Carousel - Newton's laws, thinking distance

State Newton's third law.

When two objects interact, the forces exerted on one another are equal in size and opposite in direction

Define thinking distance of a vehicle

The distance a vehicle moves without changing speed during the driver's reaction time

State Newton's first law.

When the resultant force acting on an object is zero, there is no change to the object’s motion

Define conservation of momentum

Total momentum before the event = total momentum after the event

Give four factors that can affect a person's reaction time

Tiredness, drugs, alcohol and tiredness

Define breaking distance of a vehicle

The distance of a vehicle moves whilst the breaks are slowing the vehicle to stationary

State Newton's second law

When a resultant force acts on an object, the object accelerates

Give four factors that can affect the braking distance of a vehicle

Speed, weather conditions, road conditions, conditions of tyres/breaks

Give the factor that increases both thinking distance and braking distance

The speed of the vehicle

Define stopping distance of a vehicle

The sum of the thinking distance and braking distance
