- DT Graphs
- Speed=Gradient= Vertical/Horizontal to work out speed.
- Speed is how fast your going
- Velocity is speed in a certain direction
- FORCE
- If no resultant on a MOVING object they will continue at SAME SPEED
- If non-zero resultant force then object will ACCELERATEin direction of force
- Overall force will ALWAYS accelerate
- Steady speed=ZERO resultant force
- When two objects interact, forces is equal and opposite.
- FRICTION
- Resistance caused by air resistance or drag
- As SPEED increases, DRAG increases
- Elastic POTENTIAL energy.
- DT Graphs
- Resultant force on stationary object=ZERO the object WONT move.
- If no resultant on a MOVING object they will continue at SAME SPEED
