Read the following: mass is a physical quantity and general property of matter, which expresses the inertia or resistance to change of motion of a body. More precisely, it is the property of a body that determines its acceleration, when it is under the influence of a certain force. According to the previous paragraph where you explain what the mass is, you could choose the difference between the mass and the weight:
-The mass is the physical magnitude that indicates the amount of matter that a body contains. Weight is a scalar quantity that expresses the three dimensions of a body: length, width, and height.
-The mass is the amount of matter in the bodies. Weight is the force that gravity exerts on a mass.
-the weight of a body depends on its amount of matter, it does not depend on gravity. The more mass a body has, the greater the weight. The mass always remains the same no matter where it is.
2. Choose the correct answer for a situation where the property of weight is explained:
the weight involved is the weight applied to the body, in turn is the normal weight.
-When a car travels forward and then brakes, passengers will feel a slight pull forward. If a tablecloth is pulled quickly, things on top of it will not fall due to the weight of bodies remaining at rest.
-When we make purchases in a supermarket of various food products, here it is evident that the unit of measurement is grams and the instrument of measurement is the scale.
How would you define volume in a sentence:
Measures of the three-dimensional space occupied by a body
As volume we designate the physical magnitude with which we measure the amount of matter that a body contains
volume is the resistance that one body opposes to another taking its place in space: no body can occupy the place of another at the same time
what do you think divisibility is:
Divisibility: identify the general properties of matter. There are common or general properties that are manifested in all types of matter, without exception.
Divisibility: Weight is the amount of elements that come from the earth, that is, it is determined by gravity or even disappears if it is canceled.
Divisibility: it is the property that matter has of being divided into very small particles
this year my dad went to work in Melgar and I went to live with him for more than a month and on one of those days I went to explore the club where he was living and found a carpentry shop and accidentally hit rib with something too tough and so far it still hurts. according to the above, what property of the matter is being evidenced.
mass: because when I hit myself with the object, I hit myself with all the mass that that object had
weight: because when I hit myself with the object, I hit myself with all the weight that the object had
hardness: because when I hit myself with the object, since that object is very hard, that is why my rib still hurts
Impenetrability is the resistance that a body opposes to another taking its place in space: no body can occupy the place of another at the same time. Likewise, impenetrability is the resistance that a body opposes to being pierced. According to the above, in the movies when they went through the walls what material do you think they were:
the cardboard: because the cardboard is impenetrable and being impenetrable it is easy to go through.
cardboard: because cardboard is penetrable and being penetrable it is easy to pass through.
carton straw: because the cardboard straw is impenetrable and being impenetrable it is difficult to cross.
Read the following and answer the question: Inability of bodies to modify by themselves the state of rest or movement in which they are. According to the above, which of these is a clear example of inertia:
a concrete wall, you can't get through it by hand.
How much do the pasta weigh
Which of these options shows that the rest are immersed?
Tomorrow I'm going to have a sleepover at Camila's house and I'm super excited because we're going to stay up
Girls I'm sleepy, are we going to sleep? If I'm sleepy too, we should sleep * fall asleep *
Goodbye teacher happy weekend, well now I have time to rest like the poor computer * you turn off the computer *
Read the following paragraph: Physical changes are those that modify the appearance or presentation of matter, but never its composition. Some more common examples of physical changes in matter are: crumpling a piece of paper or stretching a ball of clay to the maximum. According to the above mentioned which of these is a physical change:
make popsicles
make a fire
do the digestion
In chemical changes, new substances are produced totally different from the initial substances. Let's see for example: in the case of the complete combustion of a combustible material such as firewood, the final products are: carbon dioxide (gas), water vapor, energy in the form of light and heat and ash. In the previous paragraph, what is a clear example of a chemical change?
apply perfume
photosynthesis
break a mirror
