Abstract: An experiment was done to determine acceleration due to gravity. A track was prepared to let a cart go upwards by a slight hand push and get backwards by gravity. The movement of the cart was measured by an ultrasound sensor. The sensor sent the data to a software called “DataStudio”. The software was to draw a Velocity-Time graph and could determine the gradient of the graph (Change of Velocity over a time interval or simply the acceleration). The angle of the track was changed 9 times

relating to gravity. A capital G indicates the gravitational constant‚ as explained in the article GRAVITATION. A lower-case g stands for the acceleration imparted by gravity at the earth’s surface. An acceleration of 1 g is 32. 1 feet per second per second (9.8 m/s2). Fliers and astronauts may experience accelerations many times larger than 1 g. These accelerations are usually expressed in multiples of g‚ such as 2g‚ 3g‚ etc. For example‚ when the speed of a space vehicle increases 96.3 feet per second

set number 1- Palak Sharma Distance a scalar quantity that refers to “how much ground an object has covered” during its motion. Formulas used: Newtons laws are: (1) Every object moves in a straight line unless acted upon by a force. (2) The acceleration of an object is directly proportional to the net force exerted and inversely proportional to the object’s mass. (3) For every action‚ there is an equal and opposite reaction. Formulas used: F=ma Displacement is a vector quantity that refers to

Potholes are caused due to poor quality and badly maintained roads. The constant movement of the overweight vehicles like trucks is also responsible for these ill roads. This ill quality roads will cause severe damage to the vehicles in terms of tyres and the shock absorbers and most important thing is the accidents which is caused due to this. A system called Pothole Detection System which detects holes on roads or uneven roads. So that it helps in maintain the roads in a good condition. Here two

m_saadat@sharif.edu Abstract Handling behavior of a ground vehicle is one of main properties of a vehicle that play an important role in technical and commercial evaluation of a vehicle. The frequency weighted mean square value of the vertical acceleration is a well-known criterion for ride comfort. For handling‚ several criteria have been put forward‚ which are to a more or lesser extent dependent on driver input and each car company select some of these criteria as major criteria for their design

free fall‚ the only force acting upon it is gravity. The object used in this experiment was a golf ball that provided some acceleration when dropped. A sensor positioned underneath a table recorded the golf ball’s pattern of motion‚ when dropped. The main objective of performing this experiment is to measure the velocity and position of the ball to eventually find the acceleration of free fall. A computer program called‚ DataStudio‚ was used to create a graph of position vs. time and a graph of velocity
