Tension force |
| Answer» Tension is physical or mental strain, the force created by pulling something tight or a strain in a relationship. An example of tension is the feeling of working to meet an established deadline. An example of tension is pulling the two ends of a rubber band further and further apart from each other. | |

Integration of 3rd equation of motion |
| Answer» 3rd motion : 2as=v^2-u^2S=1/2(v+u)tS=(v+u÷2)tS=v\'tNow expand v\'tV\'t=[v+u÷2][v-u÷a]. [t=v-u÷2]nowV\'t=v+u/2×v-u/aThen V^2-u^2=2asThus we derived the third equation of motion | |
