Ap Physics 1 Siegel Unit 1: 1-D Kinematics

Front 1

Kinematics

Back 1

Branch of physics that describes the motion of objects without consideration for the force that causes the motion.

Front 2

Distance

Back 2

-amount of ground covered or the path length of a particle.
-always positive
-always greater than or equal to displacement
-unit: meter

Front 3

Displacement

Back 3

Front 4

Average Speed

Back 4

-distance divided by time
-units: m/s
-always positive

Front 5

Average Velocity

Back 5

Front 6

Back 6

slope = velocity and average velocity
flat line = not moving
straight line = constant velocity
acceleration =0
y-intercept = initial position

Front 7

Back 7

slope of tangent = instantaneous velocity.
leveling off = slowing
getting steeper = speeding up
can determine acceleration by comparing sign of velocity with speed change

Front 8

Acceleration

Back 8

Front 9

Speeding up/slowing down

Back 9

Objects speed up when acceleration and velocity have the same sign. They slow when their signs oppose each other.

Front 10

Back 10

slope=acceleration
value = velocity
y-intercept = initial velocity
flat = constant velocity
slowing = line trending to zero
speeding up = line trending away from zero

Front 11

Back 11

In this class, we mostly study constant acceleration (flat line).

T/F You can tell the velocity or speed from this graph.

Hint 11

False
