Transcript of The Physics Behind the Egg Drop

GOAL: Create a "package" that will protect a raw egg from breaking when dropped.
There are 5 major forces that can be applied to the egg drop
The Physics Behind the Egg Drop.
What is the best way to save an egg from breaking when dropped?
that any object will stay moving or stationary unless a force works to move or stop it
Applied to the egg drop:
during the drop the eggs will stay falling towards the ground unless there is a force to change its trajectory
Hint:
so when building a device to protect the egg, find a way change the way the eggs fall
Speed describes how fast an object is moving
the law explains...
ACCELERATION
.
the rate at which an object speeds up or slows down
a roller coaster has a much faster acceleration than a minivan
so when an egg is dropped, the longer it falls, the faster it accelerates therefore gaining more speed
for example.......
the roller coaster and the mini van can reach the same speed, but it takes the minivan longer than the roller coaster to get to that certain speed,
so the roller coaster has a faster acceleration
GRAVITY
gravity is all around us, its main purpose is to accelerate objects to the ground. That's why when an object is dropped it does not float, it goes straight to the ground.
Velocity
Velocity is speed with a specified direction
The elevator is moving at a speed of 3 mph towards the sky (positive direction)
Hint: best to design a device that will decrease the eggs velocity/speed when it hits the ground to minimize the force of the impact
When an egg is dropped it will have a gravitational pull on it sending it straight to the ground
What are the forces that can act on an object in free fall
A
force
is a push or pull upon an object
This results from interactions between objects
Any ideas?

When any object, for example an egg, is dropped it is considered to be in

free fall
When that egg is dropped there are many forces that influence the eggs movement, speed....etc.
Skydiving
Newtons First Law
An object at rest will remain at rest unless acted on by an unbalanced force. An object moving continues in motion with the same speed and in the same direction unless acted on by an unbalanced force.
Speed
a car driving on the highway goes 65 miles an hour
Newtons First Law
Speed
Velocity
Acceleration
Gravity
applied to the egg drop:

When the egg is in free fall it will be going at a high velocity/speed, which will result in the fragile egg breaking when it hits the ground.
