Question

State Newton's second law of motion. By using this deduce an expression for force. Obtain the unit of force from the above law and define it

Answer 1

newtons second law tells us that :
acceleration  is directly propotional to force 
but accelleration is inversly propotional to mass 

therefore cpmbining the two 
a is propotional to f/m

therefore a = k*m/a 
where k is force constant 
if k is 1 
then a= f/m 
rearanging it f=ma 

the untit of force is newotons 

sorry dont know the derinition of newton

Answer 2

Answer:

using the above law deduce an expression for force
