Centrifugal Force- When a car moves along a curved path it’s velocity is changing. Centrifugal force is the that causes this. It directly means center seeking force. 6. Centripetal Force- This is a force that pulls from the center of the car when in a circular motion. It’s the opposite of centrifugal force and does increase with acceleration.

1. The drawing shows three containers filled to the same height with the same fluid. In which container‚ if any‚ is the pressure at the bottom greatest? (a) Container A‚ because its bottom has the greatest surface area. (b) All three containers have the same pressure at the bottom. (c) Container A‚ because it has the greatest volume of fluid. (d) Container B‚ because it has the least volume of fluid. (e) Container C‚ because its bottom has the least surface area. 2. Three solid objects are floating

due to gravity‚ g the acceleration due to gravity‚ G the Universal Gravitational Constant (6.67x10-11 N.m2/kg2)‚ m the mass and rthe distance between two objects. Then F = G m1 m2 / r2 Acceleration due to gravity outside the Earth It can be shown that the acceleration due to gravity outside of a spherical shell of uniform density is the same as it would be if the entire mass of the shell were to be concentrated at its center. Using this we can express the acceleration due to gravity (g’) at

My Solar System Name Period Introduction: Every physics student has had a lot of experience with the force of gravity. Unfortunately‚ this experience is limited to the interaction between a very large object‚ the Earth‚ and much smaller objects that are very close to it. This is a very limited range of the possibilities. Software simulations of gravity allow physics students to explore a variety of other gravitational interactions between objects. These activities are designed to be used

Rise over run. 5. What is acceleration?-increase in the rate of speed of an object or the rate of change of velocity per unit of time. 6. What is the area under the velocity time graph?-the displacement during the stated time interval. 7. What is the slope of the velocity time graph? The level of acceleration. 8. What is the y intercept of the velocity time graph?-the initial velocity or 0m/s. 9. What is the area under the acceleration time graph? - The speed. 10

Many aspects of science were involved with the making of Europa Report. This movie included aspects of real science to make in more accurate even though the story of Europa One is completely science fiction. It included ways to deal with gravity on the ship‚ ways to get the ship to Europa‚ and a drill that digs through the ice of Europa. Gravity is a huge issue when it comes to space flight. Europa Report dealt with it in two ways. Cordero decided to show the astronauts in this movie actually working

no other! Experience an inertia jerk as you lurch forward and up a larger-than-life hill at a constant speed. Anxiety is at its highest as well as potential energy when you reach the top of the 350 foot tall hill. As you fly down the hill‚ your acceleration rate is at an all time high. All of a sudden‚ you realize there’s a shark in the water below with its jaws wide open ready to swallow you up! You scream in terror as the tracks shift upwards‚ narrowly saving you from becoming a shark snack! You

“A roller coaster is considered any elevated track with curves and rises‚ carrying passengers in open‚ rolling cars for entertainment” (5). Today’s roller coasters appear to be tons of tubular metal intertwined around itself‚ but regardless of how big‚ fast‚ or gravity defying they are‚ they all use the same natural force – gravity. The more twisting‚ turning‚ flipping‚ and the faster a roller coaster goes‚ the more the coaster depends on the law of physics‚ not mechanics‚ to keep it moving. There
