Newton's Laws in Angry Birds
Relative Mass
The relative mass of each bird is different. Mass is important because the more mass in this game the more destruction. White bird has the most mass, then yellow, then red, and lastly blue has the least amount of mass.
How Force Effects Angry Birds
Gravity clearly exists in angry birds land. You can see this because all things fall or slide down to the Angry Birds Land Earth. This is demonstrated when you slingshot a bird up into the air, the bird falls back down and accelerates until a point when the bird reaches it's terminal velocity. Another force in angry birds is air resistance. Air resistance is a key component to Angry Birds. Some birds, like the yellow bird, are made for minimum air resistance. If you pull back the slingshot and let go, not only does the yellow bird stay aloft longer, it also can accelerate much faster than the other birds. Certain birds like the black bird for instance, are greatly affected by air resistance. It will not go nearly as for or as straight as other birds do. Finally, every bird breaks through a different type of material easily. The blue bird breaks through glass, the yellow bird breaks through wood, the black bird breaks through stone etc. Because of this effect I know that certain birds have greater mass and density than others. I know this because when the black bird hits stone, there is more mass and thusly more atoms hitting the stone. This is why the stone breaks. When the blue bird hits stone, there is very little mass, and atoms, hitting the stone.This is why the stone does not break.
Speed, Velocity and Acceleration in Angry Birds
The effect the stretch of the slingshot has on the velocity of the angry birds is simple. Where you pull back will determine the bird’s direction. If you pull downwards the bird will go up, and if you pull up the bird will go down. Also, how much you pull back will affect the velocity. If you pull back all the way the bird will be at its maximum speed, and if you pull back a little, the bird’s speed will be at a minimum. The stretch of the slingshot does affect the acceleration of the angry birds because the slingshot is the force. The formula to find out acceleration is force divided by mass, so if the slingshot is the force, it must affect the acceleration. If the force is larger so will be the acceleration. The stretch of the slingshot does affect the force the bird hits the pig fortress. We know this because of Newtown’s third law of motion which is about action reaction. Because the stretch of the slingshot affects force and puts that force in to the angry bird, that angry bird puts the same amount of force on to the pig fortress. This is why if you pull the slingshot farther back, the birds will go through the objects easier because the bird exerts more force on to those objects.
Newton's Laws in Angry Birds
Newton's 1st law - Law of Inertia
The walls of the fortress act as an unbalanced force because when the birds are in motion the wall stops the birds motion.
The slingshot is an unbalanced force because when the birds are at rest the slingshot shoots them into motion.
Newton's 2nd law - Law of Acceleration
The mass of the bird times it's acceleration is equal to the force of the slingshot.
When the wall gets moved out of its place it's mass times it's acceleration equals the force of the bird.
Newton's 3rd law - Law of Action Reaction
When the bird collides with a wall the wall also collides with the bird, that is why the birds get injured.
When the white bird drops it's egg the egg pushes up on the bird forcing it upwards.
Wow me
For our WOW ME! we figured out the speed of separation when red bird hits stone. To calculate this, we looked at newton's law of restitution. Newton's law of restitution states that the coefficient of restitution multiplied by the speed of approach is equal to the speed of separation. The coefficient of restitution is the relative speed after collision divided by the relative speed before collision. If the relative speed of red bird after collision is 12 m/s and the relative speed before collision is 23 m/s, we know that the coefficient of restitution is about 1 half. Now we have to multiply one half by the speed of approach. The speed of approach is 23 m/s, so we know that the speed of separation of red bird from stone is 11.5 m/s.
