velocity - ANS how fast a body is being displaced and the direction in which it
is headed
m/s
velocity formula and unit - ANS displacement/time
m/s
speed formula and unit - ANS distance/time
m/s
average velocity formula - ANS (final velocity + initial velocity)/2
acceleration - ANS the rate at which velocity changes
acceleration formula and units - ANS (final velocity-initial velocity)/time
m/s^2
acceleration of gravity (g) units - ANS 32 ft/s^2 or 9.8 m/s^2
force - ANS any influence that can change the velocity or acceleration of a
body
force formula and unit - ANS F = ma
F = mass * acceleration
