Yes, you need friction between your feet and the ground. That is caused by gravity or some other attractive force.
It is not exactly known but most likely someone they care about for they would not be singing about her walkiing away if they did not care.
The pull of the Sun's gravity is needed to hold the Earth in orbit.

No, a magnetic field is not needed to create gravity. Gravity is a fundamental force of nature that exists between all objects with mass, whereas magnetism is a different fundamental force that arises from the motion of electric charges.
Weight= mass x gravity Gravity on earth is 9.8 but we use 10
What is the only factor needed to calculate change in velocity due to acceleration of gravity 9.8 ms?
Friction, Normal Force, & Gravity!
fg means fake ground iif somebody comes walkiing iin tha house nnd tha floor brakes that iis called fake ground
He needed gravity because he had ideas about motion. He believed gravity caused planets to revolve around the sun instead of flying off into space.
Gravity is needed for buoyancy as if there was no gravity then there would be no need for buoyancy, the need for buoyancy is to counteract the pull of gravity so you can stay at the surface of a liquid such as water. If there was no gravity then there would be no need to counteract it. I hope this the answer you needed. What if there is a ball of water in space and a cork made dof wood is inserted carefully into the ball. Would it 'rise' from the center of the ball towards the surface or not???
The only factor needed to calculate change in velocity due to acceleration of gravity is time. The formula to calculate the change in velocity is: change in velocity = acceleration due to gravity * time.
I don't know. Tell me for sake Fv= mg is the force needed to counter the force of gravity vertically. Fs = mg sin(a) is the force needed to counter the force of gravity up an incline.
