For a liquid ... is uniform throughout, and for a gas ... can vary density 2 of 15 ... = Height of column of liquid x Density of liquid x Gravitational Field Strength pressure 3 of 15 Objects in fluids experience ... upthrust 4 of 15 The upthrust is equal to the weight of the fluid ... displaced 5 of 15 An object ... if the weight=upthrust floats 6 of 15 ... pressure decreases with height- Created on a surface by air molecules colliding with the surface atmospheric 7 of 15 ... is how far something travels. It's a scalar quantity so doesn't have a direction distance 8 of 15 ... is a vector quantity. It measures distance and direction in a straight line from an objects starting point to it's finish point displacement 9 of 15 ... and ... are both measures of how fast you are going, but ... is scalar and ... is vector Speed Velocity 10 of 15 ... is just how fast you are going with no regard to direction speed 11 of 15 ... is speed in a given direction velocity 12 of 15 You can travel at a ... with changing velocity.- Happens when you change direction at same speed constant speed 13 of 15 ... = speed x time distance travelled 14 of 15 Typical Speeds for everyday objects- 1.5 m/s Person Walking 15 of 15
