Suppose an object is located in deep space, far away from any gravity. Would a force need to be applied in order to accelerate t

he object in space, or would there be no need for a force to make it accelerate?

Answer:

Force will be needed to make the object move

Explanation:

An object at rest will stay at rest and an object in motion will stay in motion unless acted on by an unbalaced object.

An undiscovered planet, many lightyears from Earth, has one moon in a periodic orbit. This moon takes 1760 1760 × 103 seconds (a
Katen [24]

Answer:

a_c=6.471\frac{m}{s^{2}}

Explanation:

We can calculate the magnitude of the tangential velocity of the moon, using the equation:

v=\frac{2\pi R}{\tau}

(This works, since velocity is defined as distance over time; in this case the distance is 2πR and the time is the period τ)

Next, from the equation of the centripetal acceleration we have:

a_c=\frac{v^{2} }{R}\\\\a_c=\frac{4\pi^{2}R}{\tau^{2} }

Be careful, the radius of the orbit R is equal to the distance from the center of the moon to the center of the planet. So we have to sum the distance from the center of the moon to the surface of the planet and the radius of the planet to obtain R:

R=285.0*10^{6} m+3.50*10^{6} m=288.5*10^{6}m

Finally, plugging the given values into the centripetal acceleration formula, we have:

a_c=\frac{4(3.141)^{2}(288.5*10^{6}m)}{(1760*10^{3}s)^{2}} =6.471\frac{m}{s^{2}}

In words, the moon's radial acceleration a_c is 6.471m/s².

Why does New and Full moons produce stronger tides.
serious [3.7K]
Because at the time of New and Full moons, the Earth, Sun,
and Moon are all lined up on the same line.  So the effects
of the Sun and Moon combine to influence the tides in the
same direction.

The acceleration due to gravity on the moon is 1.6 m/s2. What is the gravitational potential energy of a 1200-kg lander resting
faltersainse [42]

Gravitational potential energy is energy an object possesses because of its position in a gravitational field. The equation for gravitational potential energy is GPE = mgh. 


GPE = 1200(1.6)(350) = 672000 J


Hope this answers the question. Have a nice day.
