|---|---|---|---|---|---|
| Fact | A true statement; A close agreement by competent observers of a series of observations of the same phenomena
🗑
|
||||
| hypothesis | An educated guess
🗑
|
||||
| law | Hypothesis that is tested over & over again and has not been contradicted; also known as a principle
🗑
|
||||
| principle | A general hypothesis or statement about a relationship of natural quantities that has been tested over and over again and has not been contracicted; also known as a law
🗑
|
||||
| scientific method | An orderly method for gaining,organizing, and applying new knowledge
🗑
|
||||
| theory | A synthesis of a large body of information that encompasses well-tested and verified hypotheses about aspects of the natural world
🗑
|
||||
| acceleration | The rate at which velocity is changing. The change may be magnitude, direction or both.
🗑
|
||||
| average speed | Path distance divided by time interval
🗑
|
||||
| elapsed time | the time that has passed since the beginning of an event
🗑
|
||||
| free fall | Motion under the influence of the gravitational force only
🗑
|
||||
| instantaneous speed | Speed at any instant of time
🗑
|
||||
| rate | how fast something happens or how much something changes per unit of time; a change in a quantity divided by the time it takes for the change to occur
🗑
|
||||
| relative | regarded in relation to something else. Depends on point of view or frame of reference. Sometimes referred to as "with respect to"
🗑
|
||||
| speed | How fast somtheing is moving; the path distance moved per time. The magnitude of the velocity vector
🗑
|
||||
| velocity | Speed together with the direction of motion.
🗑
|
||||
| equilibrium | A state of balance; The state of a body on which no net force acts.
🗑
|
||||
| force | Any influence that tends to accelerate an object; a push or pull; measured in newtons. A vector quantity.
🗑
|
||||
| friction | the force that acts to resist the relative motion (or attempted motion) of objects or materials that are in contact.
🗑
|
||||
| inertia | the reluctance of any body to change its stae of motion. Mass is the measure of inertia.
🗑
|
||||
| kilogram | The fundamental (base) SI unit of mass. 1 kg is the amount of mass in one liter of water at 4 degrees Celcius
🗑
|
||||
| law of interia | Every body continues in its stae of rest, or of motion in a straight line at constant speed, unless it is compelled to change that state by a net force exerted upon it. Also know as Newton's First Law
🗑
|
||||
| mass | A measure of an object's inertia; also a measure of the amount of matter in an object. Depends only on the amount of and kind of particles that compose an object-not on its location
🗑
|
||||
| net force | The combination of all the forces that act on an object
🗑
|
||||
| newton | SI unit of force. One Newton is the force applied to a one-kilogram mass that will produce an acceleration of one meter per second per second
🗑
|
||||
| Heliocentric solar system | sun centered solar system
🗑
|
||||
| Geocentric solar system | earth centered solar system
🗑
