True/False: Joules are used to measure force.

True/False: A fulcrum is the pivot point of a lever.

The combination of an object's speed and direction is its energy.

True/False: Oars on a boat are examples of second-class levers.

In a first-class lever, what is the relationship between the effort's distance to the fulcrum and the amount of effort force needed to move the load?

If a third-class lever requires more effort, what advantage does it provide?

An object needs to travel a set distance. In order to do more work, what must increase?
