Think about when the cart moved and when it didn’t move. Then, think about the forces acting on the cart each time. Using this information, how can you predict when an object will move? Explain using evidence from the simulation.

Will the forces be balanced or unbalanced?
What example (part 1 or part 2) can you use as evidence?
Based on the information provided, we can predict when an object will move by looking at the forces acting on it. If the forces are unbalanced, the object will move in the direction of the greater force. In the simulation, we can see that the cart did not move when the forces were balanced, but it did move when the forces became unbalanced.
For example, in part 2 of the simulation when a force was applied to the right of the cart, the cart started to move to the right because the force to the right was greater than the force to the left. This unbalanced force caused the cart to accelerate in the direction of the applied force.
Therefore, by analyzing the forces acting on an object and determining whether they are balanced or unbalanced, we can accurately predict whether the object will move or not.
