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.
Gravity
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.
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 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.
The only requirement for an object to be in projectile motion is that it must be launched or thrown into the air with an initial velocity. Once in motion, the object will follow a curved path under the influence of gravity, with no additional propulsion.
The motion of an object thrown at an angle is projectile motion. This type of motion involves the object following a curved path due to a combination of its initial velocity and the force of gravity acting upon it. The object moves both horizontally and vertically as it travels through the air.
