Mathematical formulation of second law of motion. Explain.

Answer» It states that rate of change in momentum is equals to the applied force ..................as we know that force is equals to F=M×a.........(1)(here accelaratiin is defined as a=v-u/t) so putting the value of a in the equ. 1 we have .........F=M(v-u)/t or (Mv-Mu)/t here Mv and Mu are the final and initial momentum of the body so now we have F=(Pf-Pi)/t ....wow this is the newtons second law in mathematical form derived by the definition of force
Let mass of an moving object = mLet the velocity of the object changes from \'u\' ; to \'v\' in the interval of time \'t\'This means, Initial velocity of the object = u.Final velocity of the object = vWe know that momentum (p) = Mass x velocityTherefore,Momentum (p) of the object at its initial velocity u = m × u = muMomentum (p) of the object at its final velocity v = m × v = mvThe change in momentum = mv − muRate of change of momentum = (mv−mu)/ t
4807.

What is the first equation of motion

Answer» The final velocity (v) of a moving object with uniform acceleration (a) after time, t.Let, the initial velocity = u.Final velocity = v.Time = tAcceleration = aWe know that, Acceleration (a) =Change in velocity/Time taken⇒a = (Final velocity-Initial velocity)/Time taken⇒ a = (v − u)/t⇒ at = v − u⇒ at − v = −u⇒ −v = −u − at⇒ v = u + at ---(i)This equation is known as first equation of motion.\xa0

Define Three Laws Of Motion

Answer» The first law of motion is whenever a body is in motion it will be in motion or whenever the more what is in rest it will be in rest until or unless the force is not applied the second law of motion is that the force is directly proportional to the change in momentum per unit time and the last and third law of motion is that every action is equal and opposite of the reaction
Thirth law of motion states that every action has equal and opposite reaction

What is balanced and unbalanced force

Answer» Balanced Forces: If the resultant of applied forces is equal to zero, it is called balanced forces. Example: In the tug of war if both the teams apply similar magnitude of forces in opposite directions, rope does not move in either side. This happens because of balanced forces in which resultant of applied forces become zeroUnbalanced Forces: If the resultant of applied forces are greater than zero the forces are called unbalanced forces. An object in rest can be moved because of applying balanced forces.
