FORCES AND FREE BODY DIAGRAMS

FORCES AND FREE BODY DIAGRAMS. What is a Force?. A force is a push or a pull . All forces have two properties: Direction and Size (magnitude) Units - Newton (N) It is equal to a A force acts ON one object FROM another object (an object cannot exert a force on itself!!).

Group Work

Group Work. A 10-kg box slides on a level floor. Make a force diagram for it. What is its weight ? Its coefficient of kinetic (sliding) friction against the floor is m k = 0.5 . What is the force of friction between box and floor? What is the acceleration of the box?

Chapter 8

Chapter 8. What, if anything, is wrong with the force diagram for a bicycle that is accelerating toward the right?. 1. It does not draw each object separately. 2. It draws interactions between one body and itself. 3. It fails to identify all relevant forces. 4. Nothing is wrong.

Activity 81 Major Concepts

Activity 81 Major Concepts. If more than one force acts on an object , the forces will reinforce or cancel one another, depending on their direction and magnitude. Unbalanced forces result in a nonzero net force that will cause the object to accelerate (a change in speed or direction).

Forces and Motion Review

Forces and Motion Review. 8 th Grade TAG Physical Science. Force. A push or pull Unit of force = kg*m/s 2 = N (newton). How do forces affect the motion of an object?. When forces are balanced, net force = 0, so no change in an objects motion
