Momentum and Impulse
... If the force exerted on an object is NOT a constant force, finding the impulse/change in momentum is a little more difficult. As the saying goes, “If the forces varies… You must integrate!” ...

Newton 2nd Law
... Air track with accessory box, smart pulley, string, mass hanger with masses. Discussion The purpose of this experiment is to investigate Newton's 2nd Law of Motion. A small mass (m) will hang over a pulley at the end of the airtrack and will pull a cart of mass (M) along the length of the airtrack. ...

The Law of Conservation of Mechanical Energy
... Impulse causes a change in momentum. Thus, the change in momentum produced by an impulse is equal to the impulse in both magnitude and direction. Impulse = Change in Momentum From Newton’s second law, F.t = mvf = mvi Thus impulse has units of kg m/s OR Ns Questions on Momentum and Impulse Question 1 ...

Solutions
... for integers m, n, p, q such that the above formulae yield integers. [Hint: Use the previous exercise.] Proof. Rewrite the equation as x2 − t2 = z 2 − y 2 which is equivalent to (x + t)(x − t) = (y + z)(z − y) From the previous exercise there exist integers m, n, p, q such that x + t = mn x − t = pq ...

F = ma, Important Equation, Big Mistake
... Leibniz was specific about the value of the vis viva, i.e., mv2 . He referred to the expression “2mgh” as the force needed to lift a body a distance h, or the weight times the height. The author is not aware of how Leibniz handled the factor “2” on the left in eq. 4, or the factor “½” on the right i ...
