Nuclear Force – Definition | properties of Nuclear Force

We already know about gravitational and electrostatic forces now a question arises that does these forces still hold when we talk about nuclear dimensions as gravitational force between two protons is far too less to hold them and electrostatic force between two protons always a force repulsive in nature . So what hold protons together to form a nucleus.

Acceleration formula Explained with Examples

Acceleration Formula Acceleration is the rate of change of velocity with time.It is a measure of the change in the velocity of an object per unit time and mathematically acceleration formula  is given as For describing average acceleration, we first consider the motion of an object along straight line. Suppose at time t1 object is at point P moving with velocity v1 and at time t2 it is at … Continue reading Acceleration formula Explained with Examples »
