Rocket Science Rumble: Ignite Your Knowledge! Pre Quiz

What is simple machine?

• Machine that carry simple task

• mechanical devices that rely on electricity, or battery.

• mechanical devices that do not rely on electricity, or battery. They are basic devices used to reduce the effort that is used to move something.

• Mechanism that require human intervention at certain period of time

What is a lever?

• A lever is a machine consisting of a mechanical gear and battery

• A lever is a machine consisting of a beam or rigid rod pivoted at a fixed hinge, or fulcrum. A lever is a rigid body capable of rotating on a point on itself.

• A lever is a machine consisting of pneumatic and hydraulic pump

• A lever is a machine consisting of rotating pillar that generate electricity

Which one was NOT a types of lever.

• First Class Lever

• Second Class Lever

• Third Class Lever

• Fourth Class Lever

Which one is the example of second class lever?

• Fishing rod

• Seesaw

• Scissors

• Bottle openers

State TRUE or FALSE: Fishing rod is a first class lever.

• TRUE

• FALSE

What is the function of FULCRUM?

• the point at which the lever rotates

• the force applied to the lever

• the force applied by the lever to move the load

• the parts where the battery being connected

Which one is the advantage of lever?

• Imbalance & Instability

• Limited Range of Motion

• Energy Efficiency

• Friction & Efficiency Loss

What are the relationship between effort, load & fulcrum?

• The bigger the fulcrum, the bigger the effort to move a larger load.

• The higher the fulcrum to the load than to the effort, the bigger the effort to move a larger load.

• The farther the fulcrum to the load than to the effort, the smaller the effort to move a larger load.

• The closer the fulcrum to the load than to the effort, the smaller the effort to move a larger load.

Catapults can be consider as...

• First Class Lever

• First & Third Class Lever

• Second Class Lever

• Third Class Lever
