Cards (20)
- What are we calculating in this video?
- What primarily causes pressure on an object submerged in water?
- What happens to pressure as an object moves deeper in water?
- What determines the pressure in a liquid?
- What is the formula for pressure in a liquid?
- If the height of the liquid column is 20 meters, density is 1000 kg/m³, and gravitational strength is 9.8 m/s², what is the pressure?
- What is the pressure at a depth of 90 meters with the same density and gravitational strength?
- How do you calculate the change in pressure when moving from 20 meters to 90 meters?
- What is the change in pressure when moving from 20 meters to 90 meters?
- What is up thrust in relation to submerged objects?
- Why does a submerged box experience a larger upward force at the bottom?
- What determines whether an object floats or sinks?
- What happens if the weight of an object is larger than the up thrust?
- What happens if the up thrust is larger than the object's weight?
- How can we determine if an object will float without calculating up thrust and weight?
- If a rock is denser than water, what will happen?
- If an apple is less dense than water, what will happen?
- What factors affect the pressure in a liquid?
- What are the conditions for an object to float or sink?
- What is the relationship between density and buoyancy?
