Explain 3 laws of Newton?
Answers
1. first law :
an object continues to be under the state of uniform motion unless an external force acts on it.
suppose a block is kept on floor. it will remain at rest until we apply some external force to it.
2. second law:
force is a product of mass and acceleration.
f = m×a
it gives the magnitude of force.
3. third law:
for every action, there is an equal and opposite reaction.
for instance, when you sit on a chair, your body exerts a force downward and that chair needs to exert an equal force upward or else the chair will collapse.
Answer:
newton law
Newton 1st law
an object continues to remain at rest or in a state of uniform motion along a straight line unless an external unbalanced force acts on it.
newton first law explains the phenomenon of inertia.
Newton 2nd law
the rate of change of. momentum is proportional to the applied force and the chance of momentum occurs in the direction of the force.
Newton 3rd law
every action force has an equal and opposite reaction force which acts simultaneously.
