What is newtons first law?
An object will remain stationary or moving unless a force acts against it
What is newtons second law?
Force(N) = mass(kg) x acceleration (m/s^2)
What is newtons third law?
For every action there is an equal and opposite reaction
What is terminal velocity?
Terminal velocity is the maximum, constant speed reached by a falling object when the upward force of air resistance (drag) equals its downward weight in other words, when air resistance equals to the weight, the terminal velocity is reached.
How does air resistance relate to velocity?
They are directly proportional:
If air resistance increases, so does velocity.
If air resistance decreases, so does velocity.
What is stopping distance?
The thinking distance combined with the breaking distance to create the total distance it takes for a vehicle to stop
What is the thinking distance?
The distance travelled in between the driver realising he needs to break and actually breaking
What is the breaking distance?
The distance taken to stop once the breaks are applied
What are some factors affecting thinking distance?
-how fast the car is going
-level of intoxication
-tiredness of the person
-poor visibility
What are some factors affecting breaking distance
-the speed of the vehicle
-the mass of the vehicle
-the condition of the tires( tread) and breaks
- the condition of the road (weather)
