What are the steps to draw a Free-Body Diagram?
- Isolate the object. 2. Sketch the object. 3. Identify forces acting on the object. 4. Draw force vectors. 5. Label forces. 6. Add a coordinate system (if needed).
How do you apply Newton's Second Law to solve a problem?
- Draw a free-body diagram. 2. Resolve forces into components. 3. Apply in each direction. 4. Solve for the unknown.
What is the first step in solving force problems using free-body diagrams?
Isolate the object of interest by focusing on one object at a time.
What should you do after identifying all the forces acting on an object?
Draw force vectors with arrows representing each force, starting from the object.
What is the final step in creating a free-body diagram?
Add x and y axes if needed for analysis to create a coordinate system.
What happens when the net force on an object is zero?
The object's acceleration is zero (it remains at rest or moves with constant velocity).
What is the effect of increasing the net force on an object?
The object's acceleration increases proportionally.
What happens to acceleration if mass increases and force is constant?
Acceleration decreases.
What is the effect of friction on a moving object?
It opposes the motion, causing deceleration.
What happens when tension is applied to a rope connected to an object?
The object experiences a force in the direction of the rope.
In a free-body diagram, what does the length of a force vector represent?
The magnitude of the force.
In a free-body diagram, what does the direction of a force vector represent?
The direction in which the force is acting.
