Question

• A. Friction between two blocks
• B. Car pushed by a man
• C. Iron nails attracted by magnet
• D. Freely falling ball

Answer 1

The correct option is B

Car pushed by a man

Muscular force is the force applied using parts of the body like arms or legs. It is the force that results due to the action of muscles. It is needed whenever movement of the body occurs.

• Friction between two blocks is as a result of resistance to the relative motion between two objects
• Iron nails get attracted by magnet due to magnetic force
• Objects that are said to be undergoing free fall, are not encountering a significant force of air resistance; they are falling under the sole influence of gravity
• To push a car we need muscular force as in this force is applied by body parts like legs or arms to move the car.
