Kal Q Late It
100
If the density of an object is less than the density of a fluid.
What is the object will float?
100
The attractive force between two objects.
What is gravity?
100
The more mass, more particles, equals more this.
What is density?
100
Besides increasing the force, what you can do to increase the pressure.
What is decrease the area?
100
Density.
D= M/V?
200
The reason a hot air balloon is only temporarily less dense.
What is the air will cool, becoming more dense, and the balloon will sink?
200
Any substance that has no definite shape and is able to flow.
What is a fluid?
200
Which has a greater density - one piece of Hershey's chocolate, or the whole Hershey's chocolate bar.
What is neither - their densities are the same, both are made of chocolate.
200
The two types of fluid pressure.
What is air pressure and water pressure?
200
LxWxH
What is volume?
300
Buoyant force increases when you do this to an object in water.
What is begin to submerge it underwater - like a beach-ball?
300
Hydrometer.
What is an instrument used to measure the density of a material?
300
Step 3 in the displacement method.
What is subtract the volume of the water from the combined volume of the object and water?
300
The reason why there's less atmospheric pressure on the top of Mt. Everest.
What is there's less air pushing down on you?
300
Force divided by Area.
What is pressure?
400
Steel sinks, boats float, this is how.
What is the air space inside the boat decreases its density until it is less dense than water - and thus floats?
400
This is greater in salt water than in regular water.
What is buoyant force?
400
When you'd use the displacement method.
When the object is an irregular size/shape?
400
If the net force is going upward, the buoyant force is this.
What is greater than the weight/gravity?
400
A box exerts a force of 420N on a floor. The bottom of the box has an area of 0.7m(squared). This is the pressure exerted by the box on the floor.
What is 600 Pa?
500
The higher the pencil, the this the fluid is.
What is the denser the fluid?
500
Atmospheric Pressure.
What is the force exerted per unit area by air particles?
500
Besides the mass of the particles, this makes a huge difference in the density.
What is space between the particles?
500
You jumped into the pool. All the water that splashed out is equal to these two things.
1. What is your volume? (Displacement Method) 2. What is the buoyant force of your body. (Archimedes Principle)
500
The density of gold is 19.3g/cm(cubed). This is the volume of a 100g gold necklack.
What is 5.18 cm(cubed)?
