Khan Academy Free Body Diagram

Youll hear the terms balanced forces and unbalanced forces a lot when youre dealing with physics and what i wanna do in this video is give you a bunch of scenarios and have you think about whether the forces in these scenarios are balanced or unbalanced. And its sitting on this you could view this is an inclined plane or a ramp or some type of wedge.

Practice choosing the correct free body diagram for an object.

Khan academy free body diagram. So that was pretty straightforward the free body diagram for just the block. Lets say i have some type of a block here. So lets start with the scenario where we.

So the mass of this block is equal to m. Here is an example of a free body diagram for a block of cheese resting on a table see figure 2 below. And its really important to see that because notice in the free body diagram all you see is the block.

Sal draws a free body diagram for a box held stationary against a wall with a force at an angle theta. If youre seeing this message it means were having trouble loading external resources on our website. And lets say this block has a mass of m.

And to be clear this five newtons this is equal to the weight the magnitude of the weight of the object. If youre seeing this message it means were having trouble loading external resources on our website. Sal draws a free body diagram for a box held stationary against a wall with a force at an angle theta.

So in this situation you have ten newtons downward and you would have ten newtons upward. Gravity pulls down on the cheeses mass with weight w w w and the table pushes up on the cheese with a normal force n n n. Another way that you might see it is like this where you see the body.

This is another way that you might see free body diagrams drawn. But now lets draw the free body diagram for the shelf. And from the outside of the body you see the vectors being drawn.
