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
