Papatipu me te taumaha – ngā raruraru me ngā otinga

Ngā whakaoti rapanga i roto i ngā ture nekehanga a Newton – te papatipu me te taumaha

1. Ko te taumaha o te papatipu 1 kg i te mata o te Ao ko… karamu = 9.8 m/s ²

Mōhiotia:

Taumaha (m) = 1 kg

Ko te whakaterenga nā te kaha ā-papa i te mata o te Ao (g) = 9.8 m/s ²

E hiahiatia ana: taumaha (w)

Rongoā:

w = mg

m = papatipu (Ko te waeine SI mō te papatipu ko te kirokaramu, kg)

g = te whakaterenga nā te kaha ā-papa (Ko te waeine SI o g ko m/s ² )

w = taumaha (Ko te waeine SI o w ko kg m/s ² , ko Newton rānei)

Taumaha:

w = (1 kg)(9.8 m/s² ⁾ = 9.8 kg m/s² ⁼ 9.8 Newton

(a) Tuhia te kaha o te papa taumaha (taumaha) e pā ana ki te mea ina okioki te mea i runga i te tēpu, e whakaaturia ana i te pikitia (a).

(b) Tuhia te kaha o te taumaha (taumaha) me ōna wāhanga e pā ana ki tētahi mea e reti ana i raro i tētahi papa whakarara , e whakaaturia ana i te ahua (b)

3. Ko te taumaha o tētahi pouaka he 1 kg, ā, ko te whakaterenga nā te kaha ā-papa he 9.8 m/s² ^. Kimihia (a) te taumaha (b) te wāhanga whakapae me te wāhanga poutū o te taumaha.

Taumaha: w = mg = (1 kg)(9.8 m/s² ⁾ = 9.8 kg m/s² ⁼ 9.8 Newton

Ko te wāhanga whakapae o te taumaha:

w _x= w sin 30 ^o = (9,8 N)(0,5) = 4.9 Ngā Newton

Ko te wāhanga poutū o te taumaha:

w _y= w cos 30 ^o = (9.8 N)(0.5√3) = 4.9√3 Ngā Newton
