Is an egg a controlled variable?
Is an egg a controlled variable?
Controlled variables are things that you keep the same in all of your tests. This might include the temperature of the eggs (room temperature vs. fridge), type of vinegar used (e.g., white vs. apple cider), and kind of egg (e.g., chicken vs.
What forces are involved in an egg drop?
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.
How can you control the forces that cause the egg to break?
How can you control the forces that cause the egg to break? Gravity cannot be controlled, but it can be contradicted by air friction. To control air friction, surface area can be increased, as done by the fabric surrounding the box. Wind can be dealt with by avoiding it, or making the model stable.
What is a controlled variable example?
Examples of Controlled Variables Temperature is a much common type of controlled variable. Because if the temperature is held constant during an experiment, it is controlled. Some other examples of controlled variables could be the amount of light or constant humidity or duration of an experiment etc.
What is the physics behind the egg drop experiment?
The cup drop illustrates the transfer of potential energy to kinetic energy. The potential energy from the eggs transfers into kinetic energy after an outside force (gravity) acts upon the egg.
What are the factors that affect the motion of the egg as it fall?
Force, Mass and Acceleration Gravity causes falling objects to accelerate at a rate of 32.2 feet per second squared. By reducing the amount of mass in the egg container, you are reducing the amount of force it exerts as it falls.
What is the physics behind the egg drop?
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.
How do Newton’s laws apply to egg drop?
Newton’s First Law, once the egg was moving, it didn’t want to stop. The container of water interrupted the egg’s fall, providing a safe place for the egg to stop moving so you could recover it unbroken. The gravity-pushed egg caused the water to splash out.
What is an example of a control variable?
In an experiment to observe the growth of a plant, the temperature can be classified as a control variable if it is controlled during an experiment. Other examples of control variables could be the amount of light, duration of the experiment, amount of water, and pot of the plant.
