Laws of Motion Notes

For every action force there is an equal in magnitude but opposite in direction reaction force. - Force pairs, actions and reactions, come from interactions - Interaction: two surfaces come in contact with one another - For example: There is an interaction occurring right now between the chair and y ...

What are Forces?
... What is the difference between mass and weight? • Mass is the amount of matter in an object. This does not change in an object as it moves away from the earth. • Weight is caused by gravity. Therefore, the greater the distance, the less the force of attraction. The less the distance the greater the ...
