when jumping would your time up be the same as down physics

You will soon see that the velocity that the jumper leaves the ground with depends greatly on the speed at which he moves down the runway. There are many changes that can be made to the athlete's technique that will alter these variables in different ways, most of which occur during the run up and take off phases, but do take place at all the different phases, and they all depend on one another.

In order to emphasize the idea of the long jump as projectile motion, it is important to remember that factors such as velocity, height, angle, and time are all going to play a role in the overall distance of the jump. The landing phase occurs when the athlete returns to the ground. The fight phase occurs when the athlete is in the air where the athlete does his best to make sure that he has jumped as far as possible. The take off phase consists of the last few steps of the run up through the point in which the athlete leaves the ground. The run up includes the athletes approach to and travel down the runway. These phases include the run up, the take off, the flight, and the landing (Figure 3). When looking at the long jump, it is most typically divided up into four phases. (Check out the Take Off phase for more information.) Knowing this, we can be sure that the shape of the path of trajectory of the long jumper will be a parabola that is affected by many different variables. We also know for a fact that the vertical velocity of the jumper is always going to be getting more negative.

Since inertia will keep the object moving through the air at a constant rate unless it is acted upon, we know for a fact that the horizontal velocity isn't going to change once the jumper leaves the ground. The force exerted by gravity is -9.81m/s 2.

This means that the acceleration of the motion of the projectile is the the same as the object rises and falls. Because there is no air resistance, gravity is the only force acting on the jumper while he is in the air. This is what we call uniformly accelerated motion (Figure 2). One thing we must know about projectiles before we start is the path that projectiles follow is a prescribed path through the air, if there are no outside forces (such as air resistance or drag) acting on the projectiles.
