scalar - A physical quantity that possesses magnitude only., vector - A physical quantity that possesses a magnitude and a direction., speed - The rate of change in distance., velocity - The rate of change in displacement., distance - The path length from the start point to the finish point., displacement - The straight line distance from the start point to the finish point with an associated direction., resultant - The equivalent to the combined effect of two or more component vectors acting at the same point., acceleration - The rate of change in velocity., force - The interaction between objects that causes them to change speed, direction and/or shape., Newton’s First Law of Motion - An object will continue to travel at a constant speed in a straight line (at a constant velocity) unless it is acted on by an unbalanced force., Newton’s Second Law of Motion - The acceleration of an object is directly proportional to the magnitude of the unbalanced force acting upon it and inversely proportional to its mass., Newton’s Third Law of Motion - If object A exerts a force on object B, then object B will exert an equal but opposite force on object A., balanced forces - Forces that act in opposite directions but are equal in magnitude. The resultant force is 0 N., unbalanced force - Forces are not balanced and so the resultant force is non-zero., friction - A force that opposes the direction of movement of an object and whose direction acts opposite to that of the direction of motion., weight - The force exerted on an object by the pull of gravity of the Earth., mass - The amount of matter contained within an object., gravitational field strength - The ratio of weight to mass., work done - A measure of the energy transformed. , energy - A measure of the ability of a system to do work. , power - The rate at which appliances transform energy (change it from one form to another)., law of conservation of energy - Energy cannot be created or destroyed, only transformed from one form into another or transferred from one object to another. , gravitational potential energy - A measure of the work done against gravity., kinetic energy - The energy associated with a moving object. , projectile motion - An object that travels horizontally and vertically at the same time. The object travels at a constant velocity horizontally and accelerates uniformly vertically.,
