Kumhanya inhamba yevector, nepo velocity iri nhamba yescalar. Kumhanya kune hukuru negwara, nepo velocity ine hukuru chete. Chiyero chepasi rose mamita pasekondi, chakapfupikiswa m/s kana ms -1 . Chiratidzo chayo ndi v ( velocity ).
Avhareji yekumhanya uye avhareji yekumhanya
Muenzaniso wezvinetso.
1. Mudzidzi anofamba kumabvazuva mamita maviri musekondi imwe chete. Avhareji yekumhanya uye hukuru hwekumhanya kwemudzidzi chii?
Kukurukurirana
Avhareji yekumhanya = 2 m/s
Avhareji yekumhanya = 2 m/s
Ara = gwara kudzingwa = kumabvazuva
2. Mudzidzi anofamba kumabvazuva kwemamita maviri musekondi imwe, ozofamba kumadokero mita imwe mumasekondi maviri. Avhareji yekumhanya kwemudzidzi uye avhareji yekumhanya chii?
Kukurukurirana
Avhareji yekumhanya = (2 metres + 1 metres) / (1 sekondi + 2 seconds) = 3 metres / 3 seconds = 1 m/s
Huru = (2 metres - 1 metres) / (1 sekondi + 2 seconds) = 1 mita / 3 seconds = 1/3 m/s
Ara = gwara rekufamba = kumabvazuva.
Kumhanya nekukasika uye kumhanya nekukasika
Kumhanya ipapo ipapo = daro diki kwazvo / nguva pfupi kwazvo. Nemamwe mashoko, kumhanya nekukurumidza idaro diki kwazvo rinofambwa munguva pfupi kwazvo. Kana wakambotasva mudhudhudhu kana mota, uchaona kuti kumhanya kwemudhudhudhu kana mota kunogara kuchichinja nguva dzese mudhudhudhu kana mota ichifamba. Kumhanya uku nekukurumidza kunoratidzwa ne speedometer.
Kukura kwekumhanya kwepakarepo = kutama kudiki kwazvo / nguva pfupi kwazvo. Nemamwe mashoko, kutama kudiki kwazvo kwakafamba kwenguva pfupi kwazvo.
Zvakakosha kuziva kuti tinogona kutsiva velocity ne speed . Velocity inoonekwa seyakafanana ne velocity nekuti daro ne displacement zvakaenzana kana zviri zvidiki kwazvo. Kunyangwe daro ne displacement zvisiri nguva dzose zvakaenzana (tarisa hurukuro pamusoro pe daro ne displacement), kana daro ne displacement zviri zvidiki kwazvo, zvinofanira kuva ne value imwechete.
