What's given in the problemThe motion is one-dimensional.The motion occurs when a person walks or a car moves along the road.Helpful informationHorizontal motion:Movement along a straight line on a horizontal plane.Vertical motion:Movement along a straight line on a vertical plane.Projectile motion:Movement of an object launched into the air, following a curved path due to gravity.Momentum:A measure of an object's mass in motion.How to solveDetermine which type of motion best describes movement along a road or ground.Step 1.Identify the correct type of motionThe motion is along a straight line on the ground.This is horizontal motion.Vertical motion involves movement up or down.Projectile motion involves a curved path.Momentum is not a type of motion.SolutionThe motion is horizontal motion.
