Free Particle Model Worksheet 1b:
Force Diagrams and Component Forces
In each of the following situations, represent the object with a particle.
Sketch all the forces acting upon the object, making the length of each
vector represent the magnitude of the force. Also use congruency marks to
indicate which vectors are equal in magnitude. Except for #6 & 10, assume
that v = 0.
1. Draw a force diagram for the water-skier. Label the force vectors and use
equality marks on the vectors.
2. Draw a force diagram for the sled and kids. Note that the pull on the sled
is at an angle. Label the force vectors and use equality marks on the
vectors.
3. Draw a force diagram for the table. The dancer is leaning on the table at
an angle while stretching. Label the force vectors and use equality marks
on the vectors.
