Enter the velocity and the initial height of an object in projectile motion to determine the total time of flight and total distance covered.

Horizontal Projectile Motion Formula

The following equations are used by the calculator above to determine the time of flight and distance of an object in horizontal projectile motion. As an object in projectile motion, the time of flight is only determined based on the initial height and the force of gravity.

t = √(2 * h / g)
  • Where t is time (s)
  • h is the height (ms)
  • g is the acceleration due to gravity = 9.8 m/s^2

With time solved for using the equation above, the distance traveled by an object in the horizontal direction can be easily calculated using the following formula.

x = V * t
  • Where x is the horizontal distance (m)
  • V is the velocity (m/s)
  • t is time (s)

Horizontal Projectile Motion Definition

Horizontal projectile motion is defined as an object that is moving horizontally under only the force of gravity and velocity.

How to calculate time of projectile motion?

How to calculate the time of projectile motion

  1. First, determine the maximum height of the object.

    This is often the height the object is launched from.

  2. Next, use the formula to calculate the time of flight.

    Using the formula above, you can enter the height to determine the time of flight.


What is projectile motion?

The projectile motion describes the motion of an object that is launched into the air at a constant velocity and angle. The trajectory of that object is determined by these initial values and the force of gravity.

What affects the time in the air of a projectile?

The y component of the velocity is the only factor that determines the time in the air since gravity works in the y-direction.
