On Earth, all free-falling objects have an acceleration g due to gravity, which averages g = 9.81 m/s^2. For objects in free fall, the upward direction is normally taken as positive for displacement, velocity, and acceleration.

(a) Calculate the height at which the shell explodes. (b) How much time passes between the launch of the shell and the explosion? (c) What is the horizontal displacement of the shell when it explodes? (d) What is the total displacement from the point of launch to the highest point?

The acceleration due to gravity gives rise to a common (non-SI) unit of acceleration, also called the g :

Whether ...An object in free-fall experiences constant acceleration if air resistance is negligible. On Earth, all free-falling objects have an acceleration due to gravity g, which averages g=9.80 m/s2. Whether the acceleration a should be taken as +g or −g is determined by your choice of coordinate system. Since acceleration is constant, the kinematic equations above can be applied with the appropriate +g or −g substituted for a. For objects in free-fall, up is normally taken as positive.

In the absence of air resistance, is the cliff diver’s acceleration 9.81 m/s 2 in the simulation below? At any given location on the Earth and in the absence of air resistance, all objects fall with the same uniform acceleration. We call this acceleration the acceleration due to gravity on the Earth and we give it the symbol g.
