Question

question 8
how many forces are acting on earth (and only on earth) in this simulation?
based on that number, are the forces on earth (and only on earth) balanced or unbalanced?
answer:

Explanation:

Step1: Identify forces acting on Earth

In the simulation, the green arrow represents velocity (not a force), the blue arrow represents a force (assuming it's gravitational or another applied force). Since we are only counting forces on Earth, if there is one distinct force vector (the blue one, as velocity is a motion descriptor not a force), there is 1 force.

Step2: Determine if forces are balanced

Forces are balanced when the net force is zero (forces cancel each other out). If there is only 1 force acting on Earth, the net force is equal to that single force. So, the net force is not zero.

Answer:

One force is acting on Earth. The forces on Earth are unbalanced.
