Highest point  ( A ) ...

Not moving       ==> zero kinetic energy
Highest altitude ==> maximum potential energy
                               ------------------------------------       
Total energy      ==> all potential


Halfway up, halfway down  ( B ) ...

Half-altitude  ==>  half of total energy is potential 
Moving         ==>  some kinetic energy; must be half of total
                          -----------------------------------------
Total energy  ==>  same total; half potential, half kinetic


Lowest point  ( C ) ...

Minimum altitude  ==>  zero potential energy 
Fastest speed      ==>  maximum kinetic energy
                          -----------------------------------------
Total energy         ==>  same total; no potential, all kinetic

The total energy at A, B and C is constant and does not change.

At A, all the energy is potential energy. It gets converted partially to kinetic energy at B and is completely converted to kinetic energy at C. At C, all the energy is kinetic energy.

Potential energy, I’m pretty sure I don’t know but we was learning this in science and this is all I remember that potential energy is the moment energy reaches to a stop...

You weigh 716 newtons on Earth. You
Otrada [13]

Answer:

537 N

Explanation:

The force due to gravity of a planet is:

F = GMm / r²

where G is the universal gravitational constant

M is the mass of the planet

m is the mass of the object

and r is the distance between the object and the center of the planet

On Earth, you weigh 716 N, so:

716 N = GMm / r²

On planet X:

F = G (3M) m / (2r)²

F = 3/4 GMm / r²

F = 3/4 (716 N)

F = 537 N
