Why was the pulley invented?
to gain mechanical advantage. So you dont need to apply as much force to move something. A pulley halves the ammount of force needed, but you need to pull a rope twice as far to move the object the same distance.
To make something move what kind of force do you need?
You need Potential (stored) Energy
Why the output force exerted by a rake must be less than input force?
because you need the force to move it over some distance
Why you need large force to move box without wheels?
due to friction.
Infer why the output force exerted by a rake must be less than the input force?
because you need the force to move it over some distance
Why does a satellite move without the need of force to push it?
Contrary to both intuition AND Aristotle, objects do NOT need a force to continue moving. If an object has no force on it whatsoever, it will continue to move in exactly the way it has before. Satellites continue in circular orbits because there is (pretty much) no friction on them.

Why do you need to use force to move a ball up a ramp when it moves downward by itself?
The force of gravity makes the ball move downward. To move it upward, you need to supply enough force to compensate for this (to stop the downward motion) plus a little extra (to cause the ball to move upward).
How do you break a stone in Pokemon Silver?
You need a Pokemon with the move Rock Smash.

What do you need to move an object from one place to another?
A force (energy)
Why does the input force have to be greater than the force need to lift the bale?
If the force is not greater than the weight of the bale, the bale will not move.
In sims 2 castaway how do you move the boulder in geyser plains?
you need a stone chizzil
When an object move are the force acting on it?
Not necessarily. An object doesn't need a force to move, only to CHANGE its velocity. In empty space, an object can continue moving indefinitely without any force.

How much stone do you need to make a level 7 walls on evony?

How much force it takes to move an elephant?
It depends on how you want to move it. To lift it, the force will need to be greater than the weight of the elephant. To push it, you will need sufficient force to both displace its mass and overcome the friction between the elephant's feet or body and the surface it rests on. I think before I did anything else, I'd entice it with an apple. Dead elephants I leave to Phyicists who have nothing better to do.
