AQA PHYSICS
✔✔bearing - ✔✔A three digit angle measured from north in a clockwise direction.
✔✔distance - ✔✔The length of a path between two points
✔✔Speed - ✔✔distance/time
✔✔Velocity - ✔✔Speed in a given direction
✔✔Acceleration - ✔✔The rate at which velocity changes
✔✔Acceleration equation - ✔✔final velocity-initial velocity/time
✔✔uniform acceleration - ✔✔constant acceleration
✔✔uniform acceleration equation - ✔✔final velocity^2-initial velocity^2 = 2 x
acceleration x distance
✔✔distance-time graph - ✔✔gradient = speed
✔✔velocity-time graph - ✔✔shows how velocity is related to time
✔✔Friction - ✔✔A force that opposes motion between two surfaces that are in contact
✔✔drag - ✔✔resistance by friction from air or water moving over a surface
✔✔terminal velocity - ✔✔the constant velocity of a falling object when the force of air
resistance is equal in magnitude and opposite in direction to the force of gravity
✔✔factors affecting terminal velocity - ✔✔shape and area
✔✔A zero resultant force means - ✔✔no acceleration
✔✔newton's second law - ✔✔F = ma
✔✔Inertia - ✔✔The tendency of an object to resist a change in motion
✔✔Newton's First Law - ✔✔An object at rest stays at rest and an object in motion stays
in motion with the same speed and in the same direction unless acted upon by an
unbalanced force.
