Newtons third law of motion

We have reached the end of the lesson. Answer the following questions to evaluate yourself. All the best !!

Questions 1 and 2 carries one mark each, question 2 carries 3 marks and 3rd question carries 5 marks.

1. According to Newtons 3rd law of motion, in an action and reaction pair of forces, the forces are:

a) opposite in direction

b) perpendicular in direction

c) parallel in direction

d) none of the above

2. When a large truck pushes a small car with a given force, the small car is applying an equal and opposite force on the truck. State true or false.

3. State Newtons three laws of motion.

4. In the following situations,

a) recoil of gun

b) bouncing of a basket ball

Explain how Newtons third law of motion works. Also identify the action and reaction forces and the bodies in which they are acting.
