It is the same force but it is used more efficiently because the strings of the racket are put under tension like springs at the moment of hitting the ball, which with the ball's natural elasticity allows more energy to be transferred to the ball, making it go faster.
Momentum is mass of an object multiplied by its velocity and total momentum is conserved (much like energy). So when the racket hits the ball the amount of
momentum lost by the racket (it was moving with higher velocity during the swing)
is partially (consider mainly the elasticity of the ball and the energy spent on deforming it and the generated heat,sound etc.) gained by the ball causing the ball to have a change in its velocity (in terms of both direction and speed, note that speed is not velocity.) If the ball gets a rotation along with the linear velocity the the linear velocity will be smaller than it otherwise would. If you need to calculate the amount of force excerted on the ball at the time of impact, you need to solve I=integral(P*dt) where the integral is taken from 0 to end of time of impact. And I is basically calculated from (impact) the change in momentum of the racket. Recall though not all of this impact force is gonna be used up by the balls new velocity.
The ball keeps moving forward because of its momentum, which is not a force.
When the ball hits the tennis racket, topspin (preffered stroke of tennis) makes the ball spin. The upward motion of the racket hitting the tennis ball.
No, it's 'these tennis rackets and ball'

It spins when you roll your racket while hitting the ball... In coaching terms, instead of "rolling your racket" you "stroke" or move your racket from point A to B to C. Example: Top spin; point A would be your back swing and usually below the path of the oncoming ball.......point B would be your contact point of the ball.......point C would be stroking forward in an upward direction, thereby imparting top spin on the ball. There is more information on the issue of spin and the material on the face of the paddle at the linked question.

You swing your racket at the ball
Yes, the weight. The lighter the tennis racket, the lighter you hit the ball. The heavier racket can hit harder shots.
A tennis ball
A tennis ball, when impacted, dissipates about 45% of the energy applied to it. This means that it only absorbs and returns 55% of that energy. That is why in the test standard for tennis balls, dropping it from 100 inches, it only rebounds 53 to 58 inches. It is returning that much energy. The strings of the racket, however, return 90% of the energy they are impacted with. So, when the tennis ball hits the strings and they stretch (absorb the energy), they will return 90% of that force in the return of the ball. When a ball hits strings with a higher tension, the force is exerted on the ball, instead of the strings, and the energy return is closer to the 55% range.
