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

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!

- You may attempt this question 3 more times for credit. In this problem, we will directly calculate the surface gravity and your weight on another planet. In metric, your weight is measured in "Newtons", and 1 Newton = 1 kg m / s². Newton's constant G = 6.67 x 10-11 m³/(kg s²). Earth has a mass = 5.97 x 1024 kg and a radius of 6378 km. You should be able to verify that g = 9.8 m/s² on Earth using the formula for surface gravity. If your mass is 64 kg, you should also be able to verify you should weigh 626 Newtons. If you can do that you should be OK for what's next. The mass of Venus is 4.87E+24 kg, and it's radius is 6.05E+3 km. What is the surface gravity of this planet?
