Answer:
A force unit is defined as the product of a mass unit and a unit of acceleration.
Answer:
Force can be defined as a push or a pull that changes or tends to change the state of rest or uniform motion of an object or changes the direction or shape of an object.
Explanation:
Force = M (Mass) * A (Acceleration)
The SI unit of Mass = KG
S.I. unit of acceleration is m/sec/sec = m/sec2
Hence, Unit of force is Kg m/Sec2
Since force is used so often, S. I. gives this unit a special name:
1 Newton = 1 kg m/sec2

Answers
Answer:
B Both are directly related to movement.
Endocrine system and muscular system are directly related to movement while both stretching and constricting exercises are important for muscle health. So, the correct options for 1 and 2 are B and A respectively.
What is Endocrine system?The endocrine system is defined as the communication system made up of feedback loops that send hormones released by an organism's internal glands into the circulatory system, controlling distant target organs. The neurological control center for all endocrine systems in vertebrates is the hypothalamus. The endocrine glands lack ducts that would transport their output to the surface. These are known as glands without ducts.
Growth and development, metabolism, and reproduction are just a few of the essential processes in the body that are regulated by the hormones the endocrine system secretes. Movement has a close relationship with the endocrine and muscle systems.
Therefore, the correct options for 1 and 2 are B and A respectively.

a body has a weight of 2.8 Newtons what is the Mass of the body in grams
Answers
Answer:
285.7 g
Explanation:
Weight = mass x gravity
mass has units of kilograms
gravity is 9.8 m/s²
newton units are kg m / s²
So:
2.8 kg m/s² = mass x 9.8 m/s²
Divide both sides by 9.8
2.8 kg m/s²
---------------- = mass in kg = 0.2857kg
9.8 m/s²
Convert kilograms to grams by multiplying by 1000
0.2857kg 1000 g
-------------- X --------------- = 285.7g

Answers
Answer:
[tex]4m/s^{2}[/tex]
Explanation:
I'm assuming the units for force and mass are Newtons and kilograms, respectively.
Rearranging Newton's first law (F=m*a) to solve for acceleration:
F=m*a
[tex]a=\frac{F}{m}=\frac{400 N}{100 kg}=4m/s^{2}[/tex]
The acceleration is 4 meters per second squared and was found by rearranging Newton's first law in order to solve for acceleration.

2. For athletes, a focus on body mechanics improves the effectiveness of their efforts.
A.
True
B.
False
Answers
The answers are 1. According to Newton's second law, object A, being heavier, requires more force to be set in motion and will travel faster than object B. The correct answer is options C. and 2. Focusing on body mechanics is important for athletes as it improves their effectiveness, and technique, and reduces the risk of injury is a true statement.
1. According to Newton’s second law of physics, if there are two objects of equal size but object A is heavier than object B, then the statement that is true is option C: Object A will require more force to be set in motion but will travel faster than object B. Newton's second law of motion states that acceleration is directly proportional to the force applied and inversely proportional to the object's mass. Since both objects are of equal size but object A is heavier, it will require more force to be set in motion. However, once in motion, it will have more inertia and travel faster than object B.2. The statement "For athletes, a focus on body mechanics improves the effectiveness of their efforts" is True. Body mechanics refers to the way in which the body moves and maintains balance while performing a physical task. Athletes need to have proper body mechanics to achieve maximum efficiency and reduce the risk of injury. By focusing on their body mechanics, athletes can improve their technique, reduce unnecessary movements, and improve their overall performance. Good body mechanics can also help to prevent injury and reduce wear and tear on the body. Therefore, a focus on body mechanics is essential for athletes to maximize their performance while minimizing their risk of injury. In summary, Newton's second law states that a heavier object requires more force to be set in motion, while a focus on body mechanics can improve the effectiveness of athletes' efforts.For more questions on Newton's second law
