frictional are always act in direction of motion
frictional are always act in opposite direction of motion
Direction of force of friction is always in the same direction of motion.
Which of the following statements are true in the real world scenario?
Statement 1: A uniform motion requires no net force.
Statement 2: In practical situation friction force is always zero.
Statement 3: Friction force acts opposite to the direction of relative motion.
Statement 4: Frictional force can be minimized by using rough surface.
