Question

In an elevator acceleration is upwards or downwards

Answer 1

Explanation:

The elevator accelerates upward (opposite direction to negative/downward velocity to reduce velocity magnitude). The inertia of the person would prefer to keep moving downward at the constant speed, so the elevator floor and scale must push up on the person to accelerate him upward, slowing him down

Answer 2

Answer: acceleration in the elevator depends on the acceleration of the elevator which depends on whether it's moving downwards or upwards however the net acceleration is upward while moving up and acceleration is down while going down but

While stoping the lift in a particular floor an opposite acceleration is applied opposite to the direction of motion

Also inside the lift the body remains in the previous state of motion due to inertia therefore it always feel an acceleration opposite to the direction of the acceleration of the elevator except when the lift is moving with constant velocity the the body feels an downwards acceleration due to gravity
