Can a machine increase both the force and the distance over which the force is applied?

A machine is any device that makes work easier by changing a force. Machines may increase the strength of the force, increase the distance over which the force is applied, or change the direction in which the force is applied. There are six types of simple machines.

When a machine increases the force acting on an object What happens to the distance the object moves?

Calculate How much work is done when a 50 N force is applied to a 0.30 m screwdriver to lift a paint can lid? When a machine changes the size of the output force, the distance must change. When the output force increases, the distance the object moves must decrease.

Which machine makes work easier by increasing the output force?

A wedge is a simple machine that consists of two inclined planes, giving it a thin end and thick end. … A wedge makes work easier by increasing the force applied to the object, although it applies the force over a shorter distance. This gives the wedge a mechanical advantage greater than 1.

How do simple machines change the direction of force?

Simple machines use a pivot point such as a lever fulcrum or axle bearing to provide a “counteractive” force to combine with the applied force(s) to produce a resultant force, acting in a different direction and/or with a different magnitude to that applied.

Which of the following simple machines does not change the direction of the force?

A single moveable pulley creates a mechanical advantage; however, it does not change the direction of a force. The mechanical advantage of a moveable pulley is equal to the number of ropes that support the moveable pulley.

When a machine increases the size of the force exerted what happens to the distance?

Increasing Force: When the output force is greater than the input force, the mechanical advantage of a machine is greater than 1. Increasing Distance: When a machine increases distance, the output force is less than the input force. Your input may be cut in half, but your input distance is doubled.

When a machine exerts a force over a distance it is doing?

Work is a force exerted over some distance; therefore two forces are involved when a machine is used. The force exerted on a machine is called the input force, so the input work done on a machine is equal to the input force times the distance over which the input force is exerted.

How does the force between two objects change when the distance between them is reduced to half?

According to the law of gravitation, the force of attraction acting between two bodies is given by, Thus, when the distance between the objects is reduced to half the gravitational force increases by four times the original force.

How does the force of attraction between two objects change when the distance between them is reduced to quarter?

Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.

How do machines change force?

There are three ways simple machines make work easier: by increasing the distance through which force is applied, by changing the direction of applied force, or by multiplying force of speed of the energy applied.

What is the relationship between force and distance when using a simple machine?

One of the trade-offs with simple machines is that as the amount of force required to lift a load decreases, there is a proportional increase in the distance that the load must be moved.
