Studied by 0 peoplefree fall
the ideal falling motion of something subject only to a gravitational field. no air resistance
height
the vertical dimension of extension; distance from the base of something to the top
mass
amount of matter, how many particles (kg, g)
projectile
a weapon that is forcibly thrown or projected at a targets but is not self-propelled
vertical
something that is oriented vertically, up and down
horizontal
something that is oriented horizontally, left to right, side to side
resultant
overall, combination, result of two or more vectors
components
individual pieces of vector, usually x-direction, y- direction
acceleration
a rate of increase of velocity, due to gravity. vertical.if it's horizontal, no acceleration not moving
displacement
change in position, start to end. total length traveled. units: m, km
distance
how far something is. units: m, km
speed
how fast something goes. units: m/s, km/h
velocity
how fast in a direction. units: m/s, km/h, NSEW, foward or backward
scalar
just a number magintude with a unit, speed and time
vector
has direction, velocity and displacement
average speed
total time and total distance
average time
divide the total time by the product of the subtraction
average velocity
the change of displacement divided by the time intervals in which the displacement occurs
