So you see, Newton's 3rd law can explain your balloon powered car. air shoots out the back at high speed and the car moves forwards (more or less) at low speed. So the force used to accelerate all that air backwards has an opposite force on the balloon (reaction) which is tied to the car so pushes in the opposite direction. Well the air's coming out fast in the beginning but thats when the car is only just moving, it takes a while to speed up and it takes even longer if you have a heavy car. So you may be able to argue it shows that f is proportional to Mass x acceleration (but to be honest I think that would be stronging it a bit - balloons don't seem to give very constant thrust.
Here are just 5 reasons to drive slower: 1. Save gas. The best ways to save gas (besides driving less or driving a fuel-efficient vehicle) are to avoid excessive idling, more gradual accelerating and decelerating, and driving slower (see report on Edmunds.com). With gas prices so high these days, wasting gas by driving unnecessarily fast is something we can’t afford. 2.
How would you expect a truck with a cargo tank that has baffles to handle on the road?-There will be less front to back surge than there is in a tanker without baffles. 7.) Side to side surge can cause ______-Roll over. 8.) The amount of liquid to load into a tank depends on _______-The legal weight limits and the amount the liquid will expand in transit.
This proves Newton's First Law exists because if it weren't for the lever attached to the mousetraps trigger then the wheels would maintain a state of rest. The lever served as an outside force that effected the mouse trap car that was once at rest. If it weren't for the friction between the mousetrap car's wheels and the floor, the mousetrap car would continuously roll. The mousetrap car shows relevance to Newton's First Law because in each the lever, the wheels, and the string was a state of immobility. That state only changed when compromised by an outside force.
The Speed of Sound: | Sound travels at different speeds depending on what it is traveling through. Of the three mediums (gas, liquid, and solid) sound waves travel the slowest through gases, faster through liquids, and fastest through solids. Temperature also affects the speed of sound.Gases:The speed of sound depends upon the properties of the medium it is passing through. When we look at the properties of a gas, we see that only when molecules collide with each other can the condensations and rarefactions of a sound wave move about. So, it makes sense that the speed of sound has the same order of magnitude as the average molecular speed between collisions.
Using equations like F = MA, we can discover how many newtons (N) the mousetrap needs in order for the car to be moving at that rate. Another factor that is involved in building these mousetrap cars is the mass vs. acceleration. Using the equation F = MA, you can see that the smaller the mass is, the faster the acceleration is. This same concept works in reverse. The faster the acceleration is, the less mass it is.
This helps to stop accidents because it removes distractions from a p-plate driver so they can focus solely on driving. Another danger P-plate drivers face while on the roads is their driving speed. If a driver is going too fast, they are not able to stop fast enough or pay enough attention while driving, which can cause accidents. The current p-plate laws are effective in reducing accidents through a drivers speed by introducing laws which limit p-plate drivers to the speed of 90km/h, as well as not allowing p-plate drivers to drive turbo or supercharged engines or have modifications in their engines. These p-plate laws are affective in reducing accidents on the road, because they reduce p-plate drivers to a low speed as well as slow cars.
When shot is finished and athlete is landing they should land on the balls of their feet with feet shoulder width apart, knees slightly bent, and slightly bent over. B. Primary purpose of skill- The purpose of this skill is to get the ball in the basketball in your offensive hoop without the defense blocking your shot. C. Break movement down into phases- The basketball jump shot can be broken down into three phases; the first phase being the triple step phase, the second phase is the jumping phase, and the third phase being the landing phase. D. Classify the skill- The classification of the basketball jump shot is that it is not necessary to maintain erect posture because in both your triple threat position, and landing position slight trunk flexion is required.
Force Table Vectors I. Abstract: From chemical formulas and morality to vectors and forces equilibrium is a term used when the system comes to a complete balance on both sides and no changes occur. This is a critical point where balance is found in nature. In this lab equilibrium is calculated and found using different masses on a force table. A force table is a big compass with degrees marked off to form a circle, wheels are placed at certain points and a string is attached to 3 weights. These weights hang off the sides of the wheels and pull on the string at different angles, the objective is to find the point at which all the weights pull on each other so the center of the string is in the center of the force table.
This is called oscillating, when an object is undergoing periodic motion. To fully understand periodic motion we must first understand the concept of equilibrium and the two types. The first type is stable, when an object is in stable equilibrium any displacement of this object will result the object to try to restore itself to its original position. As stated in our lab manual, “For example, a weight hanging on a string is in stable equilibrium when it is at its lowest point. If the weight is pushed to one side, gravity will again try to pull it back to the lowest point.
