With this lab we have demonstrated our knowledge of Newton’s 3 law, initially with the test mass inside the elevator at rest, it observe through the first and third Newton's law (law of inertia and law of action-reaction) that the mass on the scale will present an initial state in balance of forces, where the scale, the which measures the normal, will register the weight because in that state the normal and the weight coincide. Subsequently, according to elevator movement this balance will tend to alter. Given Newton's second law (law of movement) explains the change, the which will be reflected in the change of normal recorded by the scale.
This lab is about demonstrating our knowledge of Newton’s 3 laws by describing the forces that act on a person when riding in an elevator on a trip both down and then a trip back up.
My hypothesis is that when we are on our trip down at the beginning the mass is going to decrease a bit then when, we are at a constant velocity in the middle, the mass will be the same as the one we measured at rest outside and then when we are slowing down to stop the mass should increase a bit. Then on our trip up the opposite should happened at the beginning it should increase, the remain at rest and at the end it should decrease.
· Elevator
· Bathroom scale
· Slow-motion camera/phone (optional)
1. At first you should get the bathroom scale and measure the mass of one of your members of the group. You should do this outside the elevator because you wont have time to measure the mass once you are inside.
2. When you are ready to get into the elevator prepare the slow motion camera.
3. Get inside the elevator and put the bathroom scale on the floor then the person who was before weighted should stand in the bathroom scale....


A physics lab report for grade 11 class - physics - report

2395 words - 10 pages of the target using all that I had learned about projectile motion. This lab was a very interesting and quite a rewarding experience. It really changed the way in which I understand projectiles. Being able to relate to physics directly to real life experiences, and apply learned principles to a lab, such as this one, helped me form connections between theory and application. Although I will not be needing to calculate accuracy with a gun in real

Lab Report: Local Gravitational Acceleration Lab - Physics - Assignment

575 words - 3 pages trial 1 our average was -10.20m/s2 with a Standard deviation of 0.01866. For trial 2 our average was -10.18m/s2 with a Standard deviation of . Our measure of gravity was only 7% off from what it was supposed to be which is -9.8.m/s2 Suggestions for Improvements The only issue we faced during this lab was with the use of the GLX Xplorer program. Our setup was fine and everything seemed to be up and running but we had a little difficulty

874 words - 4 pages The Pendulum 7/11/2017 Purpose: The pendulum can be described as a weight suspended from a pivot so that it can swing freely. We know that a long pendulum will perform a simple harmonic motion. A whole oscillation for this pendulum is called period referred as T. The objective of this lab is to learn how to obtain the period of a pendulum that swings freely in a simple harmonic motion. By doing this we will better understand how the period

Sense Perception’s Role in Natural Sciences - IB TOK 12 NWSS - Assignment

429 words - 2 pages sciences, often times when performing lab activities in chemistry and physics, one must read rulers or observe volume in a graduated cylinder. The use of human eyes to perform these tasks can introduce errors as the human eye may not be able to read these measuring tools precisely or accurately. This is another example of how sense perception may be unreliable in natural sciences. However, as natural sciences deal with the natural world
