A force is is any interaction when unopposed will change the motion of an object. 1 of 10 What is motion? Motion is a change in position of an object with respect to time. 2 of 10 Examples of force Pushf/pull gravity/friction/magnetism 3 of 10 Balanced forces Are forces that act on the same object, are in opposit directions and are equal in size 4 of 10 Unbalanced forces Forces that are not opposite or equal. They cause a change in velocity (acceleration) 5 of 10 What is friction? A force that opposes motion between two surfaces 6 of 10 Types of friction static/sliding/rolling/fluid 7 of 10 Newtons 1st law An object at rest will remain at rest and an object in motion will keep moving at a constant velocity unless acted upon by unbalanced forces 8 of 10 Newtons 2nd law If more force is applied, an object will be accelerated more 9 of 10 Newtons 3rd law For every action, there is an equal and opposite reaction 10 of 10
