Question

force diagrams
directions: finally! some actual science questions. take about 8 minutes to complete this handout for yourself.
part i: force review
what causes a thing to move?
what do we use to represent forces?
what resists applied forces?
team a and team b are playing tug of war. use arrows to show direction of forces.
team a
team b
part ii: force diagrams
a book is sitting on a desk. draw arrows on the box to describe the forces involved.

Explanation:

1. A force causes a thing to move. Force is a push or pull upon an object resulting from the object's interaction with another object.
2. We use arrows to represent forces. The length of the arrow can indicate the magnitude of the force and the direction of the arrow shows the direction of the force.
3. Friction resists applied forces. It is a force that opposes the relative motion or tendency of relative motion between two surfaces in contact.
4. In a tug - of - war between Team A and Team B, Team A pulls the rope towards themselves with a force (arrow pointing towards Team A) and Team B pulls the rope towards themselves with a force (arrow pointing towards Team B).
5. For a book sitting on a desk, the force of gravity acts downwards (arrow pointing down from the book) and the normal force from the desk acts upwards (arrow pointing up from the book) to balance the gravitational force.

Answer:

1. Force
2. Arrows
3. Friction
4. Draw an arrow from the rope towards Team A and an arrow from the rope towards Team B.
5. Draw a downward - pointing arrow labeled "Gravity" and an upward - pointing arrow labeled "Normal Force" on the box representing the book.
