The acceleration due to gravity on or close to the earth's surface is always g, (981cm/s/s). An object can be restricted from achieving this in many ways eg putting it on a table top. Nobody asks why the acceleration due to gravity is zero on table tops. Water also restricts acceleration due to viscosity, which, as for parachutes in air, will be velocity dependent. So the short answer is, in water the object is in a restricting environment, unlike in free fall where the acceleration will be g.
What else can I help you with?
What keeps water in a rotating bucket from falling out?
Centripetal force. The water wants to fall out due to gravity, but the speed of the rotating bucket cancels it out, creating an inward acceleration.. It is the same as why you don't fall out of an upside sown roller coaster. The speed has to such to cancel out gravity acceleration, where velocity squared divided by the radius of the rotating circle is the acceleration of gravity
What is the downward force on water?
The downward force on water is due to gravity, which pulls the water downward towards the Earth's center. This force is known as the weight of the water and is determined by the mass of the water and the acceleration due to gravity.
How do you calculate pressure underwater and what factors affect it?
Pressure underwater is calculated by multiplying the depth of the water by the density of the fluid and the acceleration due to gravity. The formula is pressure depth x density x gravity. Factors that affect pressure underwater include the depth of the water, the density of the fluid, and the acceleration due to gravity.
What is value of gravity on earth?
weight = Force of gravity Force= Mass x acceleration so Force of gravity = Mass x -9.81 that's -9.81 is acceleration in relation to the force on earth. and its negative because gravity pulls things down in a negative direction towards earth. mass= weight in kg acceleration= -9.81 m/s^2 on earth force = is how much gravity pulls on the object and its in Newton's. how this is what you wanted
Why a boat floats using the words mass and volume?
The mass of the boat multiplied by the acceleration due to gravity is less than the mass of the water displaced by the boat multiplied by the force of gravity. Archimedes' principle applies to the weights (not mass) and so it is important that the acceleration due to gravity is included in the answer.
What is the acceleration of a full bottle of water dropped from adesk?
The acceleration of a bottle of water dropped from a desk is approximately 9.81 m/s^2, which is the acceleration due to gravity. This means that the bottle's speed increases by 9.81 meters per second every second it falls.
What happens when gravity pulls water down a slope?
The water runs down hill. That's why all rivers lead to the sea.
In a rooftop water gravity tank what is the gravity pressure?
The gravity pressure in a rooftop water gravity tank is determined by the height of the water column above the outlet. This pressure is calculated using the formula P = ρgh, where P is the pressure, ρ is the density of water, g is the acceleration due to gravity, and h is the height of the water column.
How many newtons are in 2570mL of water?
The mass of 2570mL of water is 2570g. To convert this to Newtons, we use the formula Force = mass x acceleration due to gravity. The acceleration due to gravity is approximately 9.81 m/s^2. Therefore, the force exerted by 2570mL of water is 2570g x 9.81 m/s^2 = 25,202.7 N.
How is underwater training similar to the experience that astronsouts will have in space?
water is similar to outer space because it has little gravity so astronomers use it to practice in it to get ready for outer space.
How do orbiters counteract the massive pull of a large planets gravity p?
centripetal acceleration counters the acceleration due to gravity creating an equilibrium. the EXACT same way water wont fall out of the bucket if you spin it fast enough. Gravity is also a field and decays as the distance between the two objects increases. GMm/r^2
How do you calculate weight in air when we know weight in water and water displaced?
To calculate weight in air when we know weight in water and water displaced, you can use the principle of buoyancy. First, subtract the weight in water from the true weight to find the buoyant force acting on the object. Then, divide the buoyant force by the acceleration due to gravity to get the volume of water displaced. Finally, use this volume to find the weight of the object in air by multiplying it by the density of water and acceleration due to gravity.
