4. Explain Newton's second law of motion: Law of Acceleration.
5. Solve word problems related to the Law of Acceleration
​

Answer 1

Answer:

3.

(i) Dusting bed with a broom removes dust due to inertia of rest

(ii) When you shake a branch the leaves get detached

(iii) Athlete taking a short run before a jump

4. *first part*

Newton's second law of motion -- force on any body is directly proportional to the product of mass and acceleration produce on that object due to force. i.e -- F = ma

where, f is directly proportional to a and m.

*second part*

The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
