A person with mass m stands upon a scale in an elevator. When the elevator is at rest...
N = mg
N > mg
N < mg
N is based on the speed of the elevator
A person with mass m stands upon a scale in an elevator. When the begins to accelerate upwards...
N = mg
N > mg
N < mg
N is based on the speed of the elevator
A person with mass m stands upon a scale in an elevator. When the begins to accelerate downwards...
N = mg
N > mg
N < mg
N is based on the speed of the elevator
A person with mass m stands upon a scale in an elevator that is travelling up with a constant velocity. When the begins to stop and accelerate downwards...
N = mg
N > mg
N < mg
N is based on the speed of the elevator

A man is parachuting from a high altitude. He is experiencing gravity (Fg) a lifting force going straight up from his parachute (T) that causes him to sink downwards. He is being pushed to the right by a strong wind (Fw).
Which of the following expresses the relationship of forces on the X axis?
Fg = T
Fg - T = ma
Fg - Fw = ma
Fw = ma

A student pushes another student across the floor on a chair. The chair has not been cared for and exerts a strong frictional force that balances the force pushing it across the floor. The student pushes the high friction chair in trial A.
The student then applies WD-40 to the chair and the friction is reduced considerably creating far less friction compared to the first attempt. The student pushing the low friction chair is trial B.
Which of the following graphs expresses the correct relationship.
