Question

define second law of motion

Answer 1

According to Newton s Second Law of Motion, also known as the Law of Force and Acceleration, a force upon an object causes it to accelerate according to the formula net force = mass x acceleration. So the acceleration of the object is directly proportional to the force and inversely proportional to the mass.

✨Second Law of motion -

The rate of change of momentum of object is proportional to the applied unbalanced force in the direction of the force.

• A cricket player lower his hand while catching a ball by lowering the hands, he increases the time of catching the ball. As a result, the rate of change of momentum decreases and the force exerted on his hand is less.
• China ware are wrapped is staw paper before packing. The straw paper between the chinaware increases the times. Hence, they strick against each other with a less force and are less damaged.
