It is true. In a Six Flags Amusement park in Chicago‚ a ride suitingly named the “Goliath” is a rollercoaster made from wood and steel. On one of the hills‚ the inertia is greater than the negative acceleration of gravity‚ creating an intense feeling of weightlessness. These rides must be propelled in some way. The most common way is through the use of large hills. Using gravity to accelerate the car down the large hills is a way that engineers can make

Carousel: Centripetal Force Imagine spinning a ball on a string around you. The ball is traveling in a circular path. But Newton’s first law states that an object in motion stays in motion and that motion is in a straight path‚ not a circular path. Since the ball is traveling in a circular path‚ an outside force must be acting on the ball - that force is the string. The string is pulling the ball back toward you‚ acting as the centripetal force. Centripetal means "center-seeking" and

Chapter 6 Describe the “coin and feather” experiment and state what the observation shows. (5M) Put a coin and a small paper disc in a glass tube (1M) Use a vacuum pump to remove the air from the tube (1M) Hold the tube vertically then invert it quickly. (1M) The coin and the paper disc fall at the same rate (1M) The experiment shows that objects with different masses fall at the same rate when there is no air resistance. (1M) How can you find the height of a building if you are given

(a) downwards with a uniform acceleration of 5m/s2 . (a) upwards with a uniform acceleration of 5m/s2. What would be the readings in each case? (d)what would be the reading if lift mechanism failed and it hurtled down freely under gravity? 2. A shell of mass 0.2kg is fired by a gun of mass 100kg. If

such as inertia‚ gravitation‚ and centripetal forces and utilizes different types of energies such as potential and kinetic energy. Physics is what makes roller coasters safe and effective. It is not only the high speed of the trains of a roller coaster that makes the ride so thrilling but the acceleration of the train and the occasional feeling of weightlessness. At various times‚ roller coasters‚ or more specifically the trains of these‚ undergo acceleration‚ which is defined as the rate of change

While riding the wheel of fate while it is continuously moving I felt the greatest acceleration at the bottom of the Ferris wheel. We don’t experience a great acceleration at the top because our weight pushes us toward the center so it cancels some forces that will give a greater acceleration while when we are at the bottom of the wheel both rotation and weight are acting on us so it results to a greater acceleration. As I observed the position of the horizon varies with my position like when I’m at
