Weight and Weightlessness

If an elevator  is going up with acceleration, the apparent weight of a body is

• you feel lighter 
• you don’t feel your weight
• you feel heavier 
•  you feel your true weight

if the elavotar accelerate up wards the net force 

• Fn - Fg
• Fn + Fg
• Fn x Fg
• Fn - Ff

if the elevator decelerate up wawards the acceleration 

• Zero
• positive 
• negatize 
• non of the above

if the cable   of the elevator breaks  

• acceleration is same as gravitational acceleration.
• acceleration is greater than  gravitational acceleration.
• acceleration is smaller than gravitational acceleration.
• no acceleration
