To analyse this further, we can observe Newton’s first law of motion. Newton’s law describes how an object in motion, remains in motion. This is why the roller coaster continues going up the slope [1]. However, the KE is lost, as gravity takes effect and
Newton’s Second Law 3/6/2014 Purpose The purpose of this experiment is to determine the acceleration of gravity using Newton’s second law. Equipment * Air track, used to place other equipment on to test. * Cart, used as the bigger mass in the experiment. * String, attached to the bigger and smaller masses. * Paper clip, used as a hanger for the smaller mass.
I. Bean Bag Isotope II. The purpose of this experiment is to investigate the mass properties and relative abundance of isotopes for the “bean bag” element and to calculate the atomic mass of this element. III. Pre-Lab Questions A. The first possible property of electrons and protons that led to their discovery was their “positive rays,” positively charged streams of atoms generated in gas discharge tubes from J.J. Thomson’s experiment.
DEPARTMENT OF PHYSICS LAB REPORT FOR Title of Experiment: Newton’s Second Law Experimenters: Authors of this Report: Experiment Performed on: Monday, January 28th, 2013 Report Submitted on: Monday, February 4th, 2013 Teacher’s Assistant Name: Objective and Background Newton was the first one to identify the connection between motion and force. Newton’s second law of motion states that acceleration is dependent on two variables; the net force (F1 + F2 + F3 + F4 +...) and mass. This law states that the acceleration acting on an object is directly proportional to the net force and is inversely proportional to the mass of an object. For example; heavier objects require more force to move the same distance as lighter objects. Newton’s second law of motion is expressed as a mathematical equation: Fnet = ma (Force = mass*acceleration) A significant notion of this equation is that an object accelerates in the direction of the new force, and acceleration is created by the net force.
2. "F = ma: the net force on an object is equal to the mass of the object multiplied by its acceleration." 3. "To every action there is an equal and opposite reaction." To prove the 1st law, you can see that the air released from the balloon disturbs the state of rest of the car and makes it move.

In the start of the lab, the students had to wear ballistic eye protection (goggles). A ball was diameter was taken of the ball (in cm).
And third, does force have an impact on the distance the projectile travels? Upon completion of my research, it can be concluded that the length of the arm of the trebuchet and force does affect the distance a projectile will travel. Trebuchets are simple structures consisting of two A-frames with an axel between them. Around the axel is a lever arm that pivots. One end of the lever is shorter and carries a counter weight; and on the other end is a sling that carries a projectile.
Speed of sound in air using Resonance Purpose: In this laboratory investigation, we will determine speed of sound using the formula: speed = frequency times wavelength. Equation 1 After making several measurements of the speed of sound, we will compare our average experiment result from this lab to the speed of sound predicted by the equation vsound=330 m/s+.6m/s (T).Equation 2 Theory: Congitudinal waves are waves which the motion of the individual particles of the medium is in a direction that is parallel to the direction of energy transport. The result of a longitudinal wave is the creation of compressions and rarefactions within the air. Picture: The speed of sound in air is impacted by the temperature because sound travels by vibrating molecules and passing the energy on to a nearby molecule. Sound travels faster through warm air than cold air because the molecules in warm air vibrate faster.
To determine the free-fall acceleration g from a graph of acceleration vs. sine of track angle. • measure the acceleration of a rolling cart on an inclined plane with a motion detector; • change the angle of the incline and measure the acceleration for different angles; • determine how the acceleration depends on the angle and the gravitational acceleration Measuring 'g' experiment. The purpose of this experiment is to measure the acceleration due to gravity and to see if the effects of air resistance can be observed by dropping various balls and recording fall times.. Moment of Inertia The purpose of this experiment is to determine
Chapter 3: Linear Motion (Questions 20 and 22) 20.) Suppose that the three balls shown start simultaneously from the tops of the hills. Which one reaches the bottom first? Explain. Answer: -Of the three balls that are rolled, the ball in the middle should reach the bottom first strictly based on the fact that it travels down a steeper slope at the beginning, resulting in a faster acceleration then the other two balls.
