1)Newton's laws of motion are concerned with relationships among
a) force, mass and motion
b) Displacement, mass and acceleration
c) Velocity, fore and acceleration
d) mass, acceleration and velocity
I feel that thay deal with force, mass and motion which is A, am I correct
2)The motion of an objct thrown vertically upward is affected by the acceleration of gravity
A) During its upward motion
B) During its downward motion
C) During both upward and downward motion
D) A variable manner
I feel it is C because gravity is always there, am I correct?
1. first law is mass and velocity
second law is force and acceleration
third law is force and force.
so
mass, motion, force
agree
Yes, both up and down net force = m g down
1) Yes, you are correct. Newton's laws of motion are concerned with the relationships among force, mass, and motion. These laws describe how the motion of an object changes when acted upon by external forces. In particular, the first law (also known as the law of inertia) states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. The second law describes how the velocity of an object changes when subjected to an external force, and it relates force, mass, and acceleration. The third law states that for every action, there is an equal and opposite reaction, which relates to the forces exerted by interacting objects.
2) Your reasoning is correct. The motion of an object thrown vertically upward is affected by the acceleration of gravity both during its upward and downward motion. When the object is thrown upwards, the force of gravity acts against its motion, gradually slowing it down until it comes to a stop at its maximum height. Then, during its downward motion, the force of gravity acts in the opposite direction, accelerating the object towards the ground. Therefore, the acceleration due to gravity affects the object's motion during both upward and downward phases.
