1. Using a crowbar to lift a heavy object off the ground. The lever transfers the force applied at one end to lift the object at the other end, making it easier to lift.
2. Using a seesaw to balance two people of different weights. The lever transfers the force applied by the heavier person towards the lighter person, balancing the seesaw.
3. Using a nutcracker to crack open a nut. The lever transfers the force applied at one end to break the shell of the nut at the other end, making it easier to crack open.
4. Using a pair of scissors to cut paper. The lever transfers the force applied by squeezing the handles to the blades, making it easier to cut through the paper.
5. Using a wheelbarrow to lift and transport heavy loads. The lever transfers the force applied by pushing down on the handles to lift the load at the front, making it easier to move.
Mechanical Energy Transfer with Levers
Levers change the direction of a mechanical force to make the force needed for the job less (easier)
