Question

Very short type
Q 1. Define inertia.
Q 2. Write the formula for Newton's law of gravitation?
Q 3. What is impulse?
​

Answer 1

Answer:

Q. 1 The tendency of an object to remain in its existing state is called its inertia.

Q. 2 F = G m1m2/r²

Q. 3 Impulse is the change of momentum of an object when the object is acted upon by a force for an interval of time.

Explanation:

Q. 2

F = force

G = gravitational constant

m1 = mass of object 1

m2 = mass of object 2

r= distance between centers of the masses.
