As soon as it is launched, a projectile is in free fall.
False Because gravity is constantly pulling on the projectile while the projectile is trying to move forward in a straight line, the projectile will move in a CURVED path and fall down to earth.
Free fall
Given no air resistance or other forces acting on the projectile, the projectile falls at a rate of ~9.81 meters per second. Given the position equation is at^2 + vt + x, where a is acceleration, v is velocity, x is the starting position, and t is time. Given an initial velocity and time of zero, the object will have moved ~9.81 meters in the first second.
c. Free fall
free fall
A projectile has an initial forward velocity.
A projectile has an initial forward velocity.
The initial velocty of a projectile is non-zero.
A projectile has an initial forward velocity.
It is a projectile falling with an acceleration equal to that of free fall. (an object falling in a vacuum at the earth's surface)
They're equal.
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.

They are the same, if the effect of air resistance is ignored.
The fall of a projectile is due to the force of gravity. Projectiles have no capacity for self-propulsion and are objects that are thrown or propelled.
A projectile kit is a device being used in showing the motion of a free-falling body and a projectile. It is clamped on one corner of a table and uses 2 marbles. It is also accompanied by metal sheets - one for the FFB and for the projectile. When you use it, you may notice that when the two marbles were launched. It will fall at the same time (you can hear a single sound).
c is correct.
