Inertia of Moving Objects

A man jumping from the trampoline has a vertical velocity upwards.
Since the Trampoline is on a huge speeding truck say 40 km/hr, when the man leaves the trampoline, he will also have the same initial speed of 40 km/hr in horizontal direction.

Man lands safely on the trampoline even though he got separated from it. This is because of the fact that he was also moving with the same speed as the truck. Inertia of moving objects. There may have been some air resistance to slow him down compared to the speed of the truck. So I guess they must have done this stunt at lower speeds to keep the air resistance or drag of the man as low as possible.

Also observe a beautiful sight that, for a person standing on the trampoline the man feels like he is going up and then comes down. For a person observing from the ground, the visuals show very nicely that the man is moving both in vertical direction and also in the horizontal direction, taking a parabolic path, like a Projectile motion.
We say with respect to the truck the man is having only linear velocity in vertical direction. With respect to the ground reference, meaning somebody watching from the ground, the man would take a projectile motion or parabolic path.

The truck is moving at a constant velocity not accelerating, so the truck is still an inertial frame of reference and not an accelerating frame of reference. If the truck have been accelerating, then the truck would have gone past the man who would still be travelling in the same horizontal speed when he left or jumped from the truck, which could have been a fatal situation. (I like to think of it as Acceleration does not have memory, velocity has memory. Newton's First Law.)

This also clearly confirms and helps us visualize the projectile motion concepts that the motion in the X direction and Y direction happen simultaneously without affecting each other.

What is Projectile motion? 
Motion in a projectile is a combination of movement in the X and Y directions simultaneously.





Galileo's Law of Projectiles

(Seemingly complicated Projectile Motion problems are very easy once 
you tackle them as two different motions happening in X and Y directions
at the same time.)
