The time of flight in projectile motion is the total time that an object is in the air after it is launched. This time is a very important part of projectile motion problems and is very vital for MDCAT students as it forms a crucial part of the physics section of the exam. The concept of how to find the time of flight is very important in solving problems involving horizontal range, maximum height, and other characteristics of motion. The time of flight depends on the initial velocity and the angle of launch, which determine how long the projectile stays in the air.
Calculating Time of Flight in Projectile Motion
The time of flight can be found using the vertical component of the motion, since gravity is the only force acting in the vertical direction. The total time of flight

). The factor of 2 accounts for the time taken to reach the highest point of the trajectory and then descend back to the ground. MDCAT students must understand this formula to apply it when solving projectile motion problems, allowing them to calculate the duration of time the object remains in motion.
MDCAT Quiz: Time of Flight Questions
This type of question is common in the MDCAT Quiz: projectile motion problems often ask how long a projectile is in the air. Some questions may be given with the initial velocity or launch angle or any other parameter, asking students to find the time of flight. For example, a common type of question could ask how long a ball is in the air when launched at a certain angle and with a specific initial speed. Only through proper decomposition of the motion into its vertical and horizontal components, along with the application of the appropriate formula, can such a question be answered correctly.
