Friction force
A force on objects or substances in contact with each other that resists motion of the objects or substances relative to each other.

Mass

Newton
– If no force acts on a body then a body
in motion will continue at a constant speed in a straight
line
North pole
the place where the northern rotational axis intersects the surface of a planet, moon, etc.
Reaction time
: the time required for a subject to initiate a prearranged response to a defined stimulus
Repel
o repel is defined as to hold off, refuse to accept or reject.
S.I units
The International System of Units is the standard modern form of the metric system.
