The gravitational force is an attractive force that a mass exerts on another mass when the former is placed in the latter’s gravitational fi...

As we have seen in this post during a collision between two object the velocity of the two colliding objects changes. Hence you would agr...

As we have seen in this previous post , in a close system the sum of linear momentum is a constant. Hence in any collision if the sum of li...

The linear momentum is the product of the mass of an object and the velocity of an object. Now if you have two objects that are moving to...

Every object has a quantity known as the mass. The mass is simply the quantity of matter that it contains. When according to the law of gr...

Linear momentum is a physical quantity that depends on the mass and the velocity of the object. Fig 1 below shows an object that has mas...

It is simply the energy that a body possesses due to its position above the surface of the earth. There is a second form of potential energy...

Kinetic energy is one if the eight forms of energy. It is simply the energy that a body possesses due to its motion. The kinetic energy of a...
