Unit 4 Energy and Momentum

Unit 4 Energy and Momentum. This unit is a continuation of the study of mechanics that trainees studied in Units 2 and 3. It involves looking at mechanics from a different point of view (using work end energy) that can simplify some otherwise complicated situations.

7.1 What are forces?

7.1 What are forces?. Forces act on you all the time. If you surf, you can feel many forces pushing and pulling you in different directions. Gravity always pulls you down, towards planet Earth. This force can be balanced by the support of the surfboard acting upwards.

Balanced and Unbalanced Forces

Balanced and Unbalanced Forces. Unbalanced Forces. When two or more forces are acting on an object and they are not equal in size, we say the forces are unbalanced. Unbalanced forces cause a change in the motion of an object. An apple falling from a tree demonstrates an unbalanced force. .
