Hand Tools
This tool is used to drive nails into wood.
What is a hammer
This simple machine acts as the throwing arm of a catapult
What is a lever
These should always be worn when cutting, drilling, or sanding
What are safety glasses
This process removes rough edges from wood.
What is sanding
This force pulls all projectiles back toward Earth.
What is gravity
This tool is commonly used to cut wood by hand.
What is a tenon saw or a coping saw
This part stores the energy before launch
What is the elastic band
You should do this to long hair before using tools.
What is tie it back
This tool is used to measure lengths accurately
What is a ruler or tape measure
The energy stored in stretched elastic bands is called this.
What is elastic potential energy
This tool helps check if two surfaces meet at a perfect 90° angle.
What is a try square
This is the object launched by the catapult
What is the projectile
This should be checked before using any hand tool
What is whether it is in good condition
When using a handsaw, this is the slot or gap left behind after the cut is made.
What is kerf
Levers are grouped into three classes based on the positions of the fulcrum, effort, and load. Which class has the effort in the middle?
What is a third-class lever
This tool is used to hold workpieces firmly while cutting or drilling.
What is a vice or clamp
When building the catapult, why was it important to measure and mark the timber accurately before cutting?
What is to ensure the pieces fit together correctly (or to improve accuracy and quality of the final product)
You should never point a loaded catapult at this
What is another person
This woodworking principle is often summarised as "measure twice, cut once."
What is accuracy in marking and cutting
What effect does increasing the tension in the elastic bands usually have on how far the projectile travels?
What is increase it
This stationary machine tool is commonly used in the workshop to drill consistent, accurately positioned holes in timber projects.
What is a drill press
Name two factors that could affect how far a catapult launches a projectile.
What are elastic band tension, launch angle, arm length, projectile weight, or construction accuracy? (Any two.)
This safety practice means keeping your work area clean and organised
What is good housekeeping
This material was the primary material used to build your catapult.
What is timber (wood)
This factor can affect how far a projectile travels after launch.
What is launch angle, projectile mass, air resistance, or elastic tension
