(refer to examples in Summary Sheets Part 1)<\/p>\n

Force is a vector<\/span><\/strong><\/p>\n

Force is a vector quantity.\u00a0 The direction that a force acts in will dictate the effect that it has.<\/p>\n

Balanced Forces<\/span><\/strong><\/p>\n

Two forces acting in opposite directions are said to be balanced<\/strong>.\u00a0 The effect is equivalent to no force<\/strong> acting on the object at all.<\/p>\n

Newton\u2019s First Law<\/span><\/strong><\/p>\n

\u201cAn object will remain at rest or move at a constant velocity in a straight line unless acted on by an unbalanced force\u201d.<\/p>\n

This means that if the forces acting on an object are balanced, then the object will remain stationary if it was already stationary.\u00a0 For a moving object, if the forces acting on it are balanced, then it will continue to move in a straight line at a constant velocity.<\/p>\n

balanced forces \u2194 Object at rest OR object moving at a constant velocity in a straight line<\/p>\n

\u00a0<\/span><\/strong><\/p>\n

Newton\u2019s Second Law<\/span><\/strong><\/p>\n

If an overall resultant (or unbalanced) force is applied to an object, then the object will accelerate in the direction of the unbalanced force.<\/p>\n
