Change in momentum

See on Scoop.it – PHYSICAL SCIENCES BREAK 1.0 Click here to edit the title Chipa Thomas Maimela‘s insight: A rubber ball of mass 0,8 kg is dropped and strikes the floor with an initial velocity of 6 m·s−1. It bounces back with a final velocity of 4 m·s−1. Calculate the change in the momentum of…

Change in momentum

See on Scoop.it – PHYSICAL SCIENCES BREAK 1.0 Momentum Chipa Thomas Maimela‘s insight: Lets start with a simple picture, a ball of mass, m, moving with initial velocity, v i, to the right towards a wall. It will have momentum pi=mv i to the right as shown in this picture: https://maimelatct.wordpress.com/ See on everythingscience.co.za

Resultant of perpendicular vectors

The resultant of two or more perpendicular vectors is the vector sum of those vectors. The magnitude of the resultant vector is equal to the square root of the sum of the squares of the magnitudes of the individual vectors. Mathematically, if vectors A and B are perpendicular to each other and have magnitudes A…
