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 provided there is no external unbalanced force acting on them. ”Is the statement true or false?

The velocity after and before collision is same. Is the statement true or false?

1. True    
2. False    

What is being depicted in the image:

1. Law of conservation of momentum    
2. Law of conservation of acceleration    
3. Law of conservation of velocity    
4. Law of conservation of mass    

What is missing in this statement?
The sum of momenta of the two objects before collision is equal to the sum of momenta after the collision

1. no external force is acting on it    
2. no internal force is acting on it    
3. external force is acting on it    
4. internal force is acting on it    

Mathematically state law of conservation of momentum.

Mathematically represent, “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.”

“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:

1. Law of conservation of momentum    
2. Law of conservation of acceleration    
3. Law of conservation of velocity    
4. Law of conservation of mass    

A book is kept on a table. Gravity acts on the book and pushes it down. But the book does not go down. Why?

1. An equal and opposite force is exerted by the table.
2. An unequal and opposite force is exerted by the table.
3. An equal force is exerted by the table.
4. An opposite force is exerted by the table.

A book is kept on a table. Newton’s third law applies here.

1. True
2. False
