Incorrect Statement:
a) friction acts on a ball rolling along the ground
Friction does act on a ball rolling along the ground. When a ball is in contact with the ground, there is friction between the ball and the surface it is rolling on. This friction helps to slow down the ball and eventually bring it to a stop.
b) friction acts on a boat moving on water
Friction does act on a boat moving on water. When a boat moves through water, there is friction between the hull of the boat and the water. This friction helps to propel the boat forward and also affects its speed and maneuverability.
c) friction acts on a bicycle moving on a smooth road
Friction does act on a bicycle moving on a smooth road. When a bicycle is in motion, there is friction between the tires of the bicycle and the road surface. This friction provides the necessary traction for the bicycle to move forward and also helps in maintaining stability while riding.
d) friction does not act on a ball moving through air
This statement is incorrect. Friction does act on a ball moving through air, although it is less noticeable compared to friction on solid surfaces like the ground or water. As the ball travels through the air, it experiences air resistance, which is a form of friction that opposes its motion. This air resistance affects the speed and trajectory of the ball, making it slow down and change direction.
