(true or false) The moving objects only have energy, while the objects that don't move have no energy
false
(write the scientific term) The form of energy that increases when the speed of an object increases
kinetic enrgy
(give reason) The goal net vibrates when a ball hits it
because the kinetic energy transfers from the moving ball to the goal net
(What happens to ) the energy of a stopped ball at the top of a ramp starts to move down
the stored potential energy changes into kinetic energy
(write the scientific term) the ability to do work or cause change
energy
(true or false) Any moving object has a form of energy known as kinetic energy
true
(what happens if ) you transfers a book from the ground to a higher shelf (according to its potential energy)
the potential energy increases
