Quantity
Explanation
1-) Velocity
2-) Acceleration
3-) Force
4-) Mass
5-) Volume
a-) …. is any interaction that, when
unopposed, will change the motion of an
object.
b-) …..is a physical vector quantity; both
magnitude and direction are needed to
define it.
c-)… is the quantity of three-dimensional
space enclosed by some closed boundary,
for example, the space that a substance
(solid, liquid, gas, or plasma)
d-) is the rate of change of velocity of an
object.
e-) …..is a property of a physical body which
determines the strength of its mutual
gravitational attraction to other bodies, its
resistance to being accelerated by a force,
and in the theory of relativity gives
the mass–energy content of a system
