If placed in water Saturn would float. This is because it is mostly made up of gas, which is less dense than water.
W= 540 N
M=?
G= 9.8
W=mg
540=mx9.8
M=540\9.8
M=55.10
Answer:
<u>Gravitational Force</u> is a force that attracks two objects with mass. For example, you are being pulled onto this planet, and that's why when you jump upwards, you fall back down quickly. A fun fact is that every object, even the entire universe, are pulling all on each other, including you!

The magnitude of the acceleration in the y-direction is
Explanation:
When a projectile is fired into the air, there is only one force acting on it (neglecting air resistance): the force of gravity, which pulls the projectile downward with a force of
F = mg
where m is the mass of the projectile and is the magnitude of the acceleration of gravity. This force acts along the y-direction, downward.
Since there are no other forces acting, therefore, the motion of the projectile consists of two separate motions:
- A uniform motion along the x-direction, with constant velocity
- A uniformly accelerated motion along the y-direction, with constant acceleration ()
So, the magnitude of the acceleration in the y-direction is .
