## Components of vectors

See on Scoop.it – PHYSICAL SCIENCES BREAK 1.0 Any vector can be resolved into a horizontal and a vertical component. If R  is a vector, then the horizontal component of R is R x and the vertical component is R y. Chipa Thomas Maimela‘s insight: A number of vectors acting together can be… Continue Reading “Components of vectors”

## Conservation of momentum

See on Scoop.it – PHYSICAL SCIENCES BREAK 1.0 When they come into contact, ball 1 exerts a contact force on the ball 2, F B1, and the ball 2 exerts a force on ball 1, F B2. We also know that the force will result in a change… Continue Reading “Conservation of momentum”

## Change in momentum

## 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:… Continue Reading “Change in momentum”
