Transcript: Bessy- My Balloon Car Speed per Meter Graph! Acceleration Graph! Distance- The length of a path between two points. Our goal for the balloon car lab/race was to get our car to go five meters. My car only went four meters. Speed- The ratio of the distance an object travels to the amount of time the object moves. Formula: distance/time=v (speed) We had to find the speed of our cars. To be more exact, we found the instantaneous speed. Instantaneous speed- The speed is measured at a particular instant. For example, every time our balloon car crossed one of the meter marks the person timing the car stopped their timer. We then used that time and the distance to find the instantaneous speed. Average speed- Average speed is computed for the entire duration of a trip. Formula: avg. distance/avg. time Not only did we have to find the speed per meter for each trial, but we also had to find the average speed for each trial. Acceleration and Instantaneous Acceleration: Acceleration- the rate at which velocity changes. Instantaneous Acceleration- how fast a velocity is changing at a specfic time. We had to find the acceleration of our car per meter. In order to find the acceleration we already had to know the speed because the formula for acceleration is change in velocity divided by total time (vf-vi/t). I had positive acceleration, but I also had negative acceleration. Displacement- the direction from the starting point and the length of a straight line from the starting point to the ending point. When a ball bounces off a wall and comes back some you can find displacment. Sure, it may have went a total of 10 feet but now it's only 5 feet away from where it started. Vector additon- combining of vector magnitudes and direction. Resultant vector- the vector sum of two or more vectors. Frame of Reference- a system of objects that are not moving with respect to one another. Example: The people sitting at the different meters timing the cars could be considered the frame of reference. Linear Graph- display data from straight-line parts. Vector- a quantity that has magnitude and direction. Constant Acceleration- a steady change in velocity; the velocity of the object changes by the same amount. Example: This didn't relate to any of our balloon cars; I know it didn't relate to mine. Velocity- speed and direction in which an object is moving. Example: You could have found the velocity for our balloon cars; they went in one direction for the most part and we already had found the speed. Nonlinear graph- curve connects the plotted points (data). Relative Motion- movement in relation to a frame of reference. Example: The cars being pushed by the balloon.

Transcript: How did Newton's three laws effect our car? Our car travelled 327 cm. It did it in 2 seconds. Our overall score is 76. Newton's First Law The second law of motion states that force is equal to mass multiplied by acceleration. We added extra weight to our car in order to achieve more force. Our car as a whole utilized this law becasue all the car's parts attributed to its mass. The first model of our car had a straw that ran underneath the bottom of the car. The balloon was attached to the bent part of the straw and was taped to the top of the car. We thought this would give the car more stability. But it ended up letting the air out too slow, this caued for a very smal amount of force to act on the car, also causing the car to never move. To fix this we attached a balloon to the top of the car without any straw. This made it so there would be more force and more acceleration. Objects at rest or at a constant will remain like this untill an outside force acts upon it. This law is often called the law of inertia. Our car would have remained at rest if the air coming out of the balloon didn't propell the car forward. The forces of friction and air resistance also acted on the car causing it to slow down and eventually stop. The balloon made use of this law because it applied the force that caused the car to move. Balloon Car By: Danny Ehrlich Tim Kennedy car side view Every action has an equal and/or opposite reaction. This law is applied to our car because the force of the air coming out of the balloon causes the car to move. This law specificaly pertains to the balloon on our car.
