Explain three laws of motion explaining those using 4 methods
Answers
Answer:
Newton’s laws of physics:
1.EVERY BODY CONTINUES TO BE IN REST OR OF UNIFORM MOTION UNLESS AN EXTERNAL FORCE ACTS ON IT.
Example:
i) A book on your table does not come towards you unless you put effort to take it
ii) The Earth and other planets will not revolve around the sun when there exists no gravitational field.
iii) A rocket or any other propelling object does not take off unless a force equal to its weight is applied on it.
2.THE FORCE ACTING ON A BODY IS DIRECTLY PROPORTIONAL TO THE RATE OF CHANGE OF MOMENTUM
Example:
i) When you disturb an object in a short period of time, it has more effect i.e impulse.
ii) Since F=ma, a car of small mass moving with great acceleration, hitting on a wall and truck having great mass moving with small value of acceleration, hitting on the same wall will have similar effects (Hope you can understand what im trying to convey)
3. EVERY ACTION HAS AN EQUAL AND OPPOSITE REACTION
Example:
i) If you hit a wall, your fist will get hurt.
ii) If you push an object, it will start moving.
iii) If two vehicles crash each other, kinetic energy is converted into light, sound and heat energy.
iv) In simple words, the third newtonian law is same as that of “KARMA”
