Fluid force can affect the trajectory of a javelin by creating drag, which is resistance that opposes the motion of the javelin through the air. The greater the fluid force, the more drag the javelin will experience, leading to a deviation from its intended trajectory. Athletes may need to adjust their technique to minimize the impact of fluid forces on the javelin's flight path.

How much force is put into a javelin?
The force put into a javelin throw varies and depends on the individual's strength, technique, and speed generated during the throw. Elite javelin throwers can generate over 6000 N (around 1350 lbs) of force at the moment of release.
Does the force act on a projectile?
Yes, a force such as gravity acts on a projectile, influencing its trajectory and motion. The force of gravity accelerates the projectile downward, affecting its path and causing it to follow a curved trajectory.
Is air resistance fluid friction?
Yes, air resistance is a type of fluid friction. It occurs when an object moves through the air, causing the air particles to exert a force in the opposite direction of the object's motion. This force opposes the object's motion and can affect its speed and trajectory.
How does applying more force affect the trajectory of the puck when a player is about to shoot it?
Applying more force to the puck when shooting it can cause the puck to travel faster and farther, resulting in a higher trajectory.
What force causes a soccer ball to take a curved path when it is kicked?
The force that causes a soccer ball to take a curved path when it is kicked is called the Magnus effect. This effect occurs when the ball spins as it moves through the air, creating differences in air pressure around the ball that result in a curved trajectory.
