Answer:-

In physics a law describes a natural phenomenon, but does not attempt to describe how it works.

Newton's law of gravitation describes the attractive force F between two bodies with masses m1 and m2, which are a distance r apart.

f = gm_1m_2/r²

Where G is the gravitational constant.

This is a law because it describes the force but makes not attempt to explain how the force works.

A theory is an explanation of a natural phenomenon. Einstein's General Theory of Relativity explains how gravity works by describing gravity as the effect of curvature of four dimensional spacetime.

Einstein also produced an equation which describes gravity. It may look simple, but in reality it is very complex and very hard to solve.

Gμν=\frac{8\pi \: g}{ {c}^{2} } tμν

So, we have both a law and a theory of gravity.

Alenkasestr [34]

Answer:

Explanation:

Velocity is defined as the rate of change of displacement.

velocity is a vector quantity, that means it requires both magnitude and direction to completely explain the velocity.

For example, the velocity is 5 ms due east, it means an object is moving with speed 5 ms in the direction of east. We can say that the object covers the displacement of 5 m in one second due east.
