How to solve distance |
D=VxT |
|
|
How to solve Time |
T=D/V |
|
|
How to solve velocity |
V=D/T |
|
|
Define a "Force" |
Contact Non-contact Normal Gravity Tension Friction |
|
|
Examples for forces |
Normal - pushing a door Tension- pulling a wagon Friction- Tug of war Gravity- dropping a pencil |
|
|
how do you draw a F.D |
1. add earth and ground 2. add non-contact 3. add contact 4. circle objects for F.D 5. check off forces once added to the F.D |
|
|
How to tell if it is balanced or not |
1. balanced forces are in a constant motion 2. unbalanced forces having changing velocities |
|
|
how to tell if the object is accelerating or not |
velocity vs. Time the line gets steeper, positive slope Position vs. Time Line is curved |
|
|
How to solve a slope |
y axis divided by X axis |
|
|
(Position vs Time) How to tell if it is in constant motion or not |
Line slope=0 (flat line) |
|
|
(Velocity vs time) How to tell if it is in constant motion |
flat line= constant motion slope ≠ 0 |
|
|
How to find acceleration |
A=Fnet/mass |
|
|
As forces increase what happens |
Acceleration increases direct |
|
|
as mass increases what happens |
acceleration decreases Inverse |
|
|
What is falling |
Accelerating to the ground |
|
|
How do you calculate velocity (cycle 3) |
V=GxT |
|
|
How to calculate the force of gravity |
fg=MxG |
|
|
If there is no air what happens to the forces |
The forces don't act on the objects anymore so the 2 objects would fall at the same time |
