I am having a problem with my physics homework. I don't understand displacement please help!!!!?

Question

I have looked all over my book for the formula and was unable to find it and as far as I know we didn't cover it in class. The homework is due tonight so will someone please help me?

Answer 1

Displacement is how far you are from where you started and in what direction.



Do not confuse Displacement and Distance



Example: Your school has a circular running track. 1 lap is 200 meters.



If you run 5 laps, what is your displacement? 0 meters because when you finish you are where you started



If you run 5 laps, what distance did you run?

5 * 200 = 1000 meters



Another example:



You walk 100 m north and your friend walks 100 m south.

Do you have the same displacement? No. In this case the distance from where you started is the same BUT the directions are different



You both walked the same distance though

Answer 2

the significant difficulty right this is that the upward bouyant rigidity exerted via the water on the boat is comparable to the burden of the water displaced via the boat. So if the boat has an area "A" and sinks to a intensity H then the quantity of water displaced via the boat is AH. The bouyant rigidity of the water is then the mass of the displaced water (density of water x AH) circumstances "g" Bouyant rigidity = (density)AHg If the boat is floating below those situations then you definately've equilibrium and the burden of boat + occupants in basic terms equals the bouyant rigidity. M(entire)g = (density)AHg So now think of the left facet decreased while Tom jumps out. The boat does no longer sink as a procedures and the bouyant rigidity would be distinctive even even though it is going to back equivalent the hot entire weight . Writing a 2nd equation for this new subject, you are able to then be waiting to calculate the version between the previous and new depths the boat drafts.

Answer 3

Before you ask for a formula try to understand what displacement means.

Answer 4

Likely you are referring to displacement of an object related to velocity and acceleration

d=d0+v0*t+.5*a*t^2

for linear acceleration, d0 is the displacement at t=0, v0 is the instantaneous velocity at t=0

Answer 5

D = VT

D = AT^2/2
