What is the effect of upward acceleration on apparent weight?
Apparent weight increases; you feel heavier (Fn > mg).
What is the effect of downward acceleration on apparent weight?
Apparent weight decreases; you feel lighter (Fn < mg).
What is the effect of no acceleration on apparent weight?
Apparent weight equals true weight (Fn = mg).
What is the effect of free fall on apparent weight?
Apparent weight is zero; you feel weightless (Fn = 0).
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.
What are the differences between true weight and apparent weight?
True weight: The force of gravity on an object (mg). Apparent weight: How heavy an object feels, which changes with acceleration.
Compare upward acceleration, downward acceleration, and no acceleration scenarios in an elevator regarding apparent weight.
Upward acceleration: Fn > mg (feel heavier). Downward acceleration: Fn < mg (feel lighter). No Acceleration: Fn = mg (feel normal).
