A boy is riding a bicycle in a rainy day. The force exerted by the boy and the force due to which rain falls downward.
To determine the forces acting on the boy riding a bicycle in a rainy day, we need to consider two main forces: the force exerted by the boy and the force due to the rain falling downward.
1. Force exerted by the boy: When the boy pedals and pushes the bicycle forward, he exerts a force on the pedals and the handlebars. This force is known as the propulsive force or the applied force. It is directed in the direction of motion of the bicycle, opposite to the direction of friction. The magnitude of this force depends on the strength and effort applied by the boy.
2. Force due to rain falling downward: The force due to the rain is a result of gravity acting on the raindrops. Gravity is a fundamental force that attracts objects towards the center of the Earth. Since rain is composed of water droplets, each droplet experiences a force of gravity, causing it to fall vertically downward. The force due to rain falling downward is known as the weight of the rain.
It is important to note that the force due to rain falling downward may affect the speed and stability of the bicycle, particularly if the rain is heavy. The rainwater on the ground can also create slippery conditions, making it more challenging for the boy to maintain control of the bicycle.
To summarize, the forces acting on the boy riding a bicycle in a rainy day include the force exerted by the boy and the force due to the rain falling downward. The force exerted by the boy is directed forward, while the force due to rain falling downward is directed vertically downward.
