Egg car crash project

There are a variety of ways to conduct an egg drop.

Egg car crash project

Drop an easily breakable object, Egg car crash project as an egg, into a safe container, like a transparent bucket, making sure all students can see what happens.

Why did the egg break? What caused the object to move in the first place?

Let students explain what they know about this. Expect some to say that gravity caused the egg to fall and that eggs break easily. We can understand why it broke by understanding mechanical energy. What happens in a car accident? For a car moving at around 35 mph, the driver is also moving at 35 mph.

However, in the event of an accident, the driver inside must slow down to zero mph as smoothly as possible. Otherwise, the result would be the same as flinging a body at 35 mph at a brick wall In today's lesson, we will look events, such as a car crash in this case, and examine the different ways energy is transferred in the systems.

From an engineering standpoint, situations such as these are interesting because seatbelts, force limiters, airbags and even the chassis of a car all work together to keep the driver and passengers safe in a car accident.

Energy can neither be created nor destroyed. This concept is further described on the DOE website. Potential Energy - Any energy that is stored is potential energy. Batteries, springs, and rubber bands are examples of stored or potential energy. In the associated activity, height provides gravitational potential energy.

For instance, a ball 1 foot above the ground possesses less potential energy relative to the ground than the same ball located 20 feet above the ground.

Mechanical potential energy is energy related to the position or location of an object not the energy of motion itself. The amount of potential energy an object has is also related to its mass.

For example, it is harder to lift a bowling ball 5 feet off of the ground than it is to lift a tennis ball 5 feet off of the ground.

Kinetic Energy - Energy associated with a moving object and is directly related to potential energy. Potential energy is transferred into kinetic energy when an object is let go from a particular height and begins moving.

Any object in motion has kinetic energy. You may want to bring in various objects of different sizes and weights and drop them to demonstrate how the differing amounts of potential energy are transformed into various amounts of kinetic energy as the objects accelerate towards the ground.The Physics of an Egg Drop 2 2.

Force = Mass times acceleration. The egg will accelerate based on the pull of gravity.

How much it accelerates depends on the height from which the egg was dropped and the mass of the egg and protector. Force will increase.

Although you can include anything in your design that will directly or indirectly protect an egg, you cannot interfere with the speed of the car. Build your prototype safety device for the toy car. Test out your prototype without the egg to determine if it meets the criteria and the constraints.

Founding Class of 2018 // The future starts now.

2 Designing an Egg-cellent Race Car. The egg drop experiment can have many variations. This is the one I like best. I have used it for a number of years, made some adjustments along the way, and think it's finally time to share with you.I use this project as a way to make the mathematics part of physics relevant to my 7th graders.
