Is kicking a ball or throwing a ball considered applied force? Explain.
Answer:
Kicking a ball involves you applying a force because you are pushing it with your foot and that makes it fly up. Once you shoot something into the air, the gravity force pulls it back down to the Earth, which is a different type of force.

how density of arock can be determined using normal laboratory apparatus
Answer:
Explanation: Take the apparatus fill it with water which is enough to sink the rock, next write down the reading of the apparatus with only the water. next drop the rock in the water and write down the reading with the water and the rock. next calculate change in volume ( here volume is the reading in the apparatus). next find the weight of the rock.
Then put the values into this equation
Density = mass/volume
if you took all the units in SI units then the unit of density is Kg/m^3
The density of a rock can be determined using normal laboratory apparatus through a method known as the "Archimedes' principle" or the "water displacement method".
Materials needed: 1. Electronic balance or scale 2. Graduated cylinder or beaker 3. Water
1. Weigh the rock: Use an electronic balance or scale to measure the mass (weight) of the rock. Record this value in grams (g).
2. Find the rock's volume:
a. Fill the graduated cylinder or beaker with a known amount of water.
b. Note the initial water level reading in milliliters (ml).
c. Carefully lower the rock into the water, making sure not to splash or spill any water.
d. Measure the new water level in the graduated cylinder or beaker after the rock is submerged. Record the final water level reading in milliliters (ml).
e. The volume of the rock can be calculated by subtracting the initial water level from the final water level. This difference represents the volume of the rock displaced by water.
3. Calculate the density:
The density (ρ) of the rock can be determined using the formula:
ρ = Mass of the rock (in grams) / Volume of the rock (in milliliters)
4. Report the result:
The density of the rock is typically expressed in grams per cubic centimeter (g/cm³) or grams per milliliter (g/ml).
This method can provide a reasonably accurate determination of the rock's density. However, keep in mind that the density may vary slightly depending on the specific rock composition and porosity. For precise measurements or for rocks with complex structures, more sophisticated laboratory techniques may be employed.
