Scissors change the direction of the force applied by the user to cut objects. The force and distance applied by the user remain the same, but the scissors multiply the force at the blades to cut through materials efficiently.
Increasing the distance on a screw does not change the direction of the force, but it requires more force to turn the screw due to the increased mechanical advantage.
Some common examples of vectors include force (direction and magnitude), velocity (speed and direction), displacement (distance and direction), and acceleration (change in velocity with direction).
Simple
Work done is the measure of energy transfer that occurs when a force causes an object to move a certain distance in the direction of the force. It is calculated as the product of the force applied and the distance moved in the direction of the force. Work done can lead to a change in the energy of an object.
A lever in a simple machine is used to amplify force or change the direction of a force by applying a small input force over a longer distance to produce a larger output force over a shorter distance. This is achieved by the lever pivoting around a fixed point called the fulcrum, allowing for mechanical advantage.

This is achieved by the lever pivoting around a fixed point called the fulcrum, allowing for mechanical advantage.
Some things that belong to a lever include a fulcrum (the pivot point), an effort force (the force applied to move the lever), a load force (the resistance being moved), and the lever arm (the distance between the fulcrum and where the forces are applied). Lever examples include a seesaw, crowbar, and a pair of scissors.
Simple machines lets you trade force for distance, or the other way around. Or they change the direction of a force.
Simple machines can increase force by allowing a person to exert their force over a longer distance, reducing the amount of force needed. They can also change the direction of the force applied, allowing for easier movement or lifting of objects in a different direction than the force applied. Overall, simple machines help make work easier by trading off force and distance in a way that benefits the user.
It takes a force to change an object's motion or shape. This force can cause the object to accelerate, decelerate, or change direction. The size and direction of the force determine the extent and nature of the change.
When distance is kept constant but the force changes, the work done will depend on the magnitude and direction of the force applied. If the force increases, more work is done, and if the force decreases, less work is done. The relationship between force and work done is directly proportional when distance is constant.
A simple machine is a device that can change the direction or the magnitude of a force, or the point where it is applied. ... Examples of simple machines are wheels, screw drivers, scissors, knives, nut crackers, and hammers. A wheel and an axle together make a simple machine. visit our website : www. chocolatekidsplayschool.org/
A first-class lever is a simple machine consisting of a rigid rod (lever) that pivots around a fixed point (fulcrum). It is used to increase force, gain speed or distance, or change the direction of a force. Common examples include scissors, seesaws, and crowbars.
