Newton's first law of motion describes the following:

Give two points of difference between mass and weight.

Three forces given by vectors $2 \hat{i} + 2 \hat{j}$,$2 \hat{i} - 2 \hat{j}$,and $-4 \hat{i}$ are acting together on a point object at rest. The object moves along the direction:

An astronaut accidentally gets separated from his small spaceship accelerating in interstellar space at a constant rate of $100 \; m/s^2$. What is the acceleration of the astronaut the instant after he is outside the spaceship (in $; m/s^2$)? (Assume that there are no nearby stars to exert gravitational force on him.)

What is inertia?

Write and explain Newton's first law of motion.
