Question

what is retardation .Explain all laws of motion​

Answer 1

Answer:

Retardation means negative acceleration. ... So when the velocity of a body increase, the acceleration is said to be positive and when the velocity of a body decrease, the acceleration is said to be negative(Retardation). A body is said to be retarded if its velocity is decreasing.three laws of mechanics describing the motion of a body.

1. The first law states that a body remains at rest or in uniform motion in a straight line unless acted upon by a force.
2. The second law states that a body's rate of change of momentum is proportional to the force causing it.
3. The third law states that when a force acts on a body due to another body, then an equal and opposite force acts.

Answer 2

Retardation is the act or result of delaying; the extent to which anything is retarded or delayed; that which retards or delays.

• The first law states that an object either remains at rest or continues to move at a constant velocity, unless it is acted upon by an external force.
• The second law states that the rate of change of momentum of an object is directly proportional to the force applied, or, for an object with constant mass, that the net force on an object is equal to the mass of that object multiplied by the acceleration.
• The third law states that when one object exerts a force on a second object, that second object exerts a force that is equal in magnitude and opposite in direction on the first object.
