When a pendulum swings if it is not continuously pushed it will stop eventually because some of its energy is changed into blank energy?
The energy changes into is Thermal energy because of the friction caused by it moving produces heat. [Hope it helps]
How are objects able to gain energy as well as use it?
An object gains energy when it is either heated or pushed. If pushed vertically, it gains gravitational potential energy. If pushed horizontally, it gains kinetic energy.
A 10 kg rock is pushed off the edge of a bridge 50 meters above the ground. What was the kinetic energy of the rock at the midway point of its fall?
2450
A 10 kg rock is pushed off the edge of a bridge 50 meters above the ground. what was the kinetic energy of rock befor it began to fall?
zero
A rock weighing 98 newtons is pushed off the edge of a bride 50 meters above the ground what was the kinetic energy of the rock before it began to fall?
zero

If a stone is pushed from the top of the hill what kind of energy would it have halfway down the hill?
It would have an almost equal balance between gravitational potential energy and kinetic energy. The discrepancy comes from energy lost as heat via friction with the air and ground.
Give an example of gravitational potential energy?
a book sitting up on a shelf. gravity can potentionally pull it down if pushed.
