1. Did the coin, notebook, and book move when you slightly lift the table (or plank)
at an angle of approximately 15 degrees? Why?
2. What do you think caused them to stay in their position?
3. When you tilt the table at approximately an angle of 45 degrees, did the objects
move? Note down any differences in the way the objects move when the table
was tilted at this angle.
4. What do you think made the objects move? Discuss your answer.

Answer:
1. The coin, notebook and book did not move when the table was tilled slighty (15 degrees from the horizontan There was a force that opposed the motion and kept them in place.
2. Static friction between each of the objects and the surface of the table caused them to stay in their position.
3. The coin, notebook, and book started to move and side along the table when the table was tilted at 45 degrees trom the horizontal It appeared that the coin moved the fastest followed by the notebook and the book.
4. The coin, notebook, and the book moves Decause the static friction keeping them in place has been overcome by another force which in this case is gravity.
