Question

When we kick a stone, we get hurt. Due to which of the following properties of the stone does it happen?
A) Inertia
B) Velocity
C) Reaction
D) Momentum

Answer 1

Hint: The newton’s third law of motion explains about the action and its opposite reaction. For every action there will be the equal and the opposite direction. In the given question, the reactive force depends upon the provided force and the weight of the stone.

Complete step by step solution:
When the stone is kicked by the leg, the force provided by the body is exerted on the stone. But due to the law of the conservation of the movement, there will be the reactive force against the force provided by the body. This is because, every force has the equal and the opposite reactive force against it. This causes the pain provided by the stone to the leg causing hurt. But the other options given in the questions, inertia is the inability of the body to change its state of motion by itself. And velocity is the rate of the change of the displacement of the body. The movement is the process of movement.

Thus the option (C) is correct.

Note: The other example of the newton’s third law of motion, is firing of the gun. While firing the gun, the bullet is fired to the environment, during which the bullet moves forward, but due to the reaction, the gun moves backward providing the jerk to the body.
