|
Acceleration due to gravity (g) |
Acceleration on a freely falling object. It's value near Earth's surface is about 9.8 m/s each second.
|
|
|
Rate |
How fast something happens or how much something changes per unit of time; a change in quantity divided by the time it takes for the change to occur.
|
|
|
mi
|
abbreviation for mile
|
|
|
Instantaneous Speed
|
Speed at any instant.
|
|
|
m
|
abbreviation for meter
|
|
|
CG
|
Abbreviation for center of gravity
|
|
|
Acceleration a)
|
Rate at which an object's velocity changes with time; the change in velocity may be in magnitude (speed), or direction, or both.
|
|
|
Vector Quantity
|
Quantity in physics that has both magnitude and direction. Examples are force, velocity, acceleration, torque, and electric and magnetic fields.
|
|
|
Velocity
|
Speed of an object and its direction of motion, a vector quantity.
|
|
|
Scalar Quantity
|
Quantity in physics, such as mass, volume and time, that can be completely specified by its magnitude and has no direction.
|
|
|
Linear Motion
|
Straight-line motion, as opposed to circular, angular, or totational motion.
|
|
|
Telescope
|
Optical Instrument that forms images of very distant objects.
|
|
|
Free Fall |
Motion under the influence of gravity only.
|
|
|
Average Speed
|
Path Distance divided by Time Interval.
|
|
|
Speed
|
How fast something moves; the distance an object travels per unit of time, the magnitude of velocity
Average speed, linear speed, rotaional speed, tangential speed |
