Horizontal projectile motion equations Horizontal distance can be expressed as x = V * t . Vertical distance from the ground is described by the formula y = – g * t² / 2 , where g is the gravity acceleration and h is an elevation.

Horizontal distance means the distance between two points measured at a zero percent slope. Horizontal distance means the distance between two points measured at a ((0%)) zero percent slope.

Solution: Choose the formula h = -16t2 + v0t + h0. The initial velocity, v0 = 200 ft/sec and the initial height is h0 = 0 (since it is launched from the ground). Formula: h = -16t2 + 200t + 0.

How to find the maximum height of a projectile?

- if α = 90°, then the formula simplifies to: hmax = h + V₀² / (2 * g) and the time of flight is the longest.
- if α = 45°, then the equation may be written as:
- if α = 0°, then vertical velocity is equal to 0 (Vy = 0), and that’s the case of horizontal projectile motion.

Since the gravitational potential energy of an object is directly proportional to its height above the zero position, a doubling of the height will result in a doubling of the gravitational potential energy. A tripling of the height will result in a tripling of the gravitational potential energy.

The gravitational potential energy of an object is the ‘stored energy’ that the object has by being at that height. This is equivalent to its mass times the force of gravity, g (a defined constant of 9.8 m/s2) times the height of the object. Potential energy = mass x gravity x height.

Gravitational potential energy

GPE is transferred into KE. The KE just before the object reaches the ground will equal the GPE that it loses. An engine causing a car to speed up: The work done by the engine will cause a transfer of chemical energy (of the fuel) into kinetic energy.
