hola, me acabo de mudar a españa y voy a empezar 4to de la eso, el caso es que en mi pais no dan fisica hasta el equivalente a 4to de la eso, por lo que no tengo muchas bases, que debería estudiar/repasar para que no me vaya tan mal?

science is a systematic and logical approach to discovering how things in the universe work. true to this definition, science aims for measurable results through testing and analysis. science is based on fact, not opinion or preferences. the process of science is designed to challenge ideas through research.

explanation:

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
