An object in free fall has no velocity in the x direction, it is falling straight down. A projectile however does have some x velocity but it is constant, there is no acceleration in this direction. The only acceleration of the object is in the y direction and it is equal to the acceleration due to gravity. When doing calculations for a projectile object you can use all the same equations as for an object in free fall but you have to apply it to both axis of motion, x and y.

Dropping an object under the influence of gravity is a launch. The object becomes a projectile at the moment of release. It is only free fall in a total vacuum.

Free fall is an object moving with only the force of gravity. Projectile has a force acting on it other than gravity pushing it in some direction or directions.

A projectile can move away from the Earth but something that is dropped from a height can't. Unless the projectile is moving at escape velocity it will eventually stop and start moving back towards the Earth.

No massive distinction rather. loose fall is modern-day throughout projectile action too. yet oftentimes , loose fall questions relate with a physique falling vertically down, that's at no attitude with gravity. on the same time as in case of projectile action , the physique travels at some attitude with admire to the gravitational rigidity (that's vertical close to the exterior , it surely directs to the midsection of the planet). wish this facilitates.

A projectile is a free falling object by definition, once it has left whatever initially propelled it, it is only under the influence of gravity.

you kick a ball = projectile
you drop the ball = free fall

a projectile has an initial forward velocity

'Free fall' is dropped and 'projectile' is launched.
