hjælp til abstract

hej.

min fagkombination er matematik A-niveau og fysik B-niveau.

mit emne er Det skrå kast med luftmodstand.

her er min abstract:

The purpose of the experiment is to determine the throw of elevation and it is using by a cannon. I will examine the movement of the projectile motion from video recorders. My subject is distributed so it involves of theoretical part and practical part. In the theoretical part, I explain about the projectile motion without air resistance, the particle motion in a parabola, the throw and the height dependence on elevation angle, and finally air resistance with the v2 dependence. In the practical part which I should make an experiment of projectile motion and air resistance. I use a ball and a ping pong ball. The ball and ping pong ball are fired from cannon and simultaneously the time. I examine of the particle path is a parabola, and if air resistance has no effect in the trial and v2-reliance is reasonable. It must be observed through a camera and data program Loggerpro. I make a simulation of projectile motion with air resistance and compared with the theory of air resistance. I have to study of the particle path is a parabola, and if air resistance has no effect in the trial and v2-reliance is reasonable. My theory and practical are almost together but there is not a very big difference. A particle with friction has a smaller distance then for a particle without friction. Friction has a large dependence on speed.

please kommenter ALT om hvilke fejl der er osv.

jeg er hellere ikke lige den bedste til engelsk.

på forhånd tak.
