Phys Sci Ch 11.1 Measuring Motion
a change in position relative to reference point
frame of reference
a way to show precise location of object in space, time is:
measures distance between start and end point
how fast object moves in a given time
what is the formula for average speed?
what is the formula for distance?
what is the formula for time?
what is the speed of an object in a direction called?
velocity of an object when it moves toward reference point
velocity of an object when is moves away from reference point
addition of positive and negative velocities is called:
what speed is the speed when distance and time are equal?
what is the SI unit for speed?
the graph that shows speed of an object
what does the slope of a distance-time graph show?
if the slope on a distance-time graph is steep is the object travelling fast or slow?
what is the slope of an object thats not moving
distance, y axis
what is the independent variable on a distance-time graph and which axis is it on?
time, x axis
what is the dependent variable on a distance-time graph and which axis is it on?
