Friction is the force that opposes the relative motion of two surfaces in contact with each other.
Gravity is the force of attraction between two objects that have mass. It is responsible for keeping objects in orbit around larger bodies, such as planets around the sun.
If there was no friction, objects would continue to move in a straight line at a constant speed, and it would be difficult to stop or change the direction of their motion.
If there was no gravity, objects would float away into space and planets would not be able to maintain their orbits around the sun.
Our daily lives would be drastically different without friction and gravity. We would not be able to walk, drive, or even hold objects without them slipping out of our hands. Many objects, such as buildings and bridges, would not be able to stay in place without the force of gravity. Our entire understanding of physics and the world around us would also be greatly altered.
