explain Newton's lawl of motion and obtain the formula for force from Newton's second law. class 9
Answers
Explanation:
First Law :- Every inanimate objects continues to be in its state of rest or of uniform unaccelerated motion unless and until it is acted Upon by an external, unbalanced force.
Second Law :- Rate of change of linear momentum of a rigid body is directly proportional to the applied force and takes place in the direction of the applied force.
F = dp / dt
(where F is the force and P = m v is the linear momentum)
hope this detailed answers may help you
Answer:
Newton's second law of motion is a=Fnetm a = F net m . ... The weight w of an object is defined as the force of gravity acting on an object of mass m. The object experiences an acceleration due to gravity g: w = mg. If the only force acting on an object is due to gravity, the object is in free fall.
FORMULA:
F= ma
