Explanation:
the significance of Newton's first law
Explanation:
Introduction
Research Question: What is the relationship between mass and inertia?
Age: High school and up
Safety Concerns: In this lab, you'll be hitting some objects. Make sure that you have plenty of room to work.
Time: 1 hour
Independent variable: Mass of the egg
Dependent variable: Qualitative analysis of inertia Control variables: Egg drop apparatus setup, force applied to plate, amount of water in cup
Imagine a tractor trailer barreling down the highway. On the same highway, a compact car speeds along. Which one would you rather collide with? Probably neither, but one vehicle is going to be much harder to stop than the other. Can you guess which one? You're probably thinking the large truck, and you would be right. But why are heavier objects harder to stop than lighter objects? The answer has to do with Newton's first law, which states that an object in motion tends to stay in motion. To review Newton's first law, you can watch this video lesson: Newton's First Law of Motion: Examples of the Effect of Force on Motion.
Newton's first law explains the concept of inertia, which is the tendency of objects to resist changes in motion. Today, we're going to see how the mass of an object influences its inertia. If you need to read up on inertia, you can do that in this lesson: Laws of Inertia: Definition & Formula.
Materials
Paper towel tube
Pie plate
12-ounce glass
12 ounces of water
Extra large egg
Small egg (still large enough to fit on top the paper towel tube)
Access to running water and soap
Balance
Data table:
Mass of egg Observations
Steps
1. Take the mass of both eggs and record this in your data table.
2. Fill your glass with 6 ounces of water.
3. Center the pie plate on top of the glass.
4. Next, center the paper towel tube vertically on top of the pie plate.
5. Gently place the smaller egg on the paper towel tube, making sure it sits on top of the tube.
Experiment setup
setup
5. You're going to smack the pie plate out from under the paper towel tube and egg. You won't touch the paper towel tube or the egg, only the pie plate. You might need to try this more than once to apply to appropriate force.
6. Repeat steps 2-5 with the larger egg and observe any differences compared to the small egg.
Safety Tip!! Raw eggs may contain pathogens.
7. If there are any breaks to your eggs, wash your hands and carefully clean up the spill with a cleaning product.
