motion
is relative to the object that it is compared to
velocity
a vector whose magnitude is the speed of an object and whose direction is the direction of motion
constant acceleration
an object increases in speed 10m/s every second
m/s²
unit for acceleration in the SI system
average speed
distance/time
Galileo
concluded that in a vacuum all bodies near the surface of the Earth will fall at the same rate
instantaneous speed
the speed at any instant. this is also the slope of a tangent to the distance time graph at any point
speed
the slope of a distance vs. time graph
scalar
speed and distance are examples of thisvec
vector
velocity and displacement are examples of this
kilo
means one thousand
terminal velocity
the maximum velocity that a freely falling object reaches
distance traveled
the area under the curve of a speed vs. time graph represents this
