Is the force of gravity on a projectile in motion is considered positive.?
false
Is the force of gravity on a projectile considered positive?
In physics, the force of gravity is typically considered a negative force because it acts in the opposite direction to the motion of the projectile. Gravity causes the projectile to decelerate and move downwards.
Is a feather falling in a vacuum projectile motion?
No, a feather falling in a vacuum is not considered projectile motion. Projectile motion involves an object being launched horizontally with a certain velocity while experiencing the force of gravity, causing it to follow a curved path. In a vacuum, there is no air resistance or drag force acting on the falling feather, so it falls straight down due to gravity.
Why gravitationalforce is taken negative in projectile motion?
Gravitational force pulls downward. If you take the upward direction as positive, then any force that pulls downward will be negative. It is a matter of definitions; you can just as well define up as negative, and down as positive. It doesn't really matter much, one way or the other.
Is projectile motion a motion in one dimension the direction of gravity?
No, projectile motion involves motion in two dimensions - one horizontal and one vertical. The vertical motion is affected by gravity, while the horizontal motion is independent of gravity, assuming no air resistance.

How does the gravity affect the two components of projectile motion?
Projectile motion has two components horizontal motion and vertical motion. Gravity affects only the vertical motion of projectile motion.

Which part of projectile motion is affected by gravity?
The vertical motion of a projectile is affected by gravity. Gravity acts to accelerate the projectile downward while it is in motion, causing its vertical velocity to increase or decrease accordingly.
The height of a projectile in motion is dependent on what?
Projectile motion is a form of motion wherein an object moves along a curved path under the action of gravity only. The height of a projectile in motion is dependent on gravity.
Is a ball on the ground a projectile?
No, a ball on the ground is not considered a projectile. In physics, a projectile is an object that is in motion and is only subject to gravity and air resistance. A ball on the ground is not in motion and is not being acted upon by external forces.
The work done by gravity during the descent of a projectile motion is?
Zero, assuming there is no air resistance. Gravity does not do work in the horizontal direction during the descent phase of projectile motion because the force of gravity and the displacement are perpendicular to each other, resulting in no work being done by gravity.
Why you take g as negative in projectile motion?
it depends on what direction you take as the positive axis in a X,Y direction. if you say positive(X) is away from the earth then you would say gravity(g) is pulling the projectile the opposite direction from positive (X). if you say positive (X) is towards the center off the earth than you could say (g) is going with the (X) so g would end up positive. in summary is depends on how you set up the X,Y axis compared to the problem you are solving.
Two dimensional motion is not always projectile motion . in two -dimensional motion that is not projectile motion , ____ is not accelerating the objective?
Gravity
