- P5 (Forces and Motion)
- walk-1.5m/s run-3m/s cycling-6m/s
- car-25m/s train-55m/s plane-250m/s
- speed = distance*time
- Accelleration
- change in velocity/time
- final veloc.-initial veloc. = 2(accel.*dist.)
- Distance-time graphs
- gradient = speed
- straight = steady speed
- flat = stationary
- curve = accelerating/decelerating
- velocity-time graphs
- gradient= acceleration
- flat=steady speed
- steep= greater accel.
- downhill-decel.
- curve-changing accel.
- uphill-accel.
- terminal velocity
- forces are equal
- Newtons first law
- resting obj. rest, moving obj. stay moving
- 2nd law
- F=ma
- 3rd
- 2 obj. react - equal and opposite forces
- walk-1.5m/s run-3m/s cycling-6m/s
