Jumping off the ground or the ground pushing me up???

http://coach-al.smugmug.com/gallery/4687593_r3cxn#277201461_Xp7DW so here is a picture from coach al's photo smug mug. Because coach al doesnt allow us to copy and paste pictures i have a link instead. As you can see im pretty high up in the air. befre i approached the ball i now realized how relevant it is to NEwtons third Law of motion. As i am getting ready to jump i exert a force to the ground but what i now noticed is that the ground is giving back an equal amount of force that my legs exerted. Thats crazy so now i know if i want to jump higher i need to increase the force exerted by my legs so that the ground force push will aslo increase.

Acceleratorrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrssssssssssss!!!!!!!!

As i was driving on the pali i noticed that my speed was constantly changing. At first i was oblivious to the fact of what was causing my car to accelerate, but than EUREKA! i learned in physics class that there are certain parts of my car that can affect the speed of my car. They are called accelerators which increases the speed and or velocity. They are three accelerators in the car. First off the break pedal, when i press on the break pedal my car decreases in its speed and decreases the velocity. The second acccelerator is the gas pedal when i press my foot on the gas pedal im gone my car speeds up and im as fast as lightining. the third Accelerator is a little tricky it happens to be the steering wheel. The Steering whee when you have to make a turn whether you notice it or not slows down the speed and velocity of the car. Physics is cool man
