Ready, Aim, Fire!

Physics with Angry Birds.On Your Mark! Creating Your Design.

By: Amanda Jacobs and Lindsay Wescoe


2/23

Essential Question:What variable/s do you think

would affect a projectiles

accuracy and power?How do you know?


3/23

Catapults arent just used in

games such as Angry Birds,

they have been used forcenturies for a variety of

reasons.

Point to Ponder


4/23

Overview of Angry Birds

game. App for fun and

entertainment. A real

world connection!

*While you are watching, look at howthe projectile is hitting or missing thetarget. Think about what makes thelaunch successful.

The ballista was operated by using tension asthe force like in a crossbow in order to hit

specific targets with accuracy and speed.

The arms were pulled back to create tension

and twist the ropes while the bowstring waspulled by people or winch. It ranged from a

small, portable design to a large, three-tondesign used for large siege warfare.

The Mangonel: The mangonel was a small

catapult that was made of an arm and cup

mounted to a wooden frame.


10/23

The mangonel was

operated by a tightly

wound rope and

needed one personto arm in order to hit

targets from a closer

range.

The Power behind the Mangonel


11/23

The Trebuchet: The trebuchet had a pivoting wooden

arm with a heavy weight at one end and a sling,

containing a missile such as a stone, at the other.


12/23

The trebuchet was

operated by counterpoise,

cranking an arm into

position by men pulling

ropes or a windingmechanism, and locking

the arm as a trigger until

released or a weight was

dropped to release theprojectile in order to cause

large-scale destruction.

Catapults have been

used for many reasons

in Siege Warfare!


14/23

Tension vs. Torsion vs. Traction-Powered Catapults

Tension catapults

were more likely to

shoot farther and

were often portable.

Torsion catapults

would tighten to the

attached rope to

build potential

energy, thus

increasing the force

and kinetic energy

when the rope is

released.

Traction powered

catapults, used

applied force by

people as the

power

source. Traction

catapults werelever-based.

Power, speed and distance of a catapult.

Click on the picture for a short video. Think about the

possible variables that might affect the power of your

catapult.

Step 1: Identify the Problem (identify that they need to hit a 2-D and 3-D

target with power and accuracy)

Step 2: Research the Problem (background knowledge on how they were

designed in the past to be powerful and accurate)

Step 3: Develop Possible Solutions (sketch of their catapult)Step 4: Select the best possible solution (chose their materials to make their

best sketch)

Step 5: Construct a prototype (construct their catapult)

Step 6: Test and Evaluate the Solution (Trail launches against 2 and 3-D

targets)

Step 7: Communicate the Solution (record success of their data on paperand Animoto)

Step 8: Re-design (SCAMPER and modify to hit 2-D, 3-D and behind

obstacles with power and accuracy)

2. As you do your simulations, post

any ideas you have on materials or

how to build your catapults.
