Why can a magnet can exert a force over distance?
A magnet can exert a force over a distance because of its magnetic field. The field extends around the magnet and interacts with other magnetic materials or objects at a distance, causing them to be attracted or repelled. This force is the result of the alignment of magnetic moments within the material.
What is it when you exert force on an object that causes the object to move?
When you exert force on an object that causes it to move, it is called mechanical work. Work is defined as the product of the force applied to an object and the distance over which the force is applied in the direction of the force.
Do objects have to be touching each other to exert electrical force?
No, objects do not have to be touching each other to exert electrical force. The force between charged objects can be exerted through electric fields, which can act over a distance. This force diminishes with distance according to Coulomb's Law.
If you exert an input force over a greater distance than the distance exerted by the output force for an ideal machine compare the size of the input and output forces.?
In an ideal machine, if you exert an input force over a greater distance than the output force, the input force will be smaller than the output force. This is because work input is equal to work output in an ideal machine, and work is calculated as force times distance. Therefore, if the input force acts over a greater distance, the output force must be larger to balance the work done.
If a mechanical advantage of a simple machine is increased how does the distance of the input force compare to the distance of the output force?
If the mechanical advantage of a simple machine is increased, the distance the input force must be applied decreases in relation to the output force. This means that you can exert less input force over a longer distance to achieve a greater output force over a shorter distance.
When you use a ramp what happens to the distance over which you exert force?
The distance is longer than the lift or the drop, but the force you need is less than the weight of the load.
Explain how machines make work easier if they do not decrease the amount of work you need to do?
A machine makes work easier by changing the amount of force you exert, the distance over which you exert your force, or the direction in which you exert your force.
Why can a magnet can exert a force over distance?
A magnet can exert a force over a distance because of its magnetic field. The field extends around the magnet and interacts with other magnetic materials or objects at a distance, causing them to be attracted or repelled. This force is the result of the alignment of magnetic moments within the material.
How is the wheel and axle useful?
It lightens the amount of force you have to exert to travel over a distance.
Does a lever allow a person to exert a larger force over a shorter distance?
yes
How do machines make work easier?
A machine makes work easier by changing at least one of three factors. A machine may change the amount of force you exert, the distance over which you exert your force, or direction in which you exert your force.

Happens when force moves an object over a distance?
speed
Who is greater the applied force or the force exerted by the machine?
That depends on whether the machine is designed to multiply force or distance. A machine designed to multiply distance will exert less force than was applied, and a machine designed to multiply force will exert the greater force over a shorter distance than force was applied to it. As for work, output work is always less than input work because some energy is lost in overcoming friction.
