![]() In part (c), we show all forces in terms of their x- and y. In part (b), we show a free-body diagram for this situation, as described by steps 1 and 2 of the problem-solving strategy. ![]() Physics Phet forces and free body diagram lab.docx. 1 a, a sled is pulled by force P at an angle of 30°. Physics Classroom Situations Free Body Diagrams-Interactive Situation 1 Description: A rightward-moving car is skidding to stop across a level roadway with locked wheels. Then, since I know that there is an acceleration to the right, I need to draw \(F^t\) greater than \(F^k\), since the net force on the block must be to the right as well. Let’s apply the problem-solving strategy in drawing a free-body diagram for a sled. As there is no vertical motion of block, so N m g. ii) Normal reaction by ground ( N) in + y direction. i) Gravitational force by the earth ( m g) in y direction. So in y direction there are 2 forces on block. A free-body diagram for this situation looks like this: 6. An egg is free-falling from a nest in a tree. A free-body diagram for the girl in this situation looks like this: 5. A girl is suspended motionless from a bar which hangs from the ceiling by two ropes. If I know the value of the friction force, I should also try to draw \(F^k\) approximately to scale with the other two forces. As a result the ground gets pushed and the ground exerts normal reaction on the block ( N ). A free-body diagram for this situation looks like this: 4. \) as having the same magnitude, since there is no vertical acceleration for that block.
