# Acceleration Of Gravity

Improved Essays
In this experiment the main goal is to examine the correlation between position, velocity, time, and acceleration of objects, moving in one or two dimensions. Each and every experiment will be conducted under different conditions. For example, the first experiment requires a constant force (gravity) to act on the object, the picket fence. This experiments other condition is that we neglect friction. This object should be in nearly ideally circumstances. In the second experiment, the conditions are slightly different… In the third experiment, projectile motion…
Experiment # 1 – Measuring the Acceleration of Gravity

The object in motion is said to be in free fall. That is because the only force that is acting on the object is said to be the
Using kinematic equations, you will determine where a target will land. This experiment ignores air resistance. This projectile is launched with a speed of v(0) at an unknown angle. Therefore, the shape of the motion is predicted to be parabolic.

Procedure
The nerf gun is set up to a ring stand at approximately 50 cm above the table. Pick an unknown angle other than 0 or 90 degrees to launch the nerf bullet. Adjust the launcher so that it projects the projectile onto the table. For the first portion of the experiment the angle that you choose will remain constant throughout the experiment. A measurement from the height of the table to the nerf gun describes the launching position that should be recorded. The nerf gun bullets will have a weight to them so that they wouldn’t go too far. Place a piece of paper with a target drawn on it on the table. It should be 25 cm away from the ring stand. The nerf gun should be fired many times so it can land close to the target area. Repeat two more times with two other unknown angles. With all the information compiled you can calculate the speed at which the projectile was launched as well as the range in the horizontal

The first problem lies within Heisenberg’s uncertainty principle. In order to record information about every particle in a person’s body, we need to know exactly where those particles are and exactly how fast they are moving. However, Heisenberg’s Uncertainty Principle tells us that this is an impossible task. Whenever you look at any atom or molecule, you have to shine light on it to observe it. Shining light on the atom means shooting photons off of the atom.…

The tangential component of the force is responsible for moving the particle along the path. From Newton’s second law of motion for normal and tangential axes, we have F_t=ma_t From the kinematic relation, we know that at = vdv/dx, so we can write the above equation as Fig. 2.7 F_t=mv dv/dx F_t dx=mvdv We already know that the first term in the above equation is work due to a force and it is a scalar term. So we write the equation in scalar form. If the particle has initial position x1, initial velocity v1, final position x2 and final velocity v2, we have ∫_(x_1)^(x_2)▒〖F_t dx〗=∫_(v_1)^(v_2)▒mvdv ∫_(x_1)^(x_2)▒〖F_t dx〗=(mv_2^2)/2-(mv_1^2)/2 The first term in the above equation is the work done by a force and the second and the third terms are kinetic energies of a particle.…

In the m9c free fall acceleration lab we were to determine if mass or distance of an object falls effect on gravitation acceleration that the object experiences. The experiment was used to investigate the theory weather the heavier the object that it is will fall faster or not. The method that was used to find gravity was through the derived version of kinematic definitions. The overall result in the experiment concluded that distance and mass does not effect on the gravitational acceleration that the object experiences, either a heavy item or light weight item falling at the same point will land at the same time due to gravity. When people think of a physic quote, one that usually comes to mind is what goes up must come down.…

By factoring in the height, the thing is expected to reach and the velocity with which it is projected, and accounting for gravity, it is possible to determine fairly precisely where the projectile is likely to land. The military uses the quadratic formula all the time to decide where missiles are likely to fall and to target flying objects.…

Force is a vector which is a directional arrow; meaning that force is only applied in conjunction with direction. An object is considered to have a net force acting on it if there is an unbalanced force, e.g. 20N force right and a 50N force left would result in a 30N force left. Newton’s Law Three states ‘For every action, there is an equal and opposite re-action’ (National Aeronautics and Space Administration, 2015). This explains the concept of interactions between objects.…

Through this use, the calorimeter constant can be calculated, as well as the heat capacity of the system of the calorimeter. These various techniques are all put to use to calculate for unknown values that do not appear in a standard table or entry. It is the study of calorimetry that makes it all possible. Hence, in this experiment, a bomb calorimeter will be used to determine the change in energy and the change in enthalpy of naphthalene. These two values are the goal for the experiment and through the manipulation of the data, they will be achieved.…

In this methodology, the energy of TNT was supposed to be abruptly released inside the front of detonation wave. Detonation process requires to model the movement of the products of detonation after they reach subsequent specific locations by the detonation wave front. Detonations have a faster reaction zone than the sound speed. Progression of blast waves has been presumed to be perpendicular to the corneal surface unless differently specified and the eye in primary position, (i.e. : staring at the explosion).…

Results H1 H2 Landing spot ( ) Actual value (landing spot) Trail one .26m .904m 96.96cm 96.8cm Trail two .235m .904m 92.18cm 92cm Discussion questions 1) Equation for the landing point of the bob 2) Distance where the bob should land from directly beneath the rest position of the pendulum. 3) Would you expect the same result if you used the different mass? If the experiment were to use a different mass the result would not differ as the length that the mass travels is independent on both the mass of the objects and the gravitational force which is acting upon it. However the landing position of the mass is dependent on the heights (h1 and h2). 4) How would your results…

Personal Write up For this lab, bottle rockets were to be made by the materials of duct tape, a tennis ball, cardboard, and a liter bottle. Using water as fuel, the rocket that is constructed was launched at the pressure of eighty PSI. The objective of this lab was to build the rocket efficient enough to launch at a range of two hundred to three hundred feet by calculating different variables. The independent variables of this lab were the shape and mass of the rocket, the angle degree the rocket is positioned at, and the amount of water added the rocket. The dependent variables were the distance, and the time.…

How much energy is lost? note: the initial velocity calculated using kinematics should equal to the initial velocity calculated using momentum, meaning the initial velocity in apparatus 1 should equal to the initial velocity on apparatus 2. Background: In this lab I will be exploring and examining not only inelastic collision, but also momentum and energy. I made my own model of the ballistic pendulum, using toy gun, retort stand and a handmade ball catcher. I will take out the ball catcher from the pendulum and fire the ball, and find the height of the toy gun above the floor before release and the horizontal distance that the ball landed, then I can calculate the initial velocity using kinematics, refers to apparatus 1.…
