chapter 1 study guide Flashcards
be able to interpret data on a distance-time graph, data regarding velocity of a car on said graph, data regarding reference points on a graph, data regarding speed, velocity, and acceleration on a graph
look it up thug
what is the equation for calculating average speed
v=d/t, average speed=total distance/total time
be able to complete word problems by calculating average speed
no thanks tbh
what are two things you must know to describe velocity?
speed and direction
on a speed-time graph, what does a perfectly horizontal line indicate?
constant speed
what is the term for speed at any given time?
instantaneous speed
when you graph the motion of an object, on which axis do you put the distance?
vertical
when you graph the motion of an object, on which axis do you put the time?
horizontal
describe how constant velocity is shown in a speed-time graph
straight horizontal line
when an object is at rest, what is its speed?
0 m/s
which vocabulary term describes how velocity changes with time?
acceleration
a soccer ball takes 20 s to roll 10 m. what is the average speed of the soccer ball?
0.5 m/s
a car travels 200 m in 2 hours. calculate the average speed of the car
100 km/hr
