What is inertia? What is momentum ?why are they important in 1st law of motion and 2nd law of motion respectively
Answers
Answer:
your anwer is
Explanation:
because the Newton's 1st law said that a body does not come in rest position until an balanced external force is apply on it or not come in motion until any force act on it
Answer:
inertia is the property of keeping a rest body in a state of rest and the motion body keeping the body in motion until an external force is applied
Explanation:
momentum is the product of mass and acceleration.
momentum is doubled , mass is doubled
momentum is directly proportional to mass and velocity
1 law of motion .
it emphises that if a body in motion it will be in motion and a body at rest will be at rest due to inertia
2 law of motion.
force=mass . acceleration
acceleration = mass/force
acceleration is doubled then mass is halved.
if acceleration is halved then mass is doubled.
so acceleration is inverselly prportional to mass
