Question | Answer |
Energy exists in what two states? | kinetic and potential |
What is the energy of motion? | kinetic energy |
Moving objects have what type of energy? | kinetic energy |
Which energy is stored (or waiting to be used) energy? | potential energy |
A rock on top of a hill has what type of energy - potential or kinetic? | potential energy |
A book on a shelf has what type of energy - potential or kinetic? | potential energy |
How fast an object moves in a certain amount of time is called what? | speed |
Any push or pull that causes an object to move, stop, or change speed or direction is called? | force |
To mov e a large (massive) object you will need greater or lesser force? | greater |
forces are measured in units called? | Newtons |
Newtons are named after what British scientist who explained how force and motion are related? | Sir Isaac Newton |
What works against (opposes) motion and causes objects to slow down and stop? | friction |
Unless acted upon by a force, objects in motion tend to stay in motion or remain at rest? | stay in motion |
Unless acted upon by a force, objects at rest tend to stay at rest or in motion? | stay at rest |
What property of matter states that an object at rest will stay at rest, and an object in motion will remain im motion unless acted upon by an outside force? | Inertia |
What force is pulling you toward the Earth's surface? | gravity |
What is the force that is used to move an object a certain distance called? | work |
What is the ability to do work (either to mak an object move or to change matter) called? | energy |
What instrument measures air pressure? | barometer |
What instrument measures wind speed? | anemometer |
What instrument measures precipitation (water)? | rain gauge |
What instrument measures the temperature of the air? | Thermometer |
What instrument tells the direction of the wind? | weather vane |
What is the Water Cycle? | The never-ending movement of water through evaporation, condensation, and precipitation. |
What is condensation? | Whater particles lose heat energy, slow down, and change from a gas to a liquid (condense). |
What is the measure of the amount of heat energy in the atomosphere? | temperature |
What is due to the weight of the air and is determined by several factors including the timperature of the air? | air pressure |
Large regions of air with the same weather are called? | air masses |
What is the boundary between air masses of different temperature and humidity? | a front |
What is it called when a warm air mass pushes into a cold air mass usually causing light rain? | warm front |
What is it called when a cold air mass pushes into a warm air mass often causing violent weather? | cold front |
What isis it called when air masses (warm or cold) don't move? | stationalry front |
What are associated with certain weather conditions and are maide up of tiny droplets of necdensed water in the atmosphere? | clouds |
What are te feathery cluds associated with fair weather and often indicate that rain or snow will fall within serveral hours? | cirrus clouds |
What are smooth, layered, gray cluds that cover the whole sky (blockout direct sunlight) and usually associated with light rain and drizzle? | stratus clouds |
What are the white, fluffy cluds with flat bottoms that usually indicate fair weather, howver, when they get larger and darker on the bottom, they produce thunderstorms? | cumulus clouds |
What are larger and darker cumulus clouds that produce thunderstorms called? | cumulus-nimbus |
Extreme atmospheric conditins can create these kinds of storms? | thunderstorms, hurricanes, and tornadoes |
What is a measurement of how much water vapor is in the air? | humidity |
What type of scientist uses data to predict weather patterns? | meteorologist |
