Tambayoyi 3 game da lissafin Impulse
1. Mota mai nauyin kilogiram 250 tana tafiya da gudun kilomita 72/awa, sannan ta hanzarta da ƙarfi mai ɗorewa ta yadda cikin daƙiƙa 5 gudunta zai zama kilomita 80/awa. Ka ƙayyade motsin na tsawon daƙiƙa 5.
Wanda aka sani:
Nauyin motar (m) = 250 kg
Saurin farko (v o ) = 72 km/h = 20 m/s
Gudun ƙarshe (v t ) = 80 km/h = 22 m/s
Tazarar lokaci (t) = daƙiƙa 5
Ana so: Ƙayyade sha'awa (I)
Magani:
Tsarin Impulse: Impulse = Canjin Momentum
I = Δp
I = m (v t – v o ) = (250)(22 – 20) = (250)(2)
I = 500 kg m/s
2. Wani abu mai nauyin kilogiram 0.4 da farko yana tafiya da saurin mita 20/s, ƙarfin da ke tsayawa na N50 zai dakatar da shi a wani lokaci. Yaya girman motsin yake?
An sani :
Nauyi (m) = 0.4 kg
Gudun (vo o ) = 20 m/s
Saurin ƙarshe (v t ) = 0 m/s
Ƙarfi (F) = 50 N
Ana so: Impulse (I)
Magani:
Tsarin Impulse: Impulse = Canjin Momentum
I = Δp
I = m (v t – v o ) = (0,4)(0 – 20) = (0,4)(-20)
I = 8 kg m/s
3. Abu mai nauyin m yana motsawa a gudun da ba ya canzawa v, don haka motsin abu shine…
Magani
Turare = canjin motsi. Momentum yana canzawa lokacin da taro ko gudu suka canza. Don haka idan gudun da taro suka kasance iri ɗaya to babu canji a motsi. Don haka babu turare.
