Momentum

Question 1

Newtons first law

Answer 1

An object will remain at rest or continue to travel with constant velocity unless acted on by a resultant force

Question 2

newtons second law

Answer 2

the net force acting on an object is directly proportional to the change of momentum and is acting in the same direction

Question 3

Newtons third law

Answer 3

when two objects interact they exert opposite but equal forces on one another

Question 4

What is the area under a force time graph

Answer 4

it is the impulse over that time duration which is equal to the change of momentum

Question 5

What is the principle of the conservation of momentum

Answer 5

for a system of interacting objects, the total momentum in a specified direction remains constant, as long as no external forces act on the system.

Question 6

What is conserved in a perfectly elastic collision

Answer 6

total kinetic energy is conserved
momentum is conserved

Question 7

what is lost in an inelastic collision

Answer 7

total kinetic energy is not conserved
