What is Physics? Physics is a field of science that shows the interaction between matter and energy. It shows physical processes that help us understand better how our universe behaves. Physics also use scientific method that formulates and tests hypothesis which are based on observations and comprehensions. What are the different fields under Physics? PHYSICS PHYSICS dealing with physical processes and their relations in the science of physical chemistry. dealing
Premium Science Physics Scientific method
Physics (from Greek)‚ i.e. "knowledge‚ science of nature"‚ from φύσις‚ physis‚ i.e. "nature"[1][2][3][4][5]) is a part of natural philosophy and a natural science that involves the study of matter[6] and its motion through space and time‚ along with related concepts such as energy and force.[7] More broadly‚ it is the general analysis of nature‚ conducted in order to understand how the universe behaves.[8][9][10] Physics is the field of science that studies the physical world. From the large (galaxies

Physics Formulas: Mechanics Mechanics is the oldest branch of physics. Mechanics deals with all kinds and complexities of motion. It includes various techniques‚ which can simplify the solution of a mechanical problem. Here are some of the often required physics formulas falling in mechanics domain. Motion in One Dimension The physics formulas for motion in one dimension (Also called Kinematical equations of motion) are as follows. (Here ’u’ is initial velocity‚ ’v’ is final velocity‚ ’a’ is

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

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

In this experiment a steel ball will be shot into the bob of a pendulum and the height‚ h‚ to which the pendulum bob moves‚ as shown in Figure 1‚ will determine the initial velocity‚ V‚ of the bob after it receives the moving ball. If we equate the kinetic energy (KE) of the bob and the ball at the bottom of the potential energy (PE) of the bob and ball at the height‚ h‚ that they are raised to‚ we get: KEbottom = PE top ½ (M + m)

For task 1‚ we just became familiar with DataStudio and learned how to use it to time each “swing” of the ball on the end of the pendulum. Then‚ in task 2‚ using the materials provided we decided that the variables that would have effect on the period are the length of the string‚ the angle the ball was released‚ and the size of the ball‚ which was either the wooden ball or the steel ball. Since we were measuring the length of the string vs. the mean time of each swing of the pendulum‚ we kept

4s and the reaction time while someone is distracting the member is 0.5s‚ and lastly graph matching. 1. Introduction All of us have the ability to move. Knowing how to describe motion is an important first step in understanding the underlying physics that governs changes in motion. We see changes in motion all the time‚ as we go to work or school‚ participate in sports or even wander around our homes. If we never changed our own motion‚ we would never make it out of bed in the morning. The study
