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

versa. 3. As I observed when we sat perpendicular to the seat It gave us less sensation compared to when we’re leaning back. I think it is because of air resistance. We have less air resistance when we are leaning backwards so it gives us a sensational feeling compared when we are sitting perpendicular our bodies counter the force that air resistance gives so it gives us less sensation. 4. RIDE WAS UNAVAILABLE 5. While riding the Flying Fiesta and Up‚ Up and Away I felt the force was

Plasma Complexity! Plasma is said to a substance similar to gas in which a certain portion of the particles are ionized. The basic premise is that heating a gas dissociates its molecular bonds‚ rendering it into its constituent atoms. Further heating leads ionization‚ turning it into plasma: containing charged particles‚ positive ions and negative electrons. The presence of a non-negligible number of charge carriers makes the plasma electrically conductive so that it responds strongly to electromagnetic

the ball is also moving. Q4: What is meant by scalars and vectors? Answer: * Scalar Quantities: Quantities that require magnitudes only to specify them are called scalar quantities or scalars. Mass‚ length‚ time‚ temperature‚ angle‚ area‚ speed‚ distance‚ volume and density are examples of scalar quantities. * Vector Quantities: Quantities that require both magnitudes and direction to specify them are called vector quantities or vectors. Displacement‚ velocity‚ force‚ momentum‚ weight

The Physics of Balls Bouncing off at Surfaces Leader: Mr. Edrian Pantas Contador‚ Love S. Members: Espiritu‚ Ian Timothy Ecube‚ Lynn Kristine Magangcong‚ Ahlya Oliman‚ Genie Rose Chapter 1 Introduction Bouncing ball physics is an interesting subject of analysis‚ demonstrating several interesting dynamics principle related to acceleration. Almost everybody‚ at some point in their lives‚ has bounced a rubber ball against the wall or floor and observed its motion. Normally

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

ballet dancers you think of grace and beauty. While you watch a dancer dance you never think of the physics and mathematics behind their every move. Physics is described as a thing that is all about measurement‚ and that if you know the units of measurement that physics uses and how they work you will understand everything else you’ll learn about (Dennis and Moring 1). The textbook definition of physics is “the study of matter and energy and their relationships” (Zitzewitz 1). Ballet cannot be defined

Yoyo is a toy that everyone has played at some point in their lives. Yoyo is more than twenty five thousand years old. It is the second oldest toy‚ after dolls. The yoyo was first documented to be invented in Greece with wood‚ metal and terra cotta.2 .The disks were decorated with the pictures of their gods. The yoyo moved to the Orient around 1800. The yoyo was used as a weapon in Philippines. Their version was large with sharp edges and spikes attached to a twenty foot long rope for flinging at
