However, if an object were shot out of a gun for example , in a horizontal direction , then the force of gravity would directly act upon the object on its descent . When an object is projected at a specific angle, then your v is no longer v. In other words your final velocity is not equal to your initial velocity . The equation v=v cos is used. Experiment overview: In this lab , my partner and I performed multiple attempts to calculate the average distance a projectile would travel before hitting the ground when shot out of a gun in a horizontal direction . In the first trial , we shot the circular metal ball out of the gun at an angle parallel to the ground(0).The gun , itself , had three levels of compression .
Newton’s Second Law Lab Purpose: The purpose of this experiment was to determine the relationships between mass, force and acceleration as well as to prove Newton’s second law Hypothesis: It was hypothesized that there would be an inverse relationship between acceleration and mass; as the value of the mass increased the acceleration decreased. As well it is hypothesized that there would be a direct relationship between the net force and acceleration; as the net force increases the acceleration increases as well. Materials & Method: The materials that were required to do the experiment were a metre stick; its purpose was to measure the amount of string that is going to be used to drag the cart. Next equipment needed for the lab was a dynamic cart; it was going to be dragged by the string with a mass on the other end and will find relationships between these two. Also string (about 75cm) was needed in this experiment which would help pull the cart with the help of the masses that were used.

Lab 9 Formal Report Abstract In this report, we begin our studies on oscillations that repeat themselves. This lab will attempt to prove theories based around idea conditions for period motion where mechanical energy is conserved. First, using a simple spring oscillator will allow us to show this motion relative to an equilibrium point described by its angular frequency. Then, other forms of oscillations will be observed using a rod pendulum and wooden pendulum. Lastly we will explore standing waves and how string oscillations become affected by the string mass density.
Howard University Washington, D.C. Department of Mechanical Engineering “Strain Hardening “ Lab 2 By Theron Lewis For Professor H.A. Whitworth October 3rd, 2011 Table of Contents ABSTRACT Work hardening (or strain hardening) is the strengthening of a metal by plastic deformation. This phenomenon occurs because of the altering of the material’s crystal structure through dislocation movements. Work hardening is used extensively in metalworking, where one intentionally induces plastic deformation to increase strength and change its shape. These processes are also known as cold working.
Projectile Lab Experimental Techniques Finding the Velocity: The first step in this lab was to find the velocity of the projectile launcher. The launcher was set to setting to and attached to the double photo gate. Next, the USB cable was hooked up to the photo gate and plugged into the computer so the data could be retrieved from Data Studio. Finally, the projectile was launched, using the projectile launcher, straight up from the ground and through the double photo gate. The projectile was launched three times and an average velocity was found.
IBDP Physics Practice Lab - Factors Affecting the Drop Time of a Falling Body By Clevis Tam Aim: To investigate how the relationship of the terminal velocity of a falling parachute depends on the mass of the clay. Variables: • Independent Variables: The mass of the Clay (g) • Dependent Variables: The time the clay takes to reach the ground (s), The speed of the clay that is processed after collecting data (ms -1) • Controlled Variables: Method of releasing the clay, the area of the parachute Materials / Apparatus: 1. Meter Ruler (0-1m, measures to 0.001m) 2. Electronic Stopwatch (measures to 0.01s) 3. Drop Height (2.56m) 4.
We used a vernier caliper to obtain the diameter of those two and therefore, the radius. When adding all the numbers together, we found that the true radius(r) of the orbit was 0.139 m. To find our tension, we needed to find out how much weight we needed to pull the object towards away from the spring and on the tip of the pointer as shown below. The tension needed to pull the mass on the tip of the pointer 1.05 kg. In theory the force of acceleration needed to pull the mass to same exact spot should equal the force of tension multiplied by the force due to gravity. Using Newton’s second law, F=ma, we know that the

m_2 a=m_2 g-T T=m_2 g-m_2 a Equating the tensions m_1 a=m_2 g-m_2 a m_1 a+m_2 a=m_2 g (m_1+m_2 )a=m_2 g a=(m_2 g)/(m_1+m_2 ) The acceleration is the same acceleration described in the kinematics equation a=2s/t^2 For a body starting from rest, s is the distance traveled by the cart and t is the time of travel. We had objectives to meet by the end of the experiment. First of which was to verify the direct proportionality of acceleration and net force if the mass of the body is constant. Meaning, if the acceleration value increases, the net force of the mass must increase as well, given the fact that the mass of the body is constant. The second is to verify the inverse
