The model makes it possible to better understand the motion of a body under the action of gravity with an initial impulse — a classical problem in ballistics.

Two bodies are attracted with forces proportional to the product of their masses. The body in the Earth's field is affected by gravity, which is the product of mass and gravitational acceleration equal to 9.8 m/s². If the air resistance is not taken into account, then a body launched at an angle to the Earth's surface will move along the surface without acceleration, and perpendicular to the surface — with an acceleration of 9.8 m/s².

By controlling the angle of the gun and the magnitude of the initial impulse, study how the trajectories of the model projectile change.
