Why does an object traveling in a circle at a constant speed always accelerate ?

Answers

Answer 1

Answer: Because "acceleration" doesn't mean "speeding up". It means any change
in the speed or direction of motion.

An airplane speeding up, a bicycle slowing down, and a car going around a curve, are all doing accelerated motion.

A circle has no straight parts, so an object traveling in a circle is always changing
its direction. That means accelerated motion, even if its speed doesn't change..

Answer 2

Answer: I'm not sure but I believe it is momentum, when an object keeps moving and keeps Its speed

Evaporation: Large amounts of water evaporates from the Earth's ________, _______, __________ every day. The water vapor (evaporation) becomes part of the ________.

Answers

my guesses would be

surface,oceans,rivers,atmosphere

Possible answers:

oceans/seas/lakes/rivers

atmosphere/sky

Explanation:

Most of the air's moisture evaporates from rivers, lakes, seas, and oceans. Water at the surface of the Earth evaporates into water vapor, which rises into the sky and forms clouds, which eventually release water back onto Earth as precipitation.

why is the chemical energy of a battery potential energy and not kinetic energy?

Answers

The energy is 'stored' in the battery. The energy in the battery is able to start a motion and by doing so transfering to kinetic energy, nut the chemical energy in the battery isn't 'stored' in movement.

Kinetic energy is simply the energy of something in motion,
and the battery is just sitting there, even if it's fully charged.

A fully charged battery has the potential to cause heating,
light, an electric current, or the motion of something like
a motor or the clapper of a bell. What kind of energy it
produces depends on how you use it. You might use it
to produce kinetic energy, and you might not. Until you
connect it to something, its energy stays inside, in the
form of chemical energy, and nothing is moving yet.

How does lightning occur?

Answers

I've learned that lighting occurs when clouds in the sky bump into each other. The harder the clouds bump into each other, the louder and bigger the lighting gets :D

The positive and negative electrons split in the cloud

Positive going to the bottom of the cloud and negative to the top.

Since you are made of negative electrons, you attract the positive electrons to you causing you to get struck by lightning.

The ground has negative electrons too!

This will shock the ground and end up shocking you as well, since the ground and you are connected.

Lightning and thunder are connected! They do happen at the same time. The reason why the thunder travels later than the lightning is because you are away from the lightning and the sound waves are just getting near you

B.) How are thunderstorms dangerous?

Thunderstorms are dangerous because they give off positive energy. If you are standing outside while a thunderstorm is in session, you could get shocked since you are made of negative energy and attract positive energy.

If your hair is sticking straight up, you are about to be struck by lightning. Crouch down and cover your head next to your ears and prepare for impact.

You might ask, "Why can't I just run from the lightning?" That is true, but since you aren't faster than light itself, you will still wind up caught in the storm.

Avoid this by staying inside.
