Jumping involves kinetic friction between your feet and the ground when pushing off and static friction when your feet are in contact with the ground to generate an upward force. Additionally, there is air resistance acting against your movement as you jump.
Friction is not needed on a trampoline for it to function properly. In fact, reducing friction can help improve the bounce and performance of the trampoline by allowing for smoother movements and less resistance.
Friction between the soles of your shoes and the ground allows you to push off and generate the necessary force to jump. The friction provides traction, helping you maintain grip and stability when propelling yourself upward.
When solid surfaces slide over each other, the kind of friction that occurs is called sliding friction. This type of friction results from the resistance to motion between the two surfaces in contact.
Static friction is the type of friction that acts on objects that are not moving. It occurs when two surfaces are in contact but not sliding past each other.
The kind of friction that occurs when solid surfaces slide over each other is called kinetic friction. It is the resistance between the surfaces that are in motion relative to each other.

Sliding Friction
A horse is able to jump because the friction between its hooves and the ground give it traction. Without this it would simply slide around.
This kind of friction is referred to as drag, or air resistance.
Sliding friction requires more force to overcome its friction.
