Question

Describe three factors those affect the trajectory of a projectile.

Hint:

In sports like Shot Put, where the release point is higher than the landing point, the optimal angle is actually slightly less than 45° (around 37°–42°).

Answer 1

Step 1: Understanding the Concept: 
A projectile is any object thrown into space upon which the only acting force is gravity. Its path (trajectory) is parabolic. 

Step 2: Detailed Explanation:  
 

1. Angle of Projection: The angle at which the object is released. For maximum horizontal distance (range), the ideal angle is 45° (assuming release and landing heights are equal).
2. Initial Velocity: The speed at which the object is thrown. Higher initial velocity results in a longer and higher trajectory.
3. Gravity: Gravity pulls the projectile downward, causing the vertical component of the velocity to decrease. It is the force that turns a straight path into a curve.

Step 3: Final Answer: 
The trajectory is influenced by the angle of release, the speed of release, and the force of gravity.
