aspect differ greatly from one object to the next. I observed that when air resistance is considered, the lighter an object is or if its diameter is small, the object tends to travel farther than its heavier and wider counterparts. This is due to the forces acting on the object like gravity. Uncertainty I found that there was hardly any uncertainty in the results of the simulation without air resistance, however, the results of the test…

used. There are four forces acts on a train. One of them is its weight which balanced by the typical reaction of the tracks. The third one is the thrust force produced by the locomotives which move the train forward, and the fourth one is the combination of air resistance and the rolling friction between wheels and the railway tracks. There is another force called Centrifugal force act on a train when it takes turns. This force tends the train to run straight, but this force is overcome by the…

of the force of gravity. Gravity is a force of attraction between two objects, that is highly affected by size and proximity (gravity will have a stronger pull if the object are larger and close together). Gravity also differs from the mass of an object the more mass an object has the more gravity it will exert on the objects around it. When looking at really large masses, like the earth the gravitational pull becomes much greater because of its large mass. The earth's gravitational force pulls…

Lesson 1: Investigating physical forces. Learning objectives: Students will be able to investigate and explain how applying or removing physical forces of varying intensity can cause objects in their environment to move, stop moving, stay at rest, or change direction. Content: Wind/ physical force:Collected from http://handmadekidsart.com/wind-power-car-races/ -The surface area contacting the wind force will affect the movement. -The high speed of the wind will allow the object to move faster.…

all started when in 1979 Micheal Porter brought another four competitive forces in “How Competitive Forces Shape the Strategy”. One of the leading electronics companies in todays worlds that features its strategy based on the Five forces is Apple. The main concern will be how does these forces apply in such a big company as Apple and how do they help to determinate the strategy for the future. Michael Porters’s five forces can easily provide us with information such as which factors will have a…

FORCE AND STATIC EQUILIBRIUM Introduction The research is to be made on the most important concepts of the civil engineering which are force and static equilibrium. These concepts are very important for the engineering point of view. The force can be considered as the element which moves or tries to move and stops or tries to stop the body in motion. So whenever there is a force applied on an object it changes its inertia and causes to changes its state of rest or motion. The structures should…

Diagram 1.6: Diagram showing tension force in the string (from 0 cm increasing in 1 cm until a displacement of 15 cm has been attained) This diagram shows the manner in which the tension force applied to the string was calculated. Starting at 0 centimeters, forces were provided in the string such that the string would extend one additional centimeter from the previous measurement. Using the Capstone® software, the force applied to the string was calculated at the given horizontal…

flight there are four basic components; thrust, drag, lift, and weight. Newton’s laws and The Bernoulli Principle are the explanation of how everything works. Balance of force is a very important part of it. If the upward force is greater than the gravitational force imposed on an object, the object will go up. If the gravitational force is greater, then the object will go down or remain on the ground. World War I was the first time that airplanes were used on a large scale. At the start of…

Using physics, we can calculate the mass of a bolt fired from a blaster used in Star Wars: The Force Awakens. First of all, we know that these bolts are not lasers based on two facts: they can be seen from the side and they do not travel at the speed of light. Thus, from there, we have to find their velocity. Rhett Allain calculated that to be about 35 m/s. He did this by finding distance and time of various bolts fired throughout the series, dividing the two measurements, and averaging out all…

Natural Forces Affecting the Driver In one or more complete sentences, explain how natural laws apply to the following scenarios: 1. How does inertia affect a person who is not wearing a seat-belt during a collision? The prison will continue going forward at the same speed as the car was before the collision until something stops them. 2. How does kinetic energy affect the stopping distance of a vehicle traveling at 30 mph compared to the same vehicle traveling at 60 mph? There is 2 twice the…
