Why is the gravitational potential energy of an object 1 meter above the moon’s surface less than its potential energy 1 meter a

dsp73

Potential energy relative to the surface is

(mass) x (acceleration due to gravity) x (height above the surface).

At 1.0 meter above the surface, that is

 (mass) x (acceleration due to gravity) x (1.0 meter) .

The object's mass doesn't change, so the only thing that has any effect
on its potential energy at 1 meter above the surface is the acceleration
of gravity or, in other words, the surface of what ?

Barry slides across an icy pond. The coefficient of kinetic friction between his

Soloha48 [4]

The force of friction acting on him is 122 N. The correct answer is option C

<h3>What is Friction ?</h3>

Friction is a force that opposes the motion of a static or a moving object.

Given that Barry slides across an icy pond. The coefficient of kinetic friction between his shoes and the ice is 0.15. If his mass is 83 kg

The given parameters are;

Mass m = 83 kg

Coefficient of kinetic friction μ = 0.15

Frictional force $F_{r}$ = ?

The normal reaction N on the body = mg

N = 83 x 9.8

N = 813.4 N

The Frictional force formula is $F_{r}$ = μN

$F_{r}$ = 0.15 x 813.4

$F_{r}$ = 122.01 N

Therefore, the force of friction acting on him is 122 N approximately.

pishuonlain [190]

Answer:

when the ball is at its highest in the air.

Explanation:

I don't know for sure, but when the ball is in the air it has potential energy to fall(or something like that).
