Physics Unit 2 - Force, Acceleration
And Terminal Velocity
- Acceleration
- Non-Resultant Force Creates An Acceleration
- F=m*a
- a=f/m
- m= Mass (Kg)
- a=Acceleration
- F=Resultant Force
- F=Resultant Force
- a=Acceleration
- a=f/m
- Non-Resultant Force Creates An Acceleration
- Forces
- When two object interact the
forces are equal and opposite
- E.G: If you push a trolley it
will push back just as hard
- Reaction Forces
- When two objects interact, the forces they
apply on each other are EQUAL and OPPOSITE
- When two objects interact, the forces they
apply on each other are EQUAL and OPPOSITE
- Frictional Force
- Frintion slows things down
- If an object has no force
moving it then it will always
slow down and stop
- Friction acts in the opposite
direction to movement
- If an object has no force
moving it then it will always
slow down and stop
- To travel at a steady speed,
the driving force needs to
balance the frictional forces
- Frintion slows things down
- When two object interact the
forces are equal and opposite
- Drag
- Also know as fluids E.G: Air or Water
- As Drag Increases, Speed Increases
- This is because as a car speeds up it has much
more friction to work against
- Work harder to maintain steady speed
- This is because as a car speeds up it has much
more friction to work against
- Terminal Velocity
- Terminal velocity is the highest
velocity attainable by an object in
free fall
- Objects falling through fluids reach a
terminal velocity
- Factors Effecting Terminal Velocity
- Area
- Size
- Shape
- A parachute with a larger
surface area has a bigger resistance
- Size
- Area
- Factors Effecting Terminal Velocity
- Objects falling through fluids reach a
terminal velocity
- Terminal velocity is the highest
velocity attainable by an object in
free fall
- Also know as fluids E.G: Air or Water
