Believe it or not ,a spiked grave vase.I'm not kidding.
When we walk on the ground our foot pushes the ground backward, and in return, the ground pushes our foot forward. The forward reaction exerted by the ground pushes our foot forward. The forward reaction exerted by the ground on our foot makes us walk forward.
when we walk on the ground, our feet pushes the ground in backward direction, as a reaction ground pushes us in forward direction hence we can walk on the ground.
The force that pushes up on you when you jump vertically off the ground is called the normal force.
a soak allows water to gradually enter the ground . it absorves WATER , FILTERS IT AND PUSHES IT INTO THE GROUND . THIS INCREASES THE LEVEL OF GROUND WATER
The energy from the fuel pushes against the ground, which (because every action has an equal and opposite reaction) pushes the rocket up.
...he exerts against the ground
they have weight that pushes the ground and they have to use balance
The propellant
The force to keep us and nearly everything else on the ground is GRAVITY.
you need friction so the ground can push on your foot while your foot pushes on the ground. that is the only way you can move.
When the skateboarder pushes on the ground with her foot, she exerts a force on the ground in one direction, causing the ground to exert an equal and opposite reaction force on her in the opposite direction. This reaction force propels the skateboard and the skateboarder forward, resulting in acceleration down the sidewalk.
The force that pushes you up is normally gravity acting on your body. When you jump, your leg muscles exert a force on the ground, propelling you upwards against gravity.
