Question

state newton's laws of motion. Use the first law to define force and inertia, and the second law to define acceleration.​

Answer 1

Answer:

First law

In an inertial frame of reference, an object either remains at rest or continues to move at a constant velocity, unless acted upon by a force.[2][3]

Second law

In an inertial frame of reference, the vector sum of the forces F on an object is equal to the mass m of that object multiplied by the acceleration a of the object: F = ma. (It is assumed here that the mass m is constant

Answer 2

Answer:

1]

Newton Law of Motion-

a)First law of motion /Law of inertia. - An object remains in rest or uniform motion in straight line until an external force is applied.

b) Second Law of Motion- Rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of force.

c)Third Law of Motion-When an object exerts a force on another object , the second object at same time exerts force of equal magnitude on first object.

2]First Law of Motion talks about resistance in movement and that is what is called inertia. So, First law of Motion is also called law of inertia. First law of motion also clarifies that only a unbalanced force can bring object in motion.

3]Second law of motion can be summed up in famous formula that is Force=Mass*Acceleration and by this we formula we can derive that Force by Mass is acceleration.
