Gravity
An object is in projectile motion if it is only under the influence of gravity and air resistance is negligible. The object follows a curved path called a projectile trajectory. The motion can be broken down into horizontal and vertical components.

Throwing a baseball Kicking a soccer ball Shooting an arrow with a bow These are all examples of projectile motion where an object is launched into the air and moves along a curved path under the influence of gravity.
Both projectile motion and circular motion involve the motion of an object in a curved path. In projectile motion, the object follows a curved path due to the influence of gravity, while in circular motion, the object moves in a circle with a constant radius. Both involve centripetal acceleration that changes the direction of the object's velocity without changing its speed.
Two-dimensional motion that is not always projectile motion would be circular motion, where an object moves in a circular path. Two-dimensional motion that is not projectile motion and does not accelerate the object could be uniform circular motion, where the speed is constant but the direction changes.
Actually, an object being swung in circles on the end of a rope is an example of circular motion, not projectile motion. Projectile motion refers to the motion of an object that is launched into the air and then moves under the influence of gravity. Circular motion involves an object moving in a circular path around a fixed point.
Gravity would be pulling down on a projectile object.
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.
No, an object sliding along a horizontal table is not an example of projectile motion. Projectile motion occurs when an object is launched into the air and follows a curved trajectory under the influence of gravity. A sliding object on a horizontal surface does not follow a curved path in the air.
Projectile motion involves an object moving both horizontally and vertically, while free fall is when an object falls only vertically due to gravity. In projectile motion, the object has an initial horizontal velocity, while in free fall, the object is only affected by gravity.
A projectile motion graph illustrates the path of an object in motion, showing how its position changes over time. It typically shows the object's vertical and horizontal displacement, velocity, and acceleration as it moves through the air.
