Friction And Toy Cars

To create a mousetrap car and measure its performance. We will also see where force and energy is impacting on the performance, for example friction will impact on the cars performance as it generates heat and slows to car down thus meaning that the car may not travel as far as it should. Another force that is demonstrated in testing of the car kinetic energy, without kinetic energy the car would not travel at all.

NASCAR is a sport of racing that most people try to say it’s not a sport just because they just make left turns only which is false, because the also make left and right turns on two scheduled events that they make twice a year. Many people don’t understand the physics of a NASCAR car of how they run and how they are developed to run as fast as they go and how they handling speeds from 55 to 200+MPH.The physics of NASCAR also is developed on wind tunnels and simulation different race tracks as well. These cars have a lot of key roles that science is important for these, for example a car body has to be so smooth that the air flow goes over the car in areas that are very important so the car won’t have some drag but has some drag so that the

In this lab, we applied the concepts of velocity,force, acceleration, time, and distance in order to calculate which trial had a higher velocity. We also learned the relationship between each of the factors and how altering one plays a role in the other factors. For example, if we were to apply more force the velocity of the cart would increase, as well as the amount of time it took for the cart to go down the

The two types of friction of the mousetrap car are rolling friction and static friction are the two types of friction that may affect the performance of the mousetrap car. The problem of the friction did I encounter and how do you solve them one types of friction i encounter was the static friction I had to take off some glue from the stick that had my wheels and to open eye screws. The factor did take into account to decide the number of wheels you decide to chose for the mousetrap car I saw a video of a car that had 4 wheels and it ran really fast, so I thought a 4 wheeled car would run fast or at least the four meters. What kind of wheels did I use in each axles I use tires as my wheels on each axles. I think the affects on using big wheels

The purpose of this laboratory experiment is to construct a mousetrap vehicle. The vehicle needed to go travel five meters. My partner and I build a mousetrap car that obtain a two-axle vehicle with four CDs making the produce optimum acceleration and travel.

We were given groups to design and make a mousetrap powered car that will roll as far as possible. This will be measured and be put into a graph. We will make three modifications to our mousetrap car over the course of the experiment. We have a variety of different materials, including plastic, wooden wheels and a dowel, screws, mousetrap, blue tack and a piece of string. Forces were acting in a negative way and a positive way on the car. Gravity was pulling the car down to the ground. Uplift was pushing up upon the car against gravity. Drag was also known as friction, holding back the car while it was moving. Thrust was in the cars favour, pushing forward against the force drag. There were also many forms of energy being used and being wasted like heat and sound energy. Potential energy was stored in the mousetrap, propelling itself forward. Kinetic energy was also demonstrated when the car started to roll.

When the mousetrap car moves down the track, the speed of the mousetrap car decreases, therefore my hypothesis was supported. At 1 second, the mousetrap car was traveling at a speed of 3.2 m/s. At 2 seconds, the mousetrap car was traveling at a speed of 2.35 m/s. At 3 seconds, the mousetrap car was traveling at a speed of 1.53 m/s. At 4 seconds, the mousetrap car was moving at a speed of 1.2 m/s. At 5 seconds, the mousetrap car was traveling at a speed of .98m/s. “A car will eventually come to a stop if just allowed to roll as the friction between the road surface and the wheels causes friction that causes the vehicle to stop,”(Examples of Rolling Friction). The evidence supports the claim because the wheels of the mousetrap car are moving

The author, a physicist, caught a NASCAR race on television and wondered those same things. In The Physics of NASCAR, Leslie-Pelecky explores the science

The balloon powered race car will be powered by the balloon. The balloon will be blown into and the straw will be the source of the air going into the balloon and then pinched so there is no release of air, then release the air, measure the distance and speed of the car when air is released. This uses the three Newton laws and they are when an object is at rest it stays at rest and an object is in motion it stays in motion in a straight line at constant speed unless acted upon by an unbalanced force, the next is the acceleration of an object depends on the mass of the object and the force applied, the last is every action there is an equal and opposite reaction.

The more weights added to the car the faster the car goes. Our mass hypothesis, if the weight of the hot wheel decreases then the speed of the hot wheel increases. Our hypothesis is incorrect, we said the more weights you add the speed of the hot wheel will decrease, the data my group collected tells us the opposite the more weights you add the speed of the hot wheel will increase. Our hypothesis on road surface was, if the roughness of the road increases then the speed of the car decreases. This hypothesis was also incorrect, our data tells us that changing the road surface increased speed instead of decreasing it. Changing road surface and weight increased the speed of the hot wheel car. Our data we collected could have been affected by not placing the car at the same spot every time or not stopping the stopwatch fast enough. Our procedures did change during testing, we were going to stop the stopwatch once the back wheels were at the end of the track, we changed that because we wanted accurate times so we extended the stopping length 40 cm. In conclusion, if I were to do this experiment again, I would make sure I stop the stopwatch on

I utilized the coefficient of friction values based on skid testing conducted by the Institute of Police Technology and Management, (IPTM). IPTM testing, indicates a coefficient of friction of .90 - 1.50 for a vehicle furrowing.

The main objective of this lab was to measure the friction force it takes to start moving a weighted block across a table, and as it continued to move. This force was tested experimentally in three separate ways. The force was then solved graphically and mathematically through six different runs per method. TALK ABOUT RESULTS HERE.

Friction allows the car’s wheels to spin across the floor without just sliding across the floor. Friction is also present in the gear box of the toy car. Friction is present because the gears have to rotate against each other in order for the toy car to obtain potential energy. The toy car only produces rolling friction, which is present when the wheels rotate against the floor. Rolling also appears in the gearbox. Friction while not energy affects the energy in the toy car in two ways. Friction causes kinetic energy to be lost while the car is moving. Kinetic energy is lost when the wheels rotate against the floor because the wheels are using kinetic energy to move. The energy is then lost when because of rolling friction heat is produced. In a shorter sense the wheels because of friction convert some of the kinetic energy into thermal energy (heat). Energy is also lost when the gears in the gear box rotate against each other. Some energy would be lost because of the friction of the gears some potential energy would be converted to thermal energy affect making less potential energy available. While friction causes a loss to energy, rolling friction allows less work to be able to overcome friction (“About Friction”, 2003). Friction while not energy plays a part in both energies that affect the toy car.

     Acceleration and Speed are obviously the two defining characteristics of a fast car. Newton’s three laws of motion are an essential part in determining how fast a
