Question

It is easier to stop a tennis ball than a cricket ball moving with the same velocity. This is because:
A. Tennis ball has less momentum than cricket ball
B. Tennis ball is soft and offers less friction
C. Cricket ball is hard and offers more friction
D. None of these

Answer 1

Hint:Here we have to apply the concept of Newton’s second law of motion.The second law of motion of Newton pertains to the actions of objects with which not all current forces are balanced. The second law notes that two factors-the net force acting upon the object and the mass of the object-depend on the acceleration of an object. An object's acceleration depends directly on the net force acting upon the object, and inversely on the object's mass.

Complete answer:
Momentum is a concept in physics; it refers to the amount of motion an object has. The momentum is given by a sporting team that is on the move. If a thing is in motion (on the move), it would have momentum.

The momentum 's path is the same as that of the velocity. The more momentum there is with an object, the harder it is to stop. Two factors depend on the amount of energy an object has: how fast stuff moves and how easily the stuff moves. Momentum depends upon the mass and velocity of the variables.

The momentum of an object, in terms of an equation, is proportional to the mass of the object times the object 's velocity. A body shifts only when a force of a certain magnitude is applied to it in a certain direction. If an opposing force of equal size is applied to it, the moving body may be halted.

A running tennis ball 's mass is smaller than that of a cricket ball moving at the same pace. The tennis ball thus has less momentum than the cricket ball, which makes it easier to avoid a tennis ball than a cricket ball going at the same pace. It provides more friction as well.

Hence, option A is correct.

Note:An object's momentum is directly proportional to the mass and velocity of the object: if the mass and or velocity increases, the momentum increases by the same amount. And the momentum will decrease by that amount if mass and or velocity is decreased.
