Question

define the Newton's second law of motion

Answer 1

The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
\[a = Fnet / m\]

Answer 2

F=dp/dt=d(mv)/dt=m dv/dt=ma
p is momentum. F is force. a is accelaration. v is velocity. t is time.

Answer 3

for a body moving in a constant motion, the applied force is directly proportional to acceleration as long as its mass remains constant
\[F \alpha Ma\]
