What is braking distance?
The distance a vehicle travels under the braking force .
Name an equation that links braking distance , stopping distance and thinking distance?
Stopping distance= thinking distance + braking distance
What is inertia?
The tendency of an object to remain in its same state of uniform motion or rest.
what is newton's first law?
If a stationary object’s resultant force is zero, the object will remain stationary. If a moving object’s resultant force is zero, the object will continue to move at the same speed, and in the same direction
What is a contact force?
A force that occurs when objects are physically touching .
What is stopping distance?
The sum of the thinking and braking distances.
What is thinking distance?
The distance a vehicle travels during the driver’s reaction time.
what is a resultant force?
The single force that can replace all the individual forces acting on an object, and have the same effect.
What is newton's third law?
The forces that two objects exert on each other when they interact are equal and opposite
What is newton's second law?
An object’s acceleration is directly proportional to the force applied to it, and inversely proportional to its mass
What is the difference between scalar and vector?
A Vector has magnitude and direction .
A Scalar has just magnitude .
What is the equation that contains Weight ,mass and gravitational field strength?
weight = mass × gravitational field strength
