Question

Which of the following real life examples does not involve the use of muscular force?

• A. Kicking a football
• B. Squeezing a sponge ball
• C. Breathing in and out
• D. An apple falling on the ground from a tree

Answer 1

The correct option is D An apple falling on the ground from a tree

The force resulting due to the action of muscles is known as muscular force.
In all the examples except that of an apple falling on the ground, our muscles are involved to bring the desired change in the state of motion of the body. However, an apple falls on the ground because of gravitational force.
