GOAL!

Building and Programming the Catapult

Programming

Friction

Example

A force between two surfaces that are sliding and they must in contact with each other

Also

Friction always works in the opposite direction from the direction of moving object. Friction can slow a moving object

Down.

Next time

we will have

Inertia

Example

Is

Resistance of objects to change their status

Welcome

Newton's First Law

An object at rest tends to stay at rest and an object in motion tends to stay in motion unless acted upon by an unbalanced force

watch this
