Introduction The purpose of this experiment is to determine whether a change in mass affects the acceleration of the cart. The independent variable is the mass of the weight and the dependant variable is the acceleration. I do not think there is a control in the experiment because we do not know an absolute result with any of the masses of the weight. Besides‚ if we used 0g as our control‚ the cart won’t even move. Hypothesis Under these conditions I believe that the results shown in the distance

Acceleration Worksheet 3 Worked Example A cheetah running at 20 m s−1 slows down as it approaches a stream. Within 3.0s‚ its speed has reduced to 2 m s−1. Calculate the average acceleration of the cheetah. Solve the following: 1. A sports car‚ accelerating from rest‚ was timed over 400 m and was found to reach a speed of 120 km h−1 in 18.0 s. a. What was the average speed of the car in m s−1? b. Calculate the average acceleration of the car in km h−1 s−1. c. What was

Determination of the Acceleration Due to Gravity By A Good Student Abstract The acceleration due to gravity‚ g‚ was determined by dropping a metal bearing and measuring the free-fall time with a pendulum of known period. The measured value is 9.706 m/s2 with a standard deviation of 0.0317‚ which does not fall within the range of known terrestrial values. Centrifugal forces and altitude variations cannot account for the discrepancy. The calculation is very sensitive to the measured drop

Introduction The Disbursement Acceleration Program of the Aquino Administration should not be implemented because it does not contribute in the GDP and economic growth of the country‚ although it may have been partially successful‚ its rediscovery has drawn reaction as “Unlawful”‚ aside from being unconstitutional‚ it does not serve‚ neither its spending was translated to over-all increase of jobs‚ nor trigger a downturn in poverty incidence. II. Background The Disbursement Acceleration Program (DAP) is a

Calculate the value of t when Q is due north of P. (2) (Total 8 marks) 2. A train starts from rest at a station A and moves along a straight horizontal track. For the first 10 s‚ the train moves with constant acceleration 1.2 m s–2. For the next 24 s it moves with constant acceleration 0.75 m s–2. It then moves with constant speed for T seconds. Finally it slows down with constant deceleration 3 m s–2 until it comes to rest at a station B. (a) (b) (c) Show that‚ 34 s after leaving A‚ the speed

The Effects of Force and Mass on an Object’s Acceleration Abstract: In this lab there were two principals investigated. The first was the relationship between applied force and acceleration. The second was the relationship between mass and acceleration. To study these two relationships‚ my partners and I used a dynamic cart with added mass on it. This cart was then attached to a pulley system on a “frictionless track” where it was pulled by a string bearing mass over the edge
