When constructing the car, the goal was to make the car as sturdy as possible in order for the car to travel a great distance in a short amount of time. To do this, we researched various ways to create a mousetrap car. Additionally, we incorporated our own ideas to enhance the construction after trial and error. First, our team gathered all of the necessary materials that we would need to construct the car. These materials included one mousetrap, cardboard pieces, six balloons, four eye hooks,…
Bouncy balls bounce because the material of the ball is extremely elastic and can convert kinetic energy from falling into potential energy and back into kinetic energy again with little loss of momentum. They are used in many classrooms because they can easily demonstrate conservation of momentum through a highly elastic collision. Like many things made out of rubber, bouncy balls have very high elasticity, meaning they rapidly return to their resting state after being stretched or squashed. If…
By finding the area underneath the velocity versus time graph and by adding up all the displacement intervals gave values near each other. This means that there are two ways to calculate displacement using a velocity versus time graph. Experimental Uncertanties There were several experimental uncertanties accountered in the accelerated motion lab. Firstly, the presence of air resistance. As the object traveled down the ramp increasing its velocity, air resistance increased which affected the…
by an outside force. This law applies to gymnastics when a gymnast is flipping through the air they will not stop flipping until they either hit the ground or change their body position. Newton's second law states that the net force acting on an object will cause it to accelerate (F=ma). Newton's second law applies to gymnastics because male gymnasts are usually more muscular than female gymnasts so the tend to have more mass. This means that they will have to apply more force than female…
The acceleration of the object will increase as the force of the object increases. In this case the propelling force is thrust. In order to increase thrust, the water must be expelled from the rocket at a fast rate. Secondly as the mass decreases, acceleration will increase due to the inverse proportions and because of the increasing…
Unit Three: Energy Our universe is made up of matter and energy. Matter is made up of anything that has mass and takes up space where energy allows the ability to do work or have the ability to move or elicit change in matter. In other words, energy is a property of objects which can be transferred to other independent objects or be converted into different forms. It is described as “a system to perform work.” We have two different types of energy; kinetic and potential energy. Kinetic energy is…
Background Knowledge The question for this experiment is, Does the angle of an airplane wing affect the average rate of descent of the plane while gliding? So, the thing that is being tested is if the angle of an airplane wing, which determines the average rate of descent. In this experiment, the average rate of descent will be found by dividing the distance the plane traveled by the time it took the plane to land. First, how planes fly needs to be understood. Airplanes fly because the wings…
Paintball Vs. Airsoft There are very few situations where you have to worry about being shot. The one most would think of would be in the field of combat in a different country. Most people don’t realize though that they can get the same adrenaline rush in a safe environment. There are actually two popular ways; Airsoft and paintball. Paintball and Airsoft are both ways to simulate the feelings of live combat and have similar features. In order to begin feeling the adrenaline rush flow…
The same rules apply, gravity is pushing the marcher down and the ground is pushing back. Same with friction, friction keeps the movement steady and momentum determining how fast and how far the movement will take the marcher. This time there is force. As stated, instead of a lift there is a push of the foot giving more momentum to the movement. This can make the marcher go farther or faster but it does depend on how much push you give. You will receive an equal and opposite push back from the…
The force of gravity is a force which means that any work done by it does not change the mechanical energy of the carts. The normal force of the track pushing up on the cars is an external…
