What is the law of inertia?
a. an object in motion will stop after a certain distance.
b. an object in motion will stay in motion, and an object at rest will stay at rest, unless
acted upon by an outside force.
c. for every action, there is an equal and opposite reaction.
d. the weight of an object is equal to its mass times its acceleration.

Law of inertia..it’s the tendency of object to remain at rest or motion .
A)it’s because of friction
B)it’s newton first law of motion
C) it’s Newton third law of motion
D) the weight of an object is defined as the force of gravity on the object and be calculated as the mass time the acceleration of gravity,
W=mg..since the weight is force .and it’s Si unit is the Newton.!!
Hope this help you..!
