dynamics

Question 1

newton’s 1st law

Answer 1

an object will continue its state of rest or uniform motion in a straight line unless a resultant force acts on it

Question 2

newton’s 2nd law

Answer 2

when a resultant force acts on an object of constant mass, the object will accelerate and move in the direction of the resultant force. the product of the mass and acceleration of the object is equal to the resultant force (F=ma)

Question 3

newton’s 3rd law

Answer 3

for every action (force), there is an equal and opposite reaction, and these forces act on mutually opposite bodies
