It’s all about Inertia! Inertia says an object, the egg in this case, will stay at rest, unless an outside force acts upon it, your hand in this case. When you move the pie pan with your hand, gravity takes over and pulls the egg straight down into the glass of water.
How did gravity and air resistance affect the egg drop experiment?
A falling object (egg) has a downward force acting on it due to gravity. Air resistance acting on the falling egg results in an upward force, and these 2 forces oppose each other.
What forces affect the egg when it is dropped?
When dropped, the egg is accelerated by gravity. When the air resistance (the force experienced when placing one’s hand out in a strong wind), which increases with increasing velocity, equals gravity, the egg’s velocity will remain constant. This velocity is known as terminal velocity.
Why does an egg break when dropped physics?
Gravity causes an object to fall to Earth when dropped. Drop an egg from eye level so that it breaks. When the egg hits the ground with a given force, the ground exerts the same force back on the egg. The faster the egg falls, the greater this force is.
Why does an egg not break when dropped on soft foam?
The egg dropped on the pillow slows down and stops more slowly since the pillow is squishy, therefore the force on the egg is smaller and the egg does not break. (The pillow also spreads the force over a larger part of the surface of the egg, which also helps save it).
What is the best way to protect an egg in an egg drop?
- Slow down the descent speed.
- Cushion the egg so that something other than the egg itself absorbs the impact of landing.
- Orient the egg so that it lands on the strongest part of the shell.
How does impulse relate to egg drop?
When you drop the egg, it speeds up as it falls, and as it speeds up, it is gaining momentum from the impulse caused by the force of gravity. When it hits the floor or the pillow, it stops due to an impulse in the opposite direction.
What type of collision is egg drop?
Elastic Collision BUT: Air resistance becomes negligible when the object falls at a constant speed and is no longer accelerating, also called terminal velocity.
What is the independent variable in an egg drop experiment?
The independent variable in all of this was the speed of the egg and the impact time of the egg, while the dependent variable was force. The controls are the materials used and the mass of both the container and egg.
How does Newton’s 1st law apply to egg drop?
What are the best materials for an egg drop?
- Raw egg, or other payload that needs protecting.
- Container, like a cardboard tube, cup, box, etc.
- External protection materials, like balloons, rubber bands, craft sticks, straws, etc.
- Internal padding, like fabric, packing materials, paper, etc.
- Pen or pencil.
- Paper.
- Tape.
- Scissors.
Is energy conserved in an egg drop?
At the end of the drop, the egg and rubber band system now possess less gravitational potential energy, no kinetic energy (it is not moving) and a lot of elastic potential energy due to the stretched rubber bands. This illustrates the Law of Conservation of Energy.
How does Newton’s 3rd law apply to egg drop?
Newton’s third law states that for every action there is a opposite and equal reaction. Our egg drop project demonstrates this by there being a simultaneous reaction but in the opposite direction, so when you drop the egg and it lands, an upward force will act on it.
Why eggs dropped on a carpet or a mattress do not break?
Because a carpet or a mattress is soft in comparison to the floor, the egg slows down and stops more slowly, resulting in less force on the egg, which prevents the egg from breaking.
How much energy is required for an egg to break?
Eggs would produce the cracks when suffering from an impact energy of 12-26 mJ.
Where is the strongest part of an egg?
The egg is strongest at the top and the bottom (or at the highest point of the arch), which is why it does not break when pressure is added to both ends. The curved form of the shell also distributes pressure evenly all over the shell rather than concentrating it at any one point.
Why does an egg break on concrete but not grass?
This question can be answered by thinking of the momentum of the egg as it makes contact with the concrete or with the grass. Note that the concrete is hard, and causes the egg to come to a complete stop in a very short amount of time, while the grass can yield considerably and slow down the egg gradually.
Can an egg break on grass?
If an egg is dropped on concrete, it usually breaks. If an egg is dropped on grass, it may not break.
What’s the hardest part of an egg shell?
Answer: The egg is strongest at the top and the bottom (or at the highest point of the arch). That’s why the egg doesn’t break when you add pressure to both ends. The curved form of the shell also distributes pressure evenly all over the shell rather than concentrating it at any one point.
What is the strongest egg?
One ostrich egg can take the weight of about 220kg vertically and 120kg horizontally. This means you can stand on ostrich eggs and they will not break. The egg shell is 2mm thick which sounds like nothing but is the strongest shell of any egg.
What does the egg drop experiment teach?
The egg drop project is a time-honored tradition in many science classrooms. Students build a device to protect an egg and prevent it from breaking when dropped. This project typically relates to lessons about Newton’s laws of motion or potential and kinetic energy.
Is momentum conserved in an egg drop?
The Vehicle increases the amount of time that the force of gravity is acting on the egg. The impulse equals the change in momentum so the only way to reduce it, is to reduce the initial momentum = mv because in the end it will be stop by floor and have zero momentum there. Conservation of momentum equals mv=mv.
Which egg experienced the greater impulse?
Which egg experienced the greater time of impact? If their momenta are equal before the collisions (same mass and velocity), both eggs experience identical impulses because both are stopped by the collision. The egg that hit the crash barrier experienced the greater impact force due to the shorter impact time.
What is the effect of the mass of an egg and its drop height upon the force it experiences?
What affect does doubling the mass of an egg have upon the force that the egg experience? Doubling the mass makes the force twice as large.
What things in nature are similar to this egg drop experiment?
Egg drop devices simulate parachutes and other similar features seen in nature, such as the helicopter seeds that are dropped from some trees.
