Question
What is Newton's first law? give example.
Answer
-
And object are at rest remains at rest and object in motion remains in motion unless acted on by all unbalanced force
-
F=m(a) all forces are unbalanced and the object has accleration which depends on net force and mass of an object
-
For every action there is an opposite and equal reaction
Question 23
Question
What is newtons 2nd law?
Answer
-
An object at rest remains at rest and object in motion remains in motion unless acted on by an unbalanced force
-
All forces are in balance and the object has acceleration which depends on the net force and mass of the object F = M(a)
-
For every action there is an opposite and equal reaction
Question 24
Question
What is newtons third law
Answer
-
An object at rest remains at rest and object in motion remains in motion unless acted on by an unbalanced force
-
all forces are unbalanced and the object has acceleration which depend on net force mass of an object f=m(a)
-
Every action there is an opposite and equal reaction
