Acceleration Due to Gravity Conducted on October 6th‚ 2014 Objective: The object of the experiment is to determine whether or not objects fall freely at the same rate and speed. Measure and calculate the time in which it takes random objects to hit the ground from a certain height and determine if the objects have the same rate of motion or not. Materials: 1. Meter Stick 2. Stopwatch 3. Wallet 4. Quarter 5. Tape 6. Hot sauce packet from Chinese food delivery 7. Container of wipes

The weight equation which is weight (W) = mass (M) x gravitational acceleration (A) which is 9.8 meters per square second on the surface of the earth. The gravitational acceleration decreases with the square of the distance from the center of the earth. If the object were falling in a vacuum‚ this would be the only force acting on the object. But in the atmosphere‚ the motion of a falling object is opposed by the air resistance or drag. The drag equation tells us that drag is equal to a

Introduction The projects objective is to design a bridge spanning across the Murrumbidgee River located near Gundagai. Through the use of hydrological data and hydraulic analysis we will determine the required height of the bridge corresponding to a specific frequency of flood. To design a bridge capable of spanning the Murrumbidgee River and flood plain will require hydrological analysis which takes into account all upstream data that is required for the catchment area of the river that will

having dimples on the golf ball reduce drag? Firstly we have to look at the aerodynamics around golf balls‚ since the only force that can slow down a golf ball while in mid-air is the air flowing around the surface of it. We call these resistive forces drag forces‚ and there are two kinds which inevitably slow down spherical golf balls; pressure drag and skin friction drag. Skin friction drag is the shear forces on the sphere from the air molecules. Pressure drag is a resistive force caused by turbulent

1908. Unlike other designs‚ the dimple proved to be the most aerodynamically efficient. Dimpled balls fly farther than non-dimpled balls due to the combination of two effects. There is drag‚ which is the force acting opposite to the object to slow it down‚ lift which is the force acting at a right angle to drag and generally upwards‚ and gravity. How is lift created? Newton’s third law states that for every action there is an equal and opposite reaction. The ball when spins exerts a force

in me falling off of a lot of waves. There are two biomechanical principles that help explain propulsive forces produced by a surfer when paddling through the water‚ these include: * Drag force * Lift force Drag force: Definition: Drag force is due to pressure difference (Amezdroz‚ et al‚. 2010). Drag force is used to propel a surfer in water. “As the hand is pulled back in the water‚ the water then flows or travels past the hand and becomes turbulent at the back of the hand. This fast

it is viewed as natural. The culture of drag serves as a testament to this. Drag culture points out that gender is in fact a form of impersonation‚ as the purpose of the culture is to imitate women (Butler‚ 1993). Butler states that this imitation of women corroborates the notion gaining cultural acceptance only requires some cosmetic changes as well as mannerism‚ which are not inherent qualities that women have from birth (Butler‚ 1993). Ultimately‚ drag goes against the norms people accept as the
