What is the difference between mass and weight?
mass is how much matter is in an object, and weight is the gravitational pull on that object
mass and weight are the same
weight affects how much mass is in an object
weight is determined by how many atoms make up an object

A man standing on a scale in an elevator notices that the scale reads 40 newtons greater than his normal weight.
Which type of movement of the elevator could cause this greater-than-normal reading?
accelerating upward
accelerating downward
moving upward at a constant speed
moving downward at a constant speed
A woman standing on a scale in an elevator notices that the scale reads 100 newtons less than her normal weight. Which type of movement of the elevator could cause this greater-than-normal reading?
accelerating upward
accelerating downward
moving upward at a constant speed
moving downward at a constant speed
A man weighing 800 Newtons is standing in an elevator. If the elevator rises with an acceleration of 0.5 meters per second2, the force exerted by the elevator on the man will be
400 N
800 N
1200 N
1000 N
The passenger has a mass of 85 kg. Calculate the force the floor exerts on the passenger.
The passenger has a mass of 85 kg. Calculate the force the floor exerts on the passenger.
The passenger has a mass of 85 kg. Calculate the force the floor exerts on the passenger.
A man standing in an elevator moving with constant speed upwards...
experiences greater Normal force than gravity
has zero net force acting on him
Experiences a net force
has a dashing mustache
A man standing in an elevator that accelerates upwards...
experiences greater Normal force than gravity
has zero net force acting on them
Experiences a net force
would register a lighter weight standing on a scale
A boy stands on a bathroom scale in an elevator. His normal weight is 600 N and the scale reads 720 N,
the elevator's acceleration is
Positive because the apparent weight more than the real weight
Positive because the real weight more than the apparent weight
zero
the information is not enough to know

the elevator's acceleration is
downward
upward
zero
the information is not enough to Answer

A 100 kg man is standing on a bathroom scale in an
elevator. What is the scale reading when the elevator
is moving upward with a constant speed?
0 N
900 N
1000 N
2000 N
When a 45-kg person steps on a scale in an
elevator, the scale reads a steady 480 N. Which of the
following statements must be true?
I. The elevator is accelerating upward at a
constant rate.
II. The elevator is accelerating downward at a
constant rate.
III. The elevator is moving upward at a constant
rate.
IV. The elevator is moving downward at a
constant rate.
V. From the given information, we cannot tell if
the elevator is moving up or down.
I ans II only
II and III only
II and IV only
I and V only
if the elevator moving upward and slowing down,
the real weight equals the apparent weight
the apparent weight is less than the real weight because the acceleration is downward,
the apparent weight greater than the real weight because the acceleration is upward.
if the elevator moving upward and speeding up,
the apparent weight greater than the real weight because the acceleration is upward.
the apparent weight is less than the real weight because the acceleration is downward,
the apparent weight equal the real weight
if the elevator moving downward and speeding up,
the apparent weight greater than the real weight because the acceleration is upward.
the apparent weight is less than the real weight because the acceleration is downward,
the apparent weight equals the real weight
if the elevator moving upward and slowing down,
the apparent weight greater than the real weight because the acceleration is upward.
the apparent weight is less than the real weight because the acceleration is downward,
the apparent weight equals the real weight
when the elevator moving with constant velocity
the apparent weight is less than the real weight
the apparent weight greater than the real weight
the apparent weight equals the real weight
if the elevator at rest.
the apparent weight greater than the real weight because the acceleration is upward.
the apparent weight is less than the real weight because the acceleration is downward,
the apparent weight equals the real weight
A boy stands on a bathroom scale in an elevator. His normal weight is 600 N and the scale reads 720 N,
the net force is
120 N upward
120 N downward
20 N upward
20 N downward
