velocity
speed
speed
velocity
- Speed (\(v\)) measured in m/s
- Velocity (\(\vec v\)) measured in m/s
newton's third law
force pair
force twins
If A exerts a force on B,
then B also exerts a force on A.
These forces have the same strength,
are the same type,
and point in opposite directions.
net force
acceleration
newton's second law
mass
inertia
The acceleration of an object is equal to the net force on it, divided by its mass.
\(\vec a=\frac{\vec F_{net}}{m}\)
