it hits almost a lot of force that the under ground starts shaking like if it was a earth quick. [but it really does not feel like that to the people that are running they just get tired
Compression.
In order to lift a 270 kg, which is about 596 pounds rock one foot off the ground you will need a forklift or other weight lifting machinery. A normal person will not be able to lift a rock that heavy on their own.
you have decreased the area over which the force is applied, and pressure is force per unit area
There are several forces involved while riding a skateboard. The force of friction (air resistance and contact with ground) acting against the motion and the pushing force from when you push off with your foot acting with motion. There are also several normal reaction forces, the weight of the person on the skateboard and the weight of the skateboard on the ground.
1) While the ball is kicked, the main force is the force of the foot against the ball.2) While the ball is in the air, the main force acting on the ball - again, an unbalanced force - is gravity.
Well, if you don't push down the normal force will not push back.
Compression.
6 on each foot
Yes. Of course, the ground exerts an equal-abd-opposite compressive force on you.===========================Answer #2:Experiment:-- Place a raw egg between the ground and your foot.-- What did you observe ? Was there any evidenceof a compressive force anywhere ?
...he exerts against the ground
Yes; a running athlete can exert up to 4 times their body weight in force upon the ground.

by applying force to the ball the ball will apply an equal and opposite force on the foot. when you kick the ball, the ball will move forward and your foot will move backward. this force is unnoticeable to the common person simply because we are not looking for it
you have decreased the area over which the force is applied, and pressure is force per unit area
Newton's 3rd law of motion states is basic terms that for every action there is an equal, but opposite reaction (if you push against a wall with force F, then the wall will push back with force -F). When you walk/run forward, you exert a force on the ground that goes diagonally down and backward. The equal, but opposite reaction is the ground exerting a force on your foot that is diagonally up and forward (exactly opposite that applied by your foot). This helps to propel you forward as you walk or run.
Ten, five on each foot.
