Escape velocity

Plato’s Cave Allegory in City of Ember The secrets of the real world lie buried underground, hidden in a secret box; a box that only Lena has access to. In this movie, City of Ember, Lena and Dune uncover a round map that may lead them out of their underground life. It is during their trek to find the truth that I discover many similarities between the plot and Plato’s metaphysical views. There are many instances where the theory of forms is present. In addition to a metaphysical comparison,…

Introduction: Every company wants to improve the quality of their product which in turn will increase the market potential of their product. Food companies are also among those companies those have always tried to develop new ways to provide fresh and healthy foods to their customers. In this process, they have to face some difficulties. These difficulties usually happen in the sorting phase of foods. Everyone knows after the passage of time, every food item loses its freshness. As a result, it…

because projectiles have a constant velocity, resulting in no horizontal acceleration. The y component of acceleration is a constant -9.8 m/s2 in relation to the gravitational force acting on the projectile. Why does the x component of velocity remain constant? The x component of velocity remains constant because since the horizontal acceleration is 0, then the x component of velocity (horizontal velocity) must be constant. The expression for horizontal velocity at any time is vx=c, and as you…

At (a), the surface is not inclined. When a vehicle moves around a bend or a corner on a flat road, it is moving in circular path. Therefore, it will experience centripetal acceleration and there must be an external force causing centripetal acceleration. As shown in the diagram, the only thing in contact with the car is the road, which is between the tyres of the vehicle and the surface of the road. Therefore, we can know that the frictional force exerted between the tyres and the road directed…

INTRODUCTION Can the magnitude of gravity be found by measuring the period in relation to the length of the string of an oscillating pendulum? The aim with this lab was for us to gain a greater understanding in the area of oscillations and simple harmonic motion. Also to determine if the use of a pendulum is a good strategy for measuring the gravity. I found this experiment to be very interesting since I’ve seen and used pendulums a lot before, but I have never really reflected on why they…

concerned about his maximum height, horizontal and vertical displacement and the speed required to perform a perfect jump with a double axel. A figure skater’s trajectory can be determined by the initial takeoff angle of the ice skate’s blade, initial velocity, and the initial height of the takeoff. The peak of the figure skater’s vertical displacement is also known as the figure skater’s maximum value due…

hill. As a consequence, they will experience the feeling of weightlessness, free fall, huge amounts of kinetic energy, and air resistance. The drop gives you an instantaneous speed of 56 miles per hour. This is also where you reach your terminal velocity. As you are falling, you will feel as if you are only being held down by gravity, which in fact, you are.…

A ball, and a feather dropped at the same height will hit the ground at the same time when placed in a vacuum space. This is because acceleration of motion is the same for both object, and in this experiment, we are going to calculate accelerated motion using inclined planes. In this experiment, we will see whether “distance traveled is directly proportional to the square of the time”, and “if speed of a falling object depend only on the height from which it falls”. This experiment will give us…

Introduction In this lab, we are measuring the ranges R of the ball as the function of the heights, H, that the ball is dropped from. I will use these data to determined the relationship between the height and the range. Procedure We divided this experiment into three parts. In the part one, the object was to observe the scatter in data. To do this, we set up the equipment: the bounce plate is 20 cm above the table ,the drop plate 20 cm above the bounce plate, a piece of carbon paper…

Renatta Oyles car driving down 84th street like she is has a velocity of a leftward direction and a leftward direction for acceleration. Velocity is defined as the speed of an object that is going in a certain direction. In this case her velocity is in a leftward direction because she is starting on the right and her car is moving to the left. She is starting on the right because in the diagram is shows that she was stopped on the right and those are the first dots in the diagram because she…
