instructions: draw a free body diagram for the bolded object in each statement. draw the forces associated with each of the forces acting on the object. (remember friction goes opposite direction of the force applied if not moving or opposite direction of the velocity.) label all of the forces with correct symbols or names.\n1. draw a free body diagram for a cup resting on the counter.\n2. draw a free body diagram for a box being pulled along the floor towards the right.\n3. draw a free body diagram for an acorn falling from a tree.\n4. draw a free body diagram for a piano being pushed by two women towards the left.\n5. draw a free body diagram for a sled sliding to the right and slowly slowing down.
Answer
Explanation:
Step1: Identify forces for cup on counter
The cup has gravitational force ($F_g$) acting down - ward and normal force ($F_N$) acting upward. Since it is at rest, $F_g = F_N$.
Step2: Identify forces for box being pulled right
There is an applied force ($F_{app}$) to the right, frictional force ($F_f$) to the left, gravitational force ($F_g$) downward and normal force ($F_N$) upward.
Step3: Identify forces for falling acorn
The acorn has gravitational force ($F_g$) downward and air - resistance ($F_{air}$) upward. As it is falling, $F_g>F_{air}$.
Step4: Identify forces for piano pushed left
There are two applied forces ($F_{app1}$ and $F_{app2}$) to the left by the women, frictional force ($F_f$) to the right, gravitational force ($F_g$) downward and normal force ($F_N$) upward.
Step5: Identify forces for sled slowing down
There is frictional force ($F_f$) to the left (opposite to the direction of motion), gravitational force ($F_g$) downward and normal force ($F_N$) upward.
Answer:
- Draw a dot to represent the cup. Draw a downward - pointing arrow labeled $F_g$ and an upward - pointing arrow of equal length labeled $F_N$.
- Draw a dot to represent the box. Draw a right - pointing arrow labeled $F_{app}$, a left - pointing arrow labeled $F_f$, a downward - pointing arrow labeled $F_g$ and an upward - pointing arrow labeled $F_N$.
- Draw a dot to represent the acorn. Draw a downward - pointing arrow labeled $F_g$ and a shorter upward - pointing arrow labeled $F_{air}$.
- Draw a dot to represent the piano. Draw two left - pointing arrows labeled $F_{app1}$ and $F_{app2}$, a right - pointing arrow labeled $F_f$, a downward - pointing arrow labeled $F_g$ and an upward - pointing arrow labeled $F_N$.
- Draw a dot to represent the sled. Draw a left - pointing arrow labeled $F_f$, a downward - pointing arrow labeled $F_g$ and an upward - pointing arrow labeled $F_N$.
