In a free body diagram, what forces should be included?
All forces acting on the object, including applied forces, gravity, normal force, friction, and tension.
What is the difference between true weight and apparent weight?
True weight: The force of gravity on an object (mg). Apparent weight: The force an object experiences due to contact forces, which can differ from true weight when there is acceleration.
What are the steps for solving F=ma problems?
- Draw a Free-Body Diagram (FBD). 2. Identify Forces. 3. Determine Direction (+/-). 4. Calculate Magnitudes. 5. Apply F = ma. 6. Check Units. 7. Break It Down.
What are the steps for solving angular tension problems?
- Draw a clear free-body diagram (FBD). 2. Identify all tension forces. 3. Determine the direction of tension (x and y components). 4. Calculate magnitudes using trigonometry and Newton's laws. 5. Solve for unknowns.
What are the steps for solving apparent weight problems?
- Draw a free-body diagram (FBD). 2. Identify Gravity (weight) and normal force. 3. Determine direction (weight is always down, normal force is perpendicular to the surface). 4. Calculate magnitudes using Newton's laws. 5. Solve for unknowns.
