Fizik 101 Lab

Fundamental sciences and engineering are largely based on measurements and making predictions using these data together with appropriate Physics Laws. One of the goals of PHYS 101- Mechanics Laboratory experiments are to teach how to make measurements and to determine the degree of uncertainity of measurements. In this concept, students are expected to interpret a series of collected data and apply Physics Laws to explain an observed motion.

Laboratory experiments start with ‘Experiment 0’ that is intended to teach the basics of measurement and calculations like unit conversion, unit prefixes, measurement error determination, error calculation and how to draw a graph.

In this page you will see short definitions of each experiment and the regulations of the laboratory sessions.

Laboratory Rules
A student who does not attend the laboratory will be graded zero.
A quiz will be given at the beginning of each laboratory session and it is not allowed to take quizzes after 5 minutes from the beginning of lab hours. (otherwise, quizzes will be graded zero)
A medical or accident report is required to have the right of make up experiment. (a maximum of two make up examinations are allowed)
It is not allowed to enter the laboratory after 15 minutes of starting.
In case where a student gets two zero graded laboratories, he/she will fail in the laboratory and the course as well.
Eating, drinking, smoking, and using mobile phone are not allowed during laboratory sessions.
A student must bring his/her laboratory materials, namely; laboratory manuel, a ruler, and a scientific calculator to each laboratory session.
A student who does not bring the above listed materials will not be allowed to the laboratory.
Students should be aware of the grading system of the laboratory as 5 points for quizzes and 15 points for laboratory reports.
A student who is not able to get 12 points in average upon completion of 6 experiments will fail in the laboratory and the course as well.


Experiment 0: Introduction

In the first lab session, the general concepts in physics like unit systems, conversions between unit systems are introduced and then the concept of “How to draw a graph” is given.

Experiment 1: Average Velocity versus Instantaneous Velocity


In this experiment,  the relationship between the instantaneous and average velocity is investigated.



Experiment 2: Initial Velocity and Time of Flight, Horizontal Velocity is Constant

In the first part of the experiment, the effect of the launch angle to the time of flight with different initial velocities is observed. Horizontal component of the initial velocity will be the focus of the second part of the experiment. Is it really constant throughout the entire flight?


Experiment 3: Newton’s Second Law

In this experiment, Newton’s Second Law is going to be tested by applying different forces to the cart without changing the total mass of the system.

Experiment 4: Potential Energy and Conservation of Energy

The subject of this experiment is the conservation of mechanical energy. You will observe how the mechanical energy is converted from sping potential energy to kinetic energy and to gravitational potential energy in an isolated system.
