Answer: holding the ball in the air without moving it
Explanation:
When the ball goes up it’s potential energy
Explanation:
Two objects that only have the force of gravity acting on them, will fall with the same acceleration <span>g=9.8<span>m<span>s2</span></span>; g=32.2<span><span>ft</span><span>s2</span></span></span> and will therefore hit the ground at the same time.
When you drop a feather, air resistance acts on all the surfaces of the feather. This causes the feather to slow down.
Air resistance depends on two factors: the speed of the object (increased for example by throwing it), and its surface area.
hope this can give u a little bet more to know about how to get ur answer :P
have a gud day and gud luck!
They don't have free electrons moving around (delocalised electrons) so they can't conduct electricity which gives them the property of good insulators.
Answer:
It is Conductivity because it is the measure of the ease.
-- Kinetic energy is the energy of mass in motion. The amount is determined by the mass of whatever is moving, and its speed.
-- Potential energy is the energy that's stored up in some form, not being used yet but ready to be used when you want it.
For example, one form of it is <u><em>chemical</em></u><em> </em>potential energy, like in a battery, or a match. You get the energy out of a battery when you connect it to a motor or a light. You get the energy out of as match when you make the tip hot and it flares up.
This question is asking about <u><em>gravitational</em></u> potential energy. An object has stored energy just by being up high, like a bowling ball on a shelf. You get the energy out of it just by dropping it ... possibly enough to crack the floor !
The amount of this kind of potential energy is determined by the mass of the object, and how high up it is.
-- Getting the answers from other people doesn't help you a bit, until you understand them and can answer the question on your own.
