Ch.11 Motion, Distance, Displacement, Speed, Velocity

How are distance and displacement different?

• Distance- how far out of place a object is. Displacement- how much ground a object has covered

• Distance- how much something weighs to how much ground it covers. Displacement- how far out of place a object is.

• Distance- how far you can throw something Displacement- how far it takes you to get to the original starting point in which you began.

• Distance- How much ground an object has covered. Displacement- how far out of place an object is.

if an object in motion is going in two different directions, to figure out the displacement you would

• add

• subtract

• divide

• multiply

if an object in motion is going the same direction, then you would do what to figure out the displacement

• add

• subtract

• divide

• multiply

is the movement in relation to frame reference. Ex: train passes by people on platform, the people on platform see the people speeding by (in motion), but the people on the train, looking at one another don't seem to be moving at all.

• motion

• speed

• objective motion

• frame of reference

is then length of the path between two points

• displacement

• distance

• velocity

• motion

direction from where the starting point and the length of a straight line from the starting point to the ending point.

• distance

• displacement

• motion

• velocity

a quantity that has magnitude and direction

• speed-slope

• acceleration

• relative motion

• vector

what two ways can we describe speed

• average speed and instantaneous speed

• acceleration and displacement

• distance and displacement

• motion and velocity

measure of the total duration of the trip

• speed

• motion

• average speed

• instantaneous speed

what does a car's speedometer measure?

• instantaneous speed

• graphing motion

• slope-speed

• duration speed
