* Universal Law of Gravitation
* Second Law of motion
* Third Law of motion
Answers
☣Universal Law Of gravitation
➡Universal law of gravitation states that every object in this universe attracts every other object with the force which is directly proportional to their masses and inversely proportional to square of distance between them.
☣Second law of motion
➡According to Newton second law of motion the rate of change of velocity is directly proportional to applied unbalanced force.
Or we can say that the acceleration of a body is directly dependent on its mass and the net force acting on it.
☣Third law of motion
➡According to newton third law for every action there is equal and opposite reaction in direction of force.
↪Ex- Recoil of gun , When a person jumps of the boat to sea edge. etc.
Answer:
According to the universal law of gravitation , the gravitational force of attraction between two masses separated by a certain distance is directly proportional to the product of their masses and inversely proportional to the square of the distance between the masses.
If m1 and m2 are the masses separated by a distance r then,

Here G is called the Universal gravitational constant. Its value is 6.67 × 10-11 Nm2kg-2
The rate of change of momentum is directly proportional to the applied force and takes place in the direction of the applied force.
eg: A cricket player while catching a ball, lowers his hands in the direction of the ball.
The third law of motion states that the action = reaction at the point of contact. This means that if you apply a force on an object, the object will apply an equal and opposite force on y ou at the point where the contact is being made.
