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.
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
We will start at 0.1 meters and then increase the distance by 0.1 meters each successful measurement until we are no longer able to get acceptable measurements. As we were conducting the experiment, the farther the second light beam sensor was moved down the shaft the more vertical the shaft need to be in order for the ball to pass between both of the light sensors to achieve an accurate measurement. We were able to easily achieve an accurate measurement at a distance of 1.6 meters. The distances and the measurements were entered into a excel spreadsheet and plotted on a scatter chart. The time measurements were put on the X axis and the distance measurements were put on the Y axis.

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. The SI unit for force in the above equation is Newton (N), SI unit for accelerations is metre per second squared (m/s2) and the SI unit for mass is kilograms (kg). The objective of this experiment was to show the relationship between acceleration and force in a frictionless environment and to show the concept of mass (Lab#1). Other equations used in this experiment were: V22 = V12 + 2ad; used to find the acceleration for each weight V1 = Lt1 and V2 = Lt1; both used to find the acceleration Materials * Two vernier photogate timers * String * Glider * Blower * Air—cushioned track * Weights and Hanger * Pulley and clamps * Vernier Lab Pro Procedure and Observations 1. Two photogate timers, 60 cm apart, were set over the air track.
I. Objectives: a. Examine the relationship between the force that maintains circular motion, the radius, and the tangential speed of a whirling object. b. Construct a device for measuring the tangential speed of an object undergoing circular motion, and you will determine how the force and the radius affect the tangential speed of the object. II.
Aim of experiment (1.1) The aim of this experiment is to show that the force exerted by a jet of fluid striking onto an object is equivalent to the rate of change of momentum in the jet. It is possible to observe the shape of the fluid after the impact with the flat plate. Apparatus (1.2) Impact of a jet apparatus Steady water supply with a flow control valve A flat plate Set of calibrated weights Stop watch Theory of experiment (1.3) In this experiment the rate of change is calculated directly from the change in momentum rate of the fluid before the fluid hits the plate and after the fluid hits the plate. This is a diagram of the straight plate and what will happen as the fluid impacts on the plate. Before the impact of the fluid onto the plate, the fluid is in line with the x-axis, as shows by the velocity vector labeled V1.
The materials we used were 6 steel ball bearings, a U-track, meter stick, and triple beam balance. Objective: The objective of this Energy and Momentum lab is to find out the loss of kinetic energy due to the friction. Also we are trying to find the loss in kinetic energy through and semi elastic collision. So we are undergoing this experiment to find out what we want and then if our losses are consistent then our systematic error can be removed to analyze our data. Now we can leave out un-useful energy so we would be efficient.
The slope on a Distance vs. Time Graph is based on a scalar quantity and is used to judge speed because it has a magnitude and direction. The slope also represents the speed in the distance traveled over a certain time. To find the slope you can measure the distance the object has traveled every second similar to like
