Question

DEFINE SECOND LAW OF MOTION ( CLASS 9 PHYSICS)


PLS DON'T GIVE IRRELEVANT ANSWERS

Answer 1

Answer:the rate of momentum is directly proportional to the applied unbalanced force in the direction of the force , f=ma

m= mass

a= acceleration

F= force

Answer 2

Newton's second law states that the force acting on the object is directly proportional to the rate of change of velocity.

• The rate of change of velocity is called acceleration, where the mass of the object is constant.
• Force the force acting on the object is the mathematical product of the mass of the object and acceleration produced in that object.
• Force ∝ (v-u)/t, where v is the final velocity, and u is the initial velocity, and t is the time about for which the velocity changes.
• (v-u)/t = acceleration
• Therefore, force = mass × acceleration
• Force is the vector quantity and its direction is determined by the direction of the force applied
