If you stopped the chair, the ball would continue in the same direction until you, another object, or friction stops it. When it is at a constant speed it is a balanced force just like it was before it started moving. If you put a restraint on the ball, like tying it to the chair, it would stop it from continuing to go. This is the reason we have seat belts in cars, so we don’t fly through the windshield if you stop quickly, because without that restraint, you’d continue to go right out of the car. And depending on how much you weigh, and how quickly the car stopped, you would probably go pretty far.
The slow oxidative fibers are set up to help with weaker amount of force but are very resistant to fatigue. Then the stronger motor units, although less resistant to fatigue are next, if more force is needed. 9. Restate your predictions that were correct and give data from your experiment that support them. Restate your predictions that were not correct and correct them, giving with supporting data from your experiment that supports your corrections.
The main causes of automatic transmission failure are due to normal wear, the loss of automatic transmission fluid, and abuse. One of the causes for automatic transmission failure is due to normal wear. An automatic transmission consists of many friction parts such as clutches and bands. Over time these clutches and bands will eventually wear out and will no longer be able to lock the parts together to produce a different gear ratio. When the friction plates are worn, the automatic transmission will begin to slip while trying to accelerate.
People may think they are still fully protected because the vehicle they are in has an airbag, but airbags are less effective and may be useless if the person is not wearing a seat belt (Marie). When the seat belt is not worn the body that is in the vehicle will not be in a position that will allow the person to receive the protection of an airbag, especially if they are not buckled into the seat. There is some belief that seat belts do not save lives and that they might do more harm then good. There are some rare instances when a seat belt has negatively impacted the chance of survival in a crash, but researches have shown that seat belts are the best chance of survival in a crash (DeLisa, 2010).Seat belts prevent any person from being ejected from a vehicle in high-speed accidents. “However, they work best when simple safety guidelines are followed.
Cell phones while Driving should be Illegalized Written by: Scenny Fryson Manoe/121211233005 Drivers should not be able to use their cell phones while driving because it is very dangerous for the driver, as well as others who are traveling along the same road. Cell phones are also a major distraction to the driver because it occupies one’s eyes and attention, which should be focused on the road. Everyday people die in car accidents because they use cell phones while driving. According to research cell phones are leading factors that cause accidents. Studies show that a cell phone put drivers at a four time greater risk of a crush.
If you're going in a specific direction, you will always go in that direction unless something happens to you. 2. “The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector.” The second law shows that if you apply the same amount of force on two objects which have different masses, you will get different accelerations. The bigger the mass of an object, the less effect the force applied has on it.
In a hypothetical scenario where Newton’s third law doesn’t exist, if you were to push against the wall your hand would go straight though as if nothing were there. This concept can be made more prominent if you imagine a vehicle impacting into a stationary object. Both objects would be severely damaged and the damage on both objects is a result of each other’s forces acting upon each other. However in this hypothetical scenario the vehicle would just pass through the stationary object. The formula can be applied to calculate the force generated when you sit on a chair, however thanks to newton’s third law of motion this is also the force that the chair acts upon you and prevents you from falling though you chair.
The major reason for accidents is speeding and smart cars would warn the drivers when they are going too fast and tell them to break. Traffic would also be greatly reduced because the driver would know which roads have heavy traffic and they would avoid them. 2. Describe three different types of IT used to make smart cars unique. • Hypovigilance system.
Once the investigation is complete they can begin to reconstruct the accident. During the reconstruction phase, physics is used to determine several aspects such as speed of the vehicles, their approximate positions at different times during the accident, and stopping distance (Glennon, 2001). If the cause of the accident is readily apparent then a reconstruction of the scene may not be necessary, such as with many of the multi-car pile-ups. Many of these accidents occur because of environmental factors such as fog, smoke, ice, or dust storms. Even though the main cause of the accident is environmental and out of the driver’s control, there are certainly things that could be done to minimize the effects.
This confirms inertia. The heading of a moving object to keep moving, or of a stationary object to remain at rest. Basically Newton’s first law; that a body stationary or moving with constant velocity will want to continue to do so, unless acted on by a force. Humans experience the Law of Inertia every time they drive in a car. When the driver makes a quick turn or stops suddenly, the passengers' bodies jolt and try to keep moving in the direction the car was just going. Because of inertia, it is very important that passengers in a car wear their seat belts while driving. In the case of an accident, seat belts provide an opposing force that can prevent a passenger from being thrown from the vehicle. Examples: An example of such a situation is the following: “Consider a stone placed in a wagon. If the wagon was travelling at constant speed in a straight line, the stone would stay in the same position in the wagon.
