3 Types of Motion
- Uniform Motion
- Accelerated Motion
- Non-Uniform Motion
3 Types of Motion Graphs
- Displacement (distance, position) - Time Graph
- Velocity (speed) - Time Graph
- Acceleration - Time Graph
Equations that describe Uniform Motion
v is constant
∆d = v · ∆t (vector)
d = v · ∆t (scalar)
Equations that describe Accelerated Motion + 5 variables
- Newton Eq
- Speed Eq
- EOD (V1)
- EOD (V2)
- Galileo Eq
5 Variables: a, d, V1, V2, ∆t
Equations that describe Non-Uniform Motion
v ≠ constant
a ≠ constant
Average Velocity = displacement / time ( Vav = ∆d / ∆t )
Average Speed = distance / time ( v / ∆t )
What is the meaning of area on a time-acceleration graph?
Area on a t-a graph represents a change in velocity
What is the slope of a displacement-time graph
the slope of a time-displacement graph is the (instantaneous) velocity
What is the slope of a Velocity/Speed-time graph?
The slope of a Velocity/Speed-Time graph represents the Acceleration
