Question

Under what conditions the formulae of range, time of flight and maximum height can be applied directly in case of a projectile motion ?

Answer 1

The formula of range, time of flight and maximum height can be applied directly in case of a projectile motion only when the only external force acting on the projectile is gravity.

We derive the equations for range , time of flight and maximum height by considering that:

• There is no air drag.
• There is no wind or horizontal force.
• There is no other external forces.
• The projectile body moves like a point object.
