Study Notes
Stopping Distances
- Stopping distance considers thinking distance and breaking distance
- Thinking distance is the distance a driver travels whilst reacting to a hazard
- Breaking distance is the distance taken to stop after a driver applies the brakes
- Thinking distance depends on reaction time and speed
- Breaking distance depends on the speed of the vehicle and friction between the tires and the road
Momentum
- Momentum is a measure of how easy it is to stop something that is already moving
- Momentum is always conserved
- Momentum is a vector quantity (has magnitude and direction)
- Momentum = mass x velocity (p = mv)
Newton's First Law of Motion
- If forces are balanced, an object is either at rest or moving at a constant speed in a straight line
- If forces are unbalanced, the object will accelerate in the direction of the resultant force
Newton's Second Law of Motion
- The resultant force on an object is proportional to the rate of change of momentum
- Force = mass x acceleration (F = ma)
- Mass is a measure of the amount of matter in an object
- Weight = mass x gravitational field strength (W = mg)
Newton's Third Law of Motion
- Action and reaction forces are equal and opposite
- Every action has an equal and opposite reaction
- Forces always act on different objects
