Question
A man pushes a trolley as shown in the diagram. Force A pushes the trolley forwards, while force B pushes against the trolley to oppose the motion.Classify the two forces.A is tension, B is gravityA is applied, B is gravityA is applied, B is air resistanceA is friction, B is applied
Solution
The correct classification of the two forces would be "A is applied, B is air resistance".
Here's why:
Force A is an applied force because it is the force exerted by the man to push the trolley forward. Applied force is the force that is applied to an object by a person or another object.
Force B is air resistance because it opposes the motion of the trolley. Air resistance is a type of friction that acts against the direction of motion as an object moves through air.
