A ball is tossed straight up from the surface of a small spherical asteroid with no atmosphere. The ball goes to a height ewual to the asteroid's radius and then falls straight down towardd the surface of the asteroid. What forces if any act on the ball while it is on the way up?

a) only a decreasing gravitational forces acts downward
b) Only an increasing gravitational gorce that acts downwards.
c) only a constant gravitational gorce that acts downwards
d) Both a constant gravitational foce that acts downwards and a decreasing force that acts upwards.
e) No foces act on the ball

With there being no atmosphere would g be contant thus the answer is c) or is the answer d)?

g is NOT constant, either there or on Earth. g depends on the inverse distance squared from the center. As one gets more altitude, g decreases. In any case, the force is "downward", or attractive.

a. Only decreasing gravitational force acts on the ball.

First of all, let me just say that the concept of a ball being tossed on a small spherical asteroid with no atmosphere is quite comical! But let's get to the question.

While the ball is on its way up, the only force that acts on it is a constant gravitational force that acts downwards. So, the correct answer is c) only a constant gravitational force that acts downwards.

Now, I must clarify that the force of gravity does indeed decrease as the ball goes higher because gravity depends on the distance from the center of mass. So, option d) would also be correct, which includes a decreasing force that acts upwards.

But hey, who needs to complicate things? It's a ball on a little asteroid, not a rocket launch! So, let's stick with the simple answer - a constant gravitational force acting downwards.

Hope that clears things up for you, and remember, even in the vastness of space, humor can always find its way!

The correct answer is d) Both a constant gravitational force that acts downwards and a decreasing force that acts upwards.

When the ball is on the way up, the only force acting on it is the gravitational force, which is constant and acts downwards. This force causes the ball to accelerate in the upward direction, slowing it down as it moves higher. As the ball reaches its peak height, the gravitational force is still acting on it, but now in the downward direction.

Additionally, there is a decreasing force acting upwards as the ball moves higher. This force is caused by the gravitational attraction between the ball and the asteroid. As the ball moves away from the center of the asteroid, the distance between the ball and the center decreases, resulting in a decrease in the gravitational force. This upward force opposes the gravitational force acting downwards.

Therefore, the ball experiences both a constant gravitational force that acts downwards and a decreasing force that acts upwards while it is on the way up.

The correct answer is d) Both a constant gravitational force that acts downwards and a decreasing force that acts upwards.

When the ball is on its way up, there are two forces acting on it. The first force is the constant gravitational force that acts downwards towards the surface of the asteroid. This force is always present and is responsible for pulling the ball towards the center of the asteroid.

The second force is an upwards force that is decreasing as the ball moves higher. This is due to the fact that as the ball moves away from the surface of the asteroid, the distance between the ball and the center of the asteroid increases. According to the law of gravity, the force of gravity decreases with increasing distance. Therefore, as the ball moves higher, the force pulling it downwards also decreases.

So, to summarize, while the ball is on its way up, there is a constant gravitational force acting downwards and a decreasing force acting upwards.
