Competency #1
Explain motion using force diagrams and Newton's three laws of motion
Learning Objectives f and g.
- f. Draw force diagrams for stationary or moving objects
- g. Assess the significance (relative size) of each force for a given scenario
Question
Write down your answer to the following question:
A book and a piece of paper (a page from the book) are dropped side by side from a distance of 5 feet above the earth. The book hits the ground first. Draw a force diagram for each object, 0.5 seconds after they are released (neither object has hit the ground yet). Use an arrow to indicate the direction and magnitude of each force. Is the air resistance significant for either or both objects?
