a lacrosse ball has 200 j of kinetic energy . how much kinetic energy does it have if it is thrown 3 times faster? how much more will it hurt if that ball hit you

When you change the position and speed of the ball in the carnival

game, you transfer energy to the ball. Energy is the ability of a person

or an object to do work or to cause a change. When you do work on an

object, some of your energy is transferred to the object. You can think

of work as the transfer of energy. In fact, both work and energy are

measured in the same unit, the joule.

The man in the photograph above converts one form of energy

into another form when he uses his muscles to toss the ball. You can

think of the man and the ball as a system, or a group of objects that

affect one another. Energy can be transferred from the man to the

ball, but the total amount of energy in the system does not change
