According to Newton’s second law of motion:
View all questions of this test
The rate of change of linear momentum is proportional to the applied force, and change in momentum takes place in the direction of applied force.
F = ma
Ft = m(v – u)
A large force acting for a short time to produce a finite change in momentum is called an impulsive force.
Impulse force is the force that acts over a short period of time. Change in the momentum of an object equals the impulse delivered by applied forces.
I = FΔt = Δp
While catching a fast-moving cricket ball, a fielder in the ground gradually pulls his hands backwards with the moving ball. In doing so, the fielder increases the time during which the high velocity of the moving ball decreases. The impact of catching the fast-moving ball is also reduced.
If the ball is stopped suddenly, then its high-velocity decreases in a very short interval of time. Thus, the rate of change of momentum of the ball will be large. Therefore, a large force would have to be applied for holding the catch that may hurt the palm of the fielder.
The conclusion is clear: force not only depends on the change in momentum but also on how fast the change is brought about. The same change in momentum brought about in a shorter time needs a greater applied force. In short, the greater the rate of change of momentum, the greater is the force.

Answer:
The correct answer is option 'B', Newton's second law of motion.
Explanation:
Newton's second law of motion states that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. It can be mathematically represented as:
F = ma
Where:
F = Force applied
m = Mass of the object
a = Acceleration
In the given scenario, the fielder is pulling his hands backwards to catch a fast-moving ball. By doing so, he is applying a force on the ball, which causes it to decelerate and eventually come to rest.
Key points:
- The ball has a certain mass, which can be considered constant in this scenario.
- The fielder applies a force on the ball by pulling his hands backwards.
- As a result of the force applied, the ball experiences an acceleration in the opposite direction to its initial motion.
- The acceleration of the ball decreases as its velocity decreases.
- Eventually, when the velocity of the ball becomes zero, the ball comes to rest in the fielder's hands.
Application of Newton's second law:
In this scenario, the fielder's action of pulling his hands backwards reduces the velocity of the ball. According to Newton's second law, the force applied by the fielder on the ball causes it to decelerate. The force applied by the fielder is directly proportional to the acceleration of the ball. As the ball's velocity decreases, its acceleration also decreases until it reaches zero.
Conclusion:
By applying Newton's second law of motion, the fielder is able to reduce the velocity of the fast-moving ball to zero by applying a force in the opposite direction. This action allows him to catch the ball successfully.
