Rube Goldberg & the Physics of Motion Flashcards

1

Whose laws describe the physics of motion?

Beth Marschner
Sir Crush of "Finding Nemo"
Sir Isaac Newton
John Dalton

2

An object can be accelerating even if its speed is constant.

False
True

3

Distance vs. Time Graph

stopped
decreasing speed
going back to start
constant

4

Which car has the fastest speed?

Mr. Carlin's car currently pareked in the parking lot.
Car B
Car C
Car A

5

Speed in a specific direction is called...

Force
Velocity
Mass
Acceleration

6

Units for speed

meters per second (m/s)
seconds per meter (s/m)
seconds (s)
meters (m)

7

The units for acceleration

m/s
meters
seconds
m/s2

8

If a car travelled 280m in 40s, what was its average speed?

7 m/s
8 m/s
5 m/s
6 m/s

9

The total distance an object travels divided by the total time it travels is known as:

terminal velocity
constant speed
instantaneous speed
average speed

10

To find average speed you:

divide total time by total distance
none of the above
multiply distance by time
divide total distance by total time

11

In a graph of SPEED vs. TIME what does B represent?

constant deceleration
constant speed
constant acceleration
object at rest

12

Which value is a velocity?

47 km/hr
20 m/s
20 m/s North
16 mi/hr

13

Distance vs Time Graphs: choose ALL that are true!

when it goes back it shows u moving forward
A horizontal line shows an object is not moving
A straight diagonal line shows something moving at a constan
The steeper the line, the faster it is moving

14

Why use simple machines?

They're fun.
They make work harder to do.
They give you a work out.
They make work easier to do.

15
