Why is it easier for a car to travel in going down than in going up the slope?
Because all objects are attracted toward the center of the Earth due to gravity.
Because of the magnetic force that magnetized the car to go down easier.
Because the car becomes heavier when moving up than going down.
Because the frictional force causes the car harder to moves up.
How can you best reduce friction between the bottom furniture and the floor?
by smoothing the floor
by keeping furniture on their place
