Question
“The sum of momenta of the two objects before collision is equal to the sum of momenta after the collision provided there is no external unbalanced force acting on them.” This statement belongs to:
- Law of conservation of momentum
- Law of conservation of acceleration
- Law of conservation of velocity
- Law of conservation of mass
Hint:
- The law of conservation of momentum states that the sum of momenta of the two objects before collision is equal to the sum of momenta after the collision
The correct answer is: Law of conservation of momentum
- The law of conservation of momentum states that the sum of momenta of the two objects before collision is equal to the sum of momenta after the collision
