Answer #1

17) zero ( In deep space force of gravity is zero, that is why weight will be zero)

18) F_horizontal - F_friction = ma

1 N - F_friction = 1kg x 0.7 m/s2

F_friction =0.3 N ANSWER

19) MASS (mass is the measure of inertia)

20) acceleration (direction of net force gives direction direction of acceleration of a body)

Please let me know if it was helpful. thanks
