What Is A Forcehttp://www.novel-learning.com/
An interesting video meant for primary / elementary school students.
A force is a push or a pull. We can’t see a force, but we can see the effects of a force. A force can move a stationary object, stop a moving object , or change its direction. A force can change the speed of an object. It can also change the shape of an object
The interaction of forces makes the world we live in the way it is.http://youtu.be/uoKo3DbfYZk
