m.
Section B: Give a short answer to the question given below.
State Newton’s second law.
According to Newton’s second law of motion, the
force
moment
acting on an object is
directly proportional
indirectly proportional
to the
rate of change of linear momentum of
rate of change of force acting on
the object, and the
change in momentum takes place in the direction of the force
change in force takes place in the direction of the moment
.
\(Force (F)\) \(=\) \(Mass (m)\) \(\times\) \(velocity (v)\)
\(Force (F)\) \(=\) \(\frac{Mass\ (m)} {velocity\ (v)}\)
\(Force (F)\) \(=\) \(\frac{Mass\ (m)} {Acceleration\ (a)}\)
\(Force (F)\) \(=\) \(Mass (m)\) \(\times\) \(Acceleration (a)\)
