Mechanisms change the direction of motion to make tasks easier.(Pulleys) Machines do many different tasks, such as tasks that are too difficult, time consuming or too dangerous for humans to do.
Machines are composed of one or more mechanisms. A mechanism changes one form of motion to another form of movement.
It is easier to push down than to lift a heavy weight because of gravity. Changing the direction of the force makes it easier to get the job done.(Levers) Mechanisms also change the value of forces. The value of power increase, it allows us to use a small force to lift a heavy load to.
The movement we apply is called the input motion. Process A mechanism changes the motion and delivers a different kind of movement, the movement is called output.
We can use different levers to make our lives comfortable. Levers are divided into three different classified classes depending on how the fulcrum, load and effort is arranged.
A lever is a rigid rod that turns around a point called a fulcrum. It is used to change the direction of a force, to transmit a force over a distance, and to increase the value of a force. The weight that needs to be lifted is called the load. The force that has to be applied to lift the load is called the effort.
There are 3 important characteristics in a lever. EffortFalcrumLoad

Mechanisms change the direction of motion to make tasks easier? (True/False) Machines are composed of one mechanism? (True/False) A mechanism changes one form of motion to another motion? (True/False) Why is it easier to push down than to lift a heavy object?
Changing the direction of force makes it easier to get the job done? (True/False) Explain what is the difference between input motion and output motion. List 5 example of machines Levers are divided into three categories which are known as: Draw and label the 3 classes of levers and list one examples for each lever.
Mechanisms change the direction of motion to make tasks easier? (True/False) Machines are composed of one mechanism? (True/False) A mechanism changes one form of motion to another motion? (True/False) Why is it easier to push down than to lift a heavy object? Because you use the same motion as gravity
Changing the direction of force makes it easier to get the job done? (True/False) Explain what is the difference between input motion and output motion. The movement we apply is called the input motion. A mechanism changes the motion and delivers a different kind of movement, the movement is called output.
