Momentum affect jumping a great deal, that is why a standing long jump is significantly less that one taken at close to maximum speed. Usually the faster an athlete the longer he or she will jump, but jumping also depend not only on speed but also on how the athlete converts that speed in the last couple of strides. A jumper can negate their running speed by slowing down at the board, lengthening the strides at the board or by dropping the hips too low.
Momentum is what (throws) you forward into the jump.

An increase in velocity has a greater effect on momentum than an increase in mass. This is because momentum is directly proportional to velocity, while mass only has an indirect effect on momentum through its influence on velocity.
A team that has the momentum is on the move and is going to take some effort to stop. A team that has a lot of momentum is really on the move and is going to be hard to stop. A sports team which is on the move has the momentum. If an object is in motion (on the move) then it has momentum.
You can reduce its momentum by slowing it down. Fragmenting it - by blowing it up will not reduce the total momentum. However, the effect of each individual piece will be reduced.
You run then jump because you get more momentum and can jump higher. Also, you increase your horizontal velocity so that you can jump farther.
During Track and Field meet, momentum can be observed almost everywhere. Especially in the field events (jumping events and throwing events) where maximizing momentum is the key to performing well. In throwing events such as javelin, shot put, hammer and discus, competitors get to apply force to the object for a brief moment of time. After that, forces acting on the objects are all against the forward motion (i.e. gravitational force, air friction…). At this point momentum is all that is left to keep it going forward.
The two factors that affect an object's momentum are its mass and its velocity. Momentum is calculated as the product of an object's mass and its velocity, so changes in either of these factors will impact the momentum of the object.
An increase in mass will result in a corresponding increase in momentum, assuming velocity remains constant. Momentum is directly proportional to mass, so any change in mass will impact momentum. Conversely, a decrease in mass will result in a reduction in momentum.
Speed directly affects momentum. Momentum is the product of an object's mass and its velocity, so the faster an object is moving, the higher its momentum will be. This means that an object moving at a higher speed will have greater momentum compared to the same object moving at a lower speed.
An athelet always runs before jumping to gain momentum.This helps in jumping higher and longer as the rate of change of momentum becomes less and that is why he can jump higher and longer with the same amount of force.
Momentum = mass x velocity. Therefore, other things (velocity) being equal, momentum is directly proportional to the mass, i.e., more mass --> more momentum.
