Is a force needed to make it bounce back up???
If so, what exerts the force???

The ball acts like a spring. It gets compressed when it hits the ground. Then it decompressess and pushes on the ground to make it go in the air again.

ya , if u drop a ball onto a pavement .
The pavement exerts a reaction force on the ball and makes it bounce back. The reaction force will be in the opposite direction
of initial direction of traversing of the ball ,hence the ball rebounds from the pavement in the opposite direction of the initial direction.

there is an elastic collision that takes place. since the pavement canot be moved at all (the golf ball exerts a force on the pavement and the pavement back to it) the golf ball bounces back due to the conservation of momentum theory.

The pavement does. The ball compresses as it strikes the pavement, and the pressure of the ball on the pavement provides an equal pressure back on the ball. As the compression eases, the ball acquires an upward momentum.

The golf ball is elastic, meaning it can store energy by deformation, like a spring. The kinetic energy of the ball lost when it is stopped is partly stored in elastic deformation, which then propels the ball upward on its release. Some of the kinetic energy is lost to heat, so the ball will not rise as far as it fell.

a golf ball is a soft rubber wrapped around very tightly knit rubber bands.
it's like dropping a basketball thats been pumped up to 15 pounds!
that is a lot of pressure.
