Is the sum of kinetic and gravitational potential energy conserved in a closed system with no additional forces including gravit
patriot [66]
The acceleration due to gravity changes as we move away from Earth, and the expression for gravitational potential energy must reflect this change. The total energy of a system is the sum of kinetic and gravitational potential energy, and this total energy is conserved in orbital motion.

Two planets are 3 x 107 km apart. Planet A has a mass of 8 x 1024 kg. Planet B has a mass of 1 x 1025 kg.
eimsori [14]
Given:
m₁ = 8 x 10²⁴ kg, mass of planet A
m₂ = 10²⁵ kg, mass f planet B
d = 3 x 10⁷ m, the distance between planets A and B

The gravitational force between planets A and B is
F=G \frac{m_{1}m_{2}}{d^{2}}
where
G = 6.674 x 10⁻¹¹ (N-m²)/kg²
That is,
F =[ (6.674 x 10⁻¹¹ (N-m²)/kg²)*(8 x 10²⁴ kg)*(10²⁵ kg) ]/(3 x 10⁷ m)²
   = 5.9324 x 10²⁴ N

Answer:
Planet A exerts a force of 5.9324 x 10²⁴ N on planet B.
Planet B exerts an equal and opposite force om planet A.

Nearly all physics problems will use the unit m/s^2 for acceleration. Explain why the seconds are squared. Why isn't the unit gi
sertanlavr [38]

Because acceleration is not speed, and speed is not acceleration. 
I'm sure you would not ask "Why isn't temperature given in acres,
as it is for area ?"  Speed and acceleration are different things, so
it's only natural that they have different units.


The magnitude (size) part of acceleration is:

         (how much speed changes) per second.

Are you speeding up ?
Are you traveling (2 meters per second) faster every second ?
Then your acceleration is

           (2 meters per second) per second .

When you write that phrase as an algebraic expression, it's

           (2 m/sec) / sec

and when you simplify that fraction, you get        2 m/sec² .
