physics free fall
when the acceleration due to gravity =10 m/s2 at the end of the first sec of free fall the reaches a speed of...
10 m/s
gravity is a vector quantity that has a magnitude of ------- and a ------ direction
10 m/s2 downward
the equation v=gt simplifies to
10t
the equation d=1/2 gt2 simplifies to
5t2
a straight line on a speed vs time graph represents constant------
acceleration
constant acceleration
an object that falls freely in a vacuum, its velocity (speed) increases at a constant rate known as constant acceleration.
a straight line on a distance vs time graph represents ----- speed
constant
gravity always acts
downward
elapsed time
elapsed time is the amt of time that has passed sinced the beginning of motion
an object moving under the influence of only gravity is said to be in
free fall
when and object is in free fall it falls a ----- distance each time unit
greater
on graphs of motion, time is always plotted in the ---- axis, on distance-time graphs, distance is plotted on the ---- axis
horizontal, vertical
the speed of a freely falling object is constantly -----
moving
gravity is considered a
negative downward force
instantaneous speed from rest=
o m/s
free fall
object in free fall will experience constant acceleration gravity is the only force acting on the object the is no air resistance force acting on the object.
equation v=gt is the ----- of a freely falling object
speed or velocity
when falling with constant acceleration------ and ------ are directly proportional
time and speed
