Additional Physics Edexel

Acceleration A message of how quickly the velocity of an object is changing. It can be possitive or negative.
Action One of a pair of forces. The reaction force acts in the opposite direction.
Collision When two or more objects come into contact with each other.
Deceleration Another term for negative acceleration.
Free-Body Diagram A simplified diagram of an object showing all teh forces acting upon it and the size and direction of those forces.
Gradient A measurement of the steepness of a slope of a graph. The steeper the graph the higher the...
Magnitude A measure of how big something is.
Momentum A quantity describing the movement of an object. Calculated by multiplying the mass by the velocity.
Reaction One of a pair of forces. This acts in the opposite direction to the action force.
Reaction Time The time between when you see or hear somethingand when you react.
Resistance A force that acts in the opposite direction of motion i.e. friction.
Resultant Force The total force that results for two or more forces acting on a single object. It is found by adding the forces together, taking in mind the dircetion.
Risk How likely something unfortunate is going to happen.
Speed A measure of the distance an object travels in a given time.
Stopping Distance The distance a car travels between when the driver sees something and when the car stops.
Terminal Velocity A constant, maximum velocity reached by falling objects. This happens when the weight downwards is equal to the air resistance upwards.
Vector A quantity that has size and direction i.e. velocity.
Velocity The speed of an object in a particular direction.
Weight The force pulling an object downwards. It depends on the mass of an object and the strength of gravity.
