What is the relationship between the magnitudes of the effort and resistance forces and their distances from the fulcrum?
They are directly proportional
What is the trade-off of using a lever?
It reduces the amount of work needed to lift something

It is not mentioned
What is the length of the lever needed to lift the Earth according to Archimedes' famous boast?
A quadrillion light years
What is the purpose of simple machines?
To reduce the amount of energy required for a task
What is the fundamental principle behind the lever?
The ability to reduce the amount of energy required for a task
What are the three main components of a lever?
Effort arm, resistance arm, and fulcrum
What is the relationship between the magnitudes of the forces and their distances from the fulcrum?
The product of the effort force and the length of the effort arm equals the product of the resistance force and the length of the resistance arm
What is the trade-off in using a lever?
The amount of work needed to lift something is reduced
What is the weight of the Earth?
6 x 10^24 kilograms
How long would a lever need to be to lift the Earth using the Moon as a fulcrum?
A quadrillion light years
What is the purpose of simple machines?
To reduce the amount of energy required for a task
What is the fundamental principle behind the lever according to Archimedes?
Using a lever to lift a weight that would otherwise be too heavy.
What is a teeter-totter or seesaw an example of?
A lever, which is one type of simple machine.
What are the three main components of every lever?
The effort arm, the resistance arm, and the fulcrum.
What is the important relationship between the magnitudes of the effort force and resistance force and their distances from the fulcrum?
The lever is balanced when the product of the effort force and the length of the effort arm equals the product of the resistance force and the length of the resistance arm.
What is the basic law of physics that a lever relies on?
Work measured in joules is equal to force applied over a distance.
What trade-off does a lever provide when trying to lift something heavy?
Increase the distance and you can apply less force.
