WHAT ARE SOME PRACTICAL EXAMPLES OF RELATIVE VELOCITY?

When we are sitting in a train and the train is not moving but a person outside is moving, we feel that the train is moving. This is because of relative velocity between us and the person.

APPLICATION AND LIMITATIONS OF HOOKE’S LAW

Robert Hooke, an English scientist, gave the Hooke’s Law of elasticity in 1660. It states that for the relatively small deformations of an object, the size of the deformation or displacement is directly proportional to the deforming load or force. With these conditions, the object would return to its original size and shape with removal of the load

VECTOR QUANTITY

Vector quantities are the ones that talk about the magnitude as well as the direction. Magnitude talks about the strength or length.
