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

☆Inertia, property of a body by virtue of which it opposes any agency that attempts to put it in motion.

☆R: F = G(m1m2)/R2. is the formula.

☆Δ p = F net Δ t . F net Δ t F net Δ t is known as impulse and this equation is known as the impulse-momentum theorem.

Answer 2

Answer:

Ans 1 . A property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force is called inertia.

Ans 2. R: F = G(m1m2)/R2.

Ans 3. Impulse is the integral of a force, F, over the time interval, t, for which it acts. Since force is a vector quantity, impulse is also a vector quantity. Impulse applied to an object produces an equivalent vector change in its linear momentum, also in the resultant direction.
