Describe the motion

Displacement vs time plot

Slope: = d/t = vel.

velocity is constant +

3. a = 0 (vel. not changing)

Ex) d (cm)

Displacement vs time plot

1. y changes: ?    2. Slope: ?

↓

1. Y changes: d constant

2. Slope: d/t = v

v = 0

Ex)

Displacement vs time plot

1. y changes: ?    2. Slope: ?

↓

1. Y changes: d inc.    2. Slope: d/t = v

V is increasing

3. Constant accel. (smooth increase of v)

Ex)

Displacement vs time plot

1. y changes: ?    2. Slope: ?

↓

1. Y changes: d inc.    2. Slope: d/t = v

V is increasing

3. Not Constant acceleration

Ex)

Velocity vs time plot

1. y changes: ?    2. Slope: ?

↓

1. y changes: increasing v

2. Slope: v/t = a

acceleration is constant +

Ex)

Velocity vs time plot

1. y changes: ?    2. Slope: ?

↓

1. y changes: decreasing v

2. Slope: v/t = a

acceleration is constant and neg.
