You stand on a spring scale on the floor of an elevator. The scale shows the highest reading when the elevator
1 answer:
Answer:
2. moves upward with increasing speed.
Explanation:
When an object it going up in an elevator, the object experiences the upward acceleration as well as the acceleration due to gravity. This means that the object feels that they are being pushed down.
Hence, the scale shows highest reading when the elevator moves upward with increasing speed.
The force on the scale would be
Where,
m = Mass of object
g = Acceleration due to gravity = 9.81 m/s²
a = Acceleration of the elevator
