Mass and weight Flashcards
What is a stopping distance?
The stopping distance is the distance it takes to stop a vehicle.
Stopping distance equation?
Stopping distance = Thinking distance + braking distance
What is thinking distance?
Thinking distance is how far the vehicle travels during the drivers reaction time.
What is reaction time?
Reaction time is the time between the driver seeing the hazard and applying the brakes.
What is braking distance?
Braking distance is the distance taken to stop once the brakes are applied.
What is the mass on earth?
On Earth to 1kg = 10N. So if your mass is 50kg your weight is (50x10)=500N.
What is mass measured in?
Mass is measured in kilograms.
What is mass?
Mass is just the amount of stuff in an object.
What is weight measured in?
Weight is measured in Newtons.
What is weight?
Weight is the force acting on an object due to gravity.
What is a resultant force?
A resultant force is the overall force acting on an object.
How do you calculate force?
Force (N) = mass (kg) x acceleration (m/s2)
What does a resultant force cause?
A resultant force causes an acceleration.
1st step of core practical?
Sit with your arm resting on the edge of the table.
2nd step?
Get someone else to hold a ruler so it hangs between your thumb and forefinger, lined up with zero.
