What is net force? Sum of all forces acting on an object.
What is average speed? Total distance divided by total time.
What is sliding friction? Force that acts in the opposite direction to the motion of a surface sliding on another surface
What is speed? Distance divided by time.
What is a force? A push or pull exerted on a body or object.
What is displacement? Distance and direction of an object from its starting point.
What is friction? Force that opposes the sliding motion of 2 surfaces in contact.
What is air resistance? Force that opposes the motion of objects that move through the air.
What is velocity? Vector speed and direction of motion.
What is instantaneous speed? Speed of an object at a specific point in time.
What is acceleration? The change in velocity divided by the time for the change to occur.
What is the difference between distance and displacement? Displacement involves distance and direction.
What is the difference between speed and velocity? Speed is distance over time and velocity is speed and direction.
