## Move objects inside elevator.....

1. The problem statement, all variables and given/known data
You are moving a large crate from the back of the freight of the elevator to the front as the elevator is moving to the next floor.In which situation is the force you must apply to move the crate the smallest and in which is it the largest
1> When the elevator is accelerating upwards
2> When the elevator is accelerating downwards.
3> When it is traveling a constant speed.

2. Relevant equations

3. The attempt at a solution
The less force would be needed when the quantity m * ax would be less.
So when the elevator is accelerating downwards the force required would be least
and when the object is accelerating upwards the force required would be maximum .
Is my analogy true ?

 When you're moving the crate in the way the problem describes, what makes it difficult?
 Its really hard for me to analyze this can some one just elaborate the answer for me ??

## Move objects inside elevator.....

Imagine yourself trying to move a large crate. What makes it difficult to move the crate?

You can do this. You must have moved large objects before.
 Its because of static friction and the weight of the object ....

OK, and what does the static friction depend on?
