Jill wants to investigate how objects move and see if she can make correct predictions. She knows she will have to observe the object's motion. She wants to see how high different bouncy balls will go on the same surface.

If Jill performs the fourth trial, what prediction can be made about "Ball 3"?

What would be the most appropriate tool to measure the weight or mass of the marbles in the data table below?

Grant wants to investigate how objects move and see if he can make correct predictions. He knows he will have to observe the object's motion. He wants to see if a soccer ball will travel further on artificial turf or real grass.

What will Grant need to measure to determine which surface the soccer ball travels furthest on?

How will the motion of the individual change due to the unbalanced forces?
