When a soccer ball is kicked the resulting motion of the ball is determined by Newton's laws of motion.From Newton's first law, we know that the moving ball will stay in motion in a straight line unless acted on by external forces.A force may be thought of as a push or pull in a specific direction; a force is a vector quantity.If the initial velocity and direction are known, and we can ...

The ball is protected by a guard, who tries to tag anybody approaching the ball before it's reached. If the guard succeeds in tagging everyone before anyone can kick the ball, he's the winner! If someone is able to out-maneuver the guard and kick the ball, however, she wins the game and becomes the new guard for the next round. Ball Tag.

Answer: Both balls are identical. Therefore, their capacitances C are equal. This means Q= CV is same for both. This shows that charges are so distributed that Q and V are equal for them after they are brought in contact and then separated. The total charge +3Q -Q= 2Q is shared equally. Thus, eac...

Charge comes in multiples of an indivisible unit of charge, represented by the letter e. In other words, charge comes in multiples of the charge on the electron or the proton. These things have the same size charge, but the sign is different. A proton has a charge of +e, while an electron has a charge of -e.
