SAMPLE PROBLEMS: 111-SET #1 VECTOR ADDITION‚ SUBTRACTION 01-1 1). A man is able to row a boat at 3 mph in still water. If he rows his boat pointed straight across a river with a current of 4 mph‚ what is his net velocity? If the river is 0.5 miles wide‚ at what point will he land on the other side? Solution: The first step in problem solving is to identify the problem type. In this problem we are asked for a ‘net velocity.’ Since velocities behave as vectors‚ then we have a vector addition

We can relate physics to softball in many different ways. It is actually hard to not think about the game of softball without some physics in mind. Specifically‚ the ideas of momentum and energy helps define the way softball works and why it works. Momentum Running: When running the bases in softball‚ there is a lot more to it then the average person would think. While we run the bases‚ we are changing our momentum by applying more force‚ the force of friction‚ onto the ground which causes more

AS Level Physics: Terms & Definitions:- Measurement Random errors are errors of measurements that result in a scatter of readings about a mean value. Systematic errors are errors of measurement which occur according to some fixed patterns such that they consistently give out an over-estimation or under-estimation of the true value. Accuracy is a measure of how close the results of an experiment agree with the true value. Precision is a measure of how close the results of an experiment

Physics can be related to sports and fitness on many different levels. When you lift weights‚ play sports or even buy athletic equipment you probably don’t know how much physics was really put into any of it. Weightlifter’s need to know which workout is better. Also the equipment athletes use relate to physics. Manufactures design equipment for athletes‚ which involve physics. The manufactures need to think about what will make the object better and what materials will cause the equipment

8th physics light reflection refraction eyes defect and dispersion The ray of light which falls on the mirror surface is called incident ray. The point at which the incident ray strikes the mirror is called the point of incidence. The ray of light which is sent back by the mirror is called the reflected ray. The ‘normal’ is a line drawn at right angles to the mirror surface at the point of incidence. The angle between incident ray and normal is called the angle of incidence. The angle between

Physics of Volleyball Physics is the study of energy and how it is transferred from one particle to another. There is certainly a lot of energy transferred between objects and players in the sport of volleyball. A few of the concepts of physics that take place during volleyball include gravity‚ displacement‚ velocity‚ acceleration‚ projectile motion‚ and force. These concepts are displayed throughout the different positions on the court. There are three main aspects of volleyball that include
