Impulse-Momentum Theorem
The impulse experienced by an object is related to the change in its momentum when a force is applied. The impulse-momentum theorem states that the impulse, abbreviated as J, experienced by an object is equal to the change in its momentum, abbreviated as \({\Delta p}\). This relationship can be expressed as If a force ( \({F}\)) is applied to an object for a certain duration ( \({\Delta t}\)), the impulse experienced by the object is given by
Impulse-Momentum Theorem formulaThis equation shows that applying a force to an object for a certain duration results in a change in its velocity, and consequently, a change in momentum |
