$A$ jet engine works on the principle of Newton's:

$A$ body of mass $500 \, g$ is at rest on a frictionless surface. Calculate the distance travelled by it in $10 \, s$ when acted upon by a force of $10^{-2} \, N$. (in $, m$)

State Newton's third law of motion. Give two examples.

When a net force acts on an object,the object will be accelerated in the direction of the force with an acceleration proportional to:

What type of force is acting in the cases given above?

What is momentum? Write its $SI$ unit. Interpret force in terms of momentum. Represent the following graphically:
$(a)$ Momentum versus velocity when mass is fixed.
$(b)$ Momentum versus mass when velocity is constant.
