David explains the idea behind the sling to his fellow soldier friends using Physics.
Now, I will teach you soldiers how to use the sling using Physics!
We know that the sling undergoes a uniform circular motion, which means that the rock in the pouch is moving in a circular motion at a constant speed
David now explains the concept of centripetal force
The centripetal force is a force that acts on a body moving in a circular path and is directed towards the center around which the body is moving.
Moreover, the centripetal acceleration is the rate of change of tangential velocity.
When a body is moving in a circular path at a distance "r" from its center, its velocity at any distance will be directed tangentially.
This leads us to the final term in today's lesson, which is the tangential velocity.
This is how the sling works guys. As you spin the rock in the pouch, it moves in a uniform circular motion, where the direction is constantly changing. As we let go of one side of the sling, the rocks gets projected tangentially from the sling.
