Car Velocity Lab Report

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.

Conclusion: The results of this lab were found through seemingly simple equations, basing all of your work off of data such as time and distance can become frustrating due to human inaccuracy, but the results show the height and initial velocity of the marble. The results are all reasonable compared with the beginning values that we collected during the lab, and even without calculations fit into the equation. The concept of projectile motion was the basis of this lab, focusing on using kinematic variables and equations to find the

As the car go down it looses its potential energy because it is not at the same height anymore. As it loses the potential energy it gains kinetic energy. Kinetic energy came along because of its high speed. The mathematical equation for this is initial kinetic energy plus initial potential energy plus external work equals final kinetic energy plus final potential energy. To find work the equation is force times distance. To find power the equation is work divided by time.

Next, the independent variable was the sail car and shed car. The speed acceleration was the dependent variable. The constants marble distance of photogate the angel of the track.

T= 40ms, I figured this by guessing cause I could not find any information on how to calculate. So I used the equation for t and plugged in different numbers until I got the 10ms that was already given in the table. t= T x 0/360= 40ms x 90/360= 0.01 x 10^-3= 10ms

If we measured in meters then a=4.9.) t is the time in seconds, v0 is the initial velocity of 30 feet per second, and s0 is the initial height or 4 feet. Thus we have:

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.

The sketch below shows the trajectory of a projectile propelled with an initial velocity V0 at an angle 8. Neglecting air resistance the horizontal range travelled is given

Kinetic energy is the energy of an object in motion. By doubling the speed of the car you are increasing its kinetic energy 4 times higher. If the kinetic energy is being

The mousetrap car, Versace, was tested multiple times to test how far it went. When constructing the car, the group members had different ideas, but all ideas were put into the construction of the car. The car was tested with CDs as wheels and then paper plates as wheels. Each time, when testing the car, the axle gearing had different measurements and distances. The group had finally gotten the best distance on the car. The group was also able to find the kinetic energy of the boat. Then the data from the tests were used to find the efficiency of the car. Overall, the car did very well.

Distance = 36 ft. x (0.3048 m. / 1 ft.) = 10.9728 m. is the answer.

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.

These are the two most crucial equations because now the jumper knows the angle of the ramp, the distance he needs to launch over, and the speed he needs to reach in order to clear the gap. He also knows how high he can expect himself launch, that way there are no surprises. The calculations are very important to the success of a motorcycle jump, but physics also play a role in the development of improvements.

The toy has uses two main energies, Kinetic and Potential. Potential energy is made by the pulling back of the car. Kinetic is made when after the car is

Step 8: We can now plot our values into the rearranged equation to figure out acceleration due to gravity ‘g’. (Eg. (4π2 x 43.70)/ 1.758 = 981.4 cm/s2)
