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?

Answer

1.negative work

2. kinetic energy and motion of ball

3. ball lost energy

4. kinetic energy

Explanation:

1:when you catch a ball that time their are two forces involved

a. force exerted by ball on your hand

b. Force exerted by you on ball  to stop it. Here the direction of force applied by you on the ball is in opposite direction to the motion of ball. it means direction of applied force and displacement of ball are in opposite direction it means work done by you on baseball is negative a.

2.When we catch a baseball that time we change its kinetic energy, force and its motion. A moving ball has kinetic energy and to stop the ball we have to change kinetic energy of ball. When we catch a baseball the kinetic energy of ball is transferred to our hand. When we catch a ball our hand moves in backward direction with ball because our hand gain energy.

3. Baseball lost energy and this energy is transferred to our hand.

4. Baseball has kinetic energy

he kicked it 10 feet straight up into the air? i think this works.
