Galileo first of all said that object move with a constant speed when no forces act on them. Newton studied the ideas of Galileo and gave the three laws of motion. These laws are known as Newton’s Laws of Motion.
Newton's First Law of Motion - Any object remains in the state of rest or in uniform motion along a straight line, until it is compelled to change the state by applying external force.
meaning - If any object is in the state of rest, then it will remain in rest until a external force is applied to change its state of rest. Similarly , an object will remain in motion until any external force is applied over it to change its state.
Newton's Second Law of Motion - The rate of change of momentum is directly proportional to the force applied in the direction of force.
p(momentum) = m v
where m = mass
v = velocity
Newton's Third Law of Motion - There is an equal and opposite reaction for every action.

Newton's laws of motion are three physical laws that, together, laid the foundation for classical mechanics. They describe the relationship between a body and the forces acting upon it, and its motion in response to those forces.
