- forces and motion
- resultant forces
- HOW?
- subtract the 2 oppasite forces
- WHAT DO THEY MEAN?
- if the forces are balaned...
- ...and the resultant force is 0
- it is moving at a constant velocity OR....
- not moving at all (stationary)
- it is moving at a constant velocity OR....
- ...and the resultant force is 0
- if the forces are unbalanced...
- Decelarating
- Accelarating
- Changing direction
- if the forces are balaned...
- HOW?
- velocity and speed
- SPEED
- only has size
- SCALAR QUANTITY
- only has size
- VELOCITY
- has size and direction
- VECTOR QUANTITY
- has size and direction
- SPEED
- resultant forces
