PHYSICS UNIT 2 Physics P2 for GCSE Additional Science or GCSE Physics AQA GCSE Science PHYSICS 2 Unit P2.1 Forces and their effects Appreciate that forces can cause changes to the shape or motion of an object. Not only can objects can move in a straight line at a constant speed but they can also change their speed and/ or direction (accelerate or decelerate). Be able to use/produce graphs can help us to describe the movement of an object. These may be distance-time graphs or velocity-time graphs

Fawzi Abdelgani Ahmad . Experiment 1: Experimental Uncertainty (Error) and Data Analysis Jan/30/2013 PRELAB: 1. Do experimental measurements give the rule value of a physical quantity? Explain. No. Statistical methods are used to establish the deviations in the measurement. 2. Distinguish between random (statistical) error and systematic error‚ and give an example of each. Random errors are caused by unknown and unpredictable changes in the experiment like mechanical
Premium Measurement
Measurement and Uncertainty When recording data‚ each entry should be given a corresponding estimated error‚ or uncertainty. The uncertainty gives the reader an idea of the precision and accuracy of your measurements. Use the following method for finding the uncertainty associated with any measuring device used in lab. First‚ find the least count‚ or the smallest printed increment‚ of the measuring device. On the meter sticks‚ the least count is 1 mm. On the double pan balances‚ the least count

Module 1 Physics: The Basic Science What this module is about The study of science has two branches namely‚ the life sciences and the physical sciences. The life sciences include biology‚ zoology and botany. The physical sciences branch into areas such as geology‚ astronomy‚ chemistry and physics. However‚ physics is more than part of physical sciences because it does not only deal with matter and energy but it also deals with the other basic concepts like motion‚ forces‚ heat‚ sound‚ light

Newton`s Second Law – Lab Report Name: Tasneen Ahsan Date: 19th November‚ 2012 Purpose To show how the acceleration of an object changes when‚ the mass changes and the net force is kept constant and when the mass is the same.. Hypothesis I predict that by changing the mass of the object will result in a change in the acceleration as Newton`s second law states that the magnitude of the acceleration of any object is directly proportional to the magnitude

momentum occurs in each collision? momentum is always conserved. but you can calculate the vector sum p=mv of both objects before collisions after the collisions. your two vectors should be equal. 3. Write a complete conclusion for this lab. My purpose for this lab was to explore conservation of

Aim • To calculate the SHC of water • To see how accurately I can measure a known quantity Research Question • Will the experiment carried out give us a good approximation of the SHC of water? Hypothesis • The result we will get as the SHC of water will not be exactly the same as the literature value‚ but will be a very close figure to the literature value of the SHC of water as there will be some limitations to our experiment. Variables Independent: temperature of water Dependent:

“The Domino Effect” Teacher’s Prompt Investigate the domino effect with a set of dominoes. Aim To investigate the relationship between the mass of the dominoes‚ and how it impacts the time taken of the domino effect. Independent Variable: The mass of each domino (12.38 g‚ 32.38 g‚ 42.38 g‚ 62.38 g‚ 82.38 g). Dependent Variable: Time taken of the domino effect. Controlled Variable: The number of dominoes used (8 dominoes)‚ the distance between the dominoes (2 cm)‚ the loads used as the initial
