A seesaw is a class one lever.
a seesaw is a lever that is balenced on a fulcrum
first class levers have fulcrum at center and load and effort at extremes, examples are seesaw and scissor.
They are all simple machines, all have a fulcrum, all are levers, all are human powered.
A first-class lever is a simple machine where the fulcrum is positioned between the effort force and the load. This lever system allows for changes in the direction and magnitude of the force applied. Examples include a seesaw or a crowbar.
Some examples of levers that require pushing include: a seesaw, a crowbar, and a hand-held bottle opener.
Examples of first-class levers include a seesaw, scissors, and a crowbar. In these levers, the fulcrum is located between the effort (force) and the load (resistance).
A seesaw is a lever balanced on a fulcrum.
Lever belongs to the category of simple machines. They are three types of levers 1. First class levers 2. Second class levers 3. Third class levers In the first class levers fulcrum is in between applied force and load. common examples are Crowbar , Pair of scissors , SeeSaw , Skull and neck in our body .
