What do the arrows on an Activity Diagram represent?

We can draw arrows to show the forces acting on an object. The length of an arrow indicates the size of the force. Its direction indicates the direction of the force.Two forces act on the soccer ball on the right:The Earth's gravity pulls it down.The person's hand pushes it up. This is called an applied force – a force exerted on the object by a person, animal or machine. (If you doubt this force exists, try holding a soccer ball like this for an hour!)The ball is motionless and is not accelerating, so the two forces must be equal and opposite.Another way of showing the forces acting on an object is to draw a free body diagram. A square represents the object, and arrows pointing out from the square represent the forces acting on it.These diagrams make it easy to calculate the net force. In the example, the arrows are equal in length but point in opposite directions. These forces are balanced, so the net force is zero.Question 1SavedLook at the free body diagram for the soccer ball above. Explain how you can tell that the net force on the ball is zero.

The arrow is moving forward. What will happen if the arrow does work on the target? athe arrow will stop moving bthe arrow will move backward cthe target will move the direction that the arrow was moving dthe target will move sideways
