" (left) and the "red team" (right). Arrows represent forces (measured in Newtons, N)

If you are searching for a you are likely a student trying to check your work, a teacher preparing a lesson plan, or a homeschool parent looking for grading support. In the simulation, you can place figures of

In the simulation, you can place figures of different sizes on the left and right sides of a cart.

Place one medium figure (100N) on the left and one medium figure (100N) on the right. Net Force: 0 Newtons . Motion: The cart remains stationary (no movement).
