Motion is _________________ |
Relative & Constant. Relative to the Earth unless otherwise stated. |
|
|
Speed Defined |
Distance covered per amount of travel time |
|
|
Speed = |
D/t |
|
|
Average Speed Defined |
The total distance covered divided by the totaltravel time. |
|
|
Average Speed = |
D(total)/t(total) |
|
|
Velocity |
Instantaneous speed and direction. |
|
|
Constant Speed |
Steady speed; not accelerating or decelerating. |
|
|
Constant Velocity |
Steady speed & direction; not accelerating or decelerating; straight line |
|
|
Acceleration formed by whom & how |
Galileo; motion on inclined planes |
|
|
Acceleration involves: |
Change in speed or change in direction |
|
|
Acceleration = |
(change in V)/ t |
|
|
Acceleration due to Gravity = |
9.8 m/(s^2) |
|
|
Velocity = |
acc * time |
|
|
Distance from Rest = |
(1/2) × acceleration × time × time |
|
|
If a bird is flying at 10m/s and has a tail wind (wind moving in the same direction as the bird) of 5m/s how fast is the bird moving? |
15m/s |
|
|
A bike is traveling at 20m/s for 10 seconds how far did the bike travel? |
200m |
|
|
Free-fall is an increase in what? Speed or acceleration? |
Speed only |
|
|
