Equations for Constant Acceleration
(Note: The 2 equations listed below only work
for constant acceleration) |
| |
s = d/t |
|
x = 1/2at2 + vot + xo |
| |
a = dv/dt |
|
v = at + vo |
| |
v = dx/dt |

dx = u/(n+1) x (n+1) + C for n!=1 |

Assume planet Earth and
no air resistance for the following:
- Derivative: the slope at a point.
- Integral: the area under the curve
between two values.
- The negative sign on a vector indicates
direction. It does not indicate that an object is slowing down.
- How to determine if an object is
slowing down or speeding up:
- Speeding up: the acceleration vectors
go in the same direction
- Slowing down: the acceleration vectors
go in opposite directions.
- Acceleration due to Gravity: On the surface of a planet, objects all
fall at the same acceleration if air resistance is negligible,
regardless of their mass.
- Drop an object, throw it up, throw it
down and it still accelerates at the same rate, 9.8 m/s/s downward.
- Throw an object upward and it will reach
zero velocity at the top of its path but the acceleration is still 9.8
m/s/s downward.
- Models: Physics is about model building. Models
always have errors due to simplifying assumptions.
