Does the force of gravity acting on a ball change as the ball is thrown straight up from the surface of the earth?
To be absolutely technically accurate, yes. The gravitational force between the earth and the ball
is inversely proportional to the square of the distance between the center of the ball and the center
of the earth, so it decreases as the ball moves away from the center of the earth.
We don't normally notice the effect in our every-day ball-throwing experience, because it's so small ...
a ball tossed from sea-level 50-ft straight up loses about 0.0005% of its weight.
(A 200-pound man at 26,400-ft/5-miles altitude becomes about 8 ounces lighter, compared to sea level.)
What else can I help you with?
When a ball is tossed straight up it momentarily comes to a stop at the top of its path Are there any forces acting on the ball at this point?
Yes. If there weren't, it would stay up there. The force of gravity acts on the ball ALL of the time, and once the ball leaves your hand, the force of gravity controls the motion of the ball.
Does your weight change depending on the pull of gravity?
Yes, weight is a measure of the force of gravity acting on an object. Therefore, weight will change depending on the strength of the gravitational pull, which can vary depending on location (e.g., Earth's gravity vs. the moon's gravity).
When the amount of gravity increases what happens to the mass of an object?
The mass of an object does not change when the amount of gravity acting on it increases. Mass is an intrinsic property of an object and remains constant regardless of the strength of gravity.
Is it true that the weight of an object changes if the force of gravity changes?
Yes, weight is directly proportional to the force of gravity acting on an object. If the force of gravity changes, the weight of the object will also change accordingly.
Does your weight change if the acceleration due to gravity changes?
Your weight is determined by the force of gravity acting on you, so it will change if the acceleration due to gravity changes. If the acceleration due to gravity increases, your weight will increase, and if it decreases, your weight will decrease.
What is normal force?
Normal force is the force of a surface acting on an object( the normal force is perpendicular to the plane of contact). This force is directly related to the force of gravity, as the third law of newton state that when a force is applied to an object it will react with an equal force in the opposite direction. So when an object is placed on a surface, the force of gravity is acting on it (pulling it down), but the is object remain in place due to the normal force (which is pulling up on the object). In addition, a change to the force of gravity will result in the same change to the force of normal, to allow an object to remain stationary.
How would the motian of the moon change if there where no gravity?
The motion of the Moon would change from an elliptical orbit to a straight line.

Yes. If there weren't, it would stay up there. The force of gravity acts on the ball ALL of the time, and once the ball leaves your hand, the force of gravity controls the motion of the ball.
How does the gravity of mars vary with its mass?
-- If the mass of Mars increases, then its surface gravity also increases. -- If the mass of Mars decreases, then its surface gravity also decreases. -- So long as its radius does not change, the acceleration due to gravity on or near the planet's surface is directly proportional to its mass.
How do glaciers form and change the earth's surface?
by gravity, ice, wind, water

What effect does gravity have on velocity?
Gravity changes the velocity of an object that is in "free fall" (that is, one that is only subject to the force of gravity). Near Earth's surface, this change of velocity due to gravity occurs at a rate of 9.8 (meters / second) / second; usually this is written as 9.8 meters/second2.
Objects moving at a constant speed in a straight are said to be in?
Objects moving at constant speed in a straight line are said to be in equilibrium. That is there is no force acting on them. If a force was acting there would be aceleration and the velocity would change.
Can gravity on earth change?
Yes, definitely. If a substantial piece of the Earth were to break off and sail away,then the force of gravity on the surface of the remaining piece would be substantiallyless than it is now.As long as the Earth's mass doesn't change substantially, however, the accelerationof gravity on or near its surface, and therefore the weight of things located in thatneighborhood, doesn't change.
