Physics has always been my favorite subject, I am very good at it. I have a couple of certificates for this subject. I love learning how things work. For example, how does Newton's lamellar work? In Newton's cradle, the first ball transfers momentum to the second ball and stops. The second ball receives an impulse of potential energy from the first, but due to the impossibility of transforming the potential. Newton's lullaby, shows the conservation of inertia. Or a simple, familiar whirligig. A rapidly rotating whirligig does not fall due to the gyroscopic effect, but gradually due to friction, the angular velocity of its own rotation decreases. When the speed rotation becomes insufficiently large, the axis of the top begins to spiral-like deviate from the vertical (precess), and in the end the top stops rotating and falls. The spinning top is the simplest example of a gyroscope, which is an essential element in a number of navigation instruments.
Excuse me. I'm interviewing students about their typical day. Can I ask you some questions, please?
Lily : Yes, I'm not doing much. I 1 for my brother. He 2 trainers in that shop. Are you doing interviews for a magazine?

Katie; How do you17?
Lily; I go on the computer and chat, or18 if there's something good on.
