The weight of an object is the product of its mass, mmm, and the acceleration of gravity, ggg (where g=9.8 m/s2g=9.8 m/s2). If an object’s mass is m=10. kgm=10. kg, what is its weight?
Express the weight with the appropriate units.
F=ma
F = force (N)
m = mass (kg)
a= acceleration (m/s2)
When dealing with the acceleration due to
gravity:
W=mg
W = weight (N)
g = acceleration due to gravity
(9.8 m/s2 for surface of Earth)
Warmup:
and
Force is measured in
acceleration is measured in
and mass is measured in
If we know the force exerted on an object (in Newtons) and we know the mass of the object (in
kilograms) we can easily find the acceleration the object experiences by dividing the
the
by
If we know the force exerted on an object (in Newtons) and we know how fast the object accelerates
(in m/s?) then we can easily find the mass of the object experiences by dividing the
the
by
if we know the mass of an object in kilograms, and we know the acceleration that an object
experiences then we can calculate the force exerted on that object by multiplying the
unit!
