Gravity
The downward force acting on an object in free fall is Gravity.
If we neglect the effect of air resistance, an object is accelerating toward the ground at 9.8 m/s^2. When you determine an object's weight, you multiply its mass by this number. My point is that weight is the downward force on an object.
Force = mass X acceleration = mass X change in velocity If there was no force pointing upward, the only force acting on the object would be gravity, and it points down. From the equations above it should be easy to see that if the only force acting on an object was pointing downward, the object would move downward, and if the force was gravity, it would fall downwards through water similar to how it would in air.
The force that opposes a downward force on an object would be called the "normal force". For example, it is as a result of the normal force that people do not fall though the ground the same way that they fall through the air.
No. When an object is in free fall it has a downward force (it's mass) and an opposite, upward force of air resistance.

Gravity.
When the only force on an object is the force of gravity,we say that the object is in "free fall".
An object in free fall is one that has only the force of gravity acting upon it.
free fall
Gravity.
well if you think about it free fall is just an object that falls down with no force besides gravity pushing on it. and projectile is also something or an object that has no force acting on it besides gravity. so there pretty alike. that is how they compare.
