The Question: Does temperature affect the elasticity of a rubber band? Our Hypothesis: We thought that in hot water that it will be the most elastic. Simply because hot water make things stretchy and moveable like balsa wood. Material: 1. Three Cups 2. Nine rubber bands (should be the same) 3. Cold Water 4. Hot Water 5. Room Temperature Water 6. Two pencils (you will see why later) 7. Four Ice Cubes 8. Water that is sitting in an indoor location 9. Stop Watch 10. Ruler Experimental 1. Take one cup

Americans are hurt or killed in car accidents. Many factors can play into an accident. Road condition‚ mechanical failure‚ driver error‚ or simply an ’act of God’? Despite the countless reasons for a car accident‚ one factor is always present‚ no matter what the case: physics. Every accident that has ever occurred has involved physics. Using references found in the class text‚ in science journals‚ and on the Internet‚ I will prove this to you. Take‚ for example‚ two cars traveling in opposite directions

Toy cars have been played with by children for many years. Would one wonder the way a model or toy car rolls down a hill? One would think it would be because it has wheels‚ this is true but there is more to a car rolling downhill than it having wheels. Gravity is the force that is keeping all things on the ground. The heavier an object is the more gravity has an effect on its momentum. If you put a toy car on a downhill slope it will begin to roll because of gravity. The more the car weighs will

A rubber band in the dictionary is “a loop of stretchy rubber for holding things together.”. They are able to be stretched and using a method you can shoot a rubber band. One way to shoot it is to get your point finger and place it on the inside of the rubber band. Then it you get your other point finger and put it into the inside of the rubber and from the top. After that you pull your fingers back and that will stretch it. Lastly let go of the finger next to you and that will send the rubber

Effects of different liquids on the elasticity of a rubber band Luke lash and Charles baker Question: If we submerge rubber bands in different liquid substances‚ will its elasticity of the rubber bands increase? Hypothesis: If we use a more acidic substance like vinegar‚ then elasticity of the rubber band will increase. Background: We are conducting this experiment because although it has been done before‚ the substances that have been used before are generally ordinary. Others have used hot

Aim: To investigate the factors affecting the stretching of springs and rubber bands Scientific Knowledge: Before doing the experiment I came to the conclusion that this experiment relates to Hooke’s Law which states that extension is proportional to the load‚ meaning that if you stretch something with a steadily increasing force‚ then the length will increase steadily too. By looking at various sources I have also found out that if a mass m on a spring is displaced from the equilibrium position

Year 11 Preliminary Assignment #2 – Physics Electricity in the Home Aim: Will the current (Amps) affect the time it takes for a slot car to complete a lap of the track? Planning the investigation: 1. What do you know about the topic from personal experience? From playing with slot cars and building tracks even before I embarked on the physics course‚ I’d always realised the relationship between the trigger and the speed of the cars. In the investigation‚ I hope to use a more scientific method

The Physics behind Car Safety Systems By changing an object’s momentum‚ we are able to move it either faster or slower‚ and eventually to a halt‚ depending on the amount‚ direction‚ and magnitude of the force that acts upon the object. By applying this aspect on a car’s safety systems‚ we are able to either reduce the risks of injuries as the results of a crash‚ or to avoid a crash completely. It is with this principle that seatbelts‚ crumple zones‚ air bags‚ and braking systems‚ among other features

Physics of Car Crashes: Airbags Car crashes are a massive cause of death in the world‚ especially in Bangladesh. Every year‚ a lot of people die or get injured from car crashes. As car crashes are destructive for human life‚ we must take scientific measures to reduce the amount of danger in the crashes. There are different types of scientific measures that are taken all over the world‚ one of the most effective ones are airbags. An airbag’s goal is to slow down a passengers forward motion as

Motion of the Cars In this part of the experiment‚ we are trying to figure out how fast each of the cars are moving using our own measurements. We are also asked to make a mathematical equation that describes the motion. What we plan to do is use 2 meter long meter stick to measure the distance of the cars and record the position at each time interval. After that an average velocity can be found. After we used the average velocity‚ we were able to put it into the equation of a line formula and
