When you catch a baseball, what kind of work do you do, negative or positive? By catching the baseball, what do you change? Does the baseball gain or lose energy? What kind of energy?
i know 2
ok
1st would you think negative or positive
i think its neg.
k 2nd do yu hink gain or lose
lose
right
for the third i dont know
@cupcakesonice
thats ok:) u earned yourself another fan:)
thanks i will fan you to
@cupcakesonice might be able to help you
ok:) thank you
yep : D
can you do me a favor @Tattyspur
sure
can you see if you can help me with a question i posted a few minutes ago
its right above yours
So you are right- you would be doing negative work and you will lose energy. But what kind of energy would you be losing? Remember- we have potential and kinetic energy When you catch the ball, would you be converting the kinetic energy to potential energy or potential energy to kinetic energy?
you would lose the kinetic energy from the baseball and the kinetic energy would turn into potential from it stopping in your hand
Exactly! So you're losing kinetic energy wouldn't you say that's also something you're changing by catching the ball?
the amount of kinetic to potential energy?
yup
also remember work = Force * distance and the person throwing the baseball would be doing positive work you're doing negative work by catching the baseball because you're exerting a force in the opposite direction so that's another thing you're changing
right.
hopefully that helped :)
thnks soooo much :)
of course! Glad I could help :)
