When a machine shortens the distance over which a force is exerted the size of the force must what?
The size of the force must be greater.
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
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
Which is equal to the product of force exerted by a machine and the distance over which the force is applied?
Well, a 'moment' is: moment = force x perpendicular distance from pivot. 1. If you set it up right, Work (or Energy) = Force X distance. 2. Of course, you could be talking of mechanical advantage, but your English will have to be better for that interpretation (the only clue being "machine").
How much work was done if a force of 15 N is exerted over a distance of 6 m?
Work = force x distance = 15 x 6 = 90 joules
When an inclined plane is used?
a smaller force is exerted over a longer distance.

What is a force exerted over a distance to move an object?
all forces are either a push or a pull. even over a distance. gravity is a pull and its opposing force, upthrust, is a push or for ipc its work

What is a force exerted on a surface divided by the total area over which the force is exerted?
cheeseburger
How do you call the force exerted on a surface divided by the area over which the force is exerted?
Pressure
How much work was done if a force of 15 N is exerted over a distance of 6 m?
Work = force x distance = 15 x 6 = 90 joules
How much work is exerted when a 100N force is applied over 5m?
Work is force times distance - assuming the force is applied in the same direction as the movement.
