Speed Distance travelled per unit time Velocity A vector quantity that tells how much an object's position changes during a time interval Average Velocity The ratio of the change of position to the time interval during which the change occurred Upgrade to remove ads Only $1/month Constant Velocity Constant speed and constant direction Instantaneous Velocity The speed and direction of an object at a particular instant in time. Acceleration The change in velocity divided by time. Energy The property of an object that allows it to produce change in the environment or in itself. Component Vector The form of a vector that combines the horizontal and vertical components of the vector. Resultant Vector The sum of two or more vectors. Projectile An object with independent vertical and horizontal motions that moves through the air only under the force of gravity after an initial thrust. Free Fall the motion of a falling object when the only force acting on it is gravity.
