What is the second law of motion?

Newton’s second law of motion is as follows: The acceleration of an object as obtained by a net force is directly proportional to the size of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

Newton’s third law of motion states that: For every action, there is an equal and opposite reaction. This means that in every interaction, there is a pair of forces acting on the two participating objects.

Check Point

A. State True or False

1. Newton’s third law states that every object will remain at rest or in uniform motion unless acted upon by an external force to change its motion.

2. The acceleration of an object as obtained by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force.

3. Newton’s third law states that every action is just an action with no expected reaction.

4. The law of conservation of mass is same as Newton’s law.

5. An object in motion will continue to be in motion unless acted upon by an external force to change its state.

 

B. Fill in the blanks

1. Newton’s first law states that every object will remain at ……… or in uniform motion in a …………… line unless compelled to change its state by the action of an ………………….. 

2. Newton’s third law is for every ……….., there is an equal and opposite………..
