What is the difference between a scalar and a vector quantity, Scalar has magnitude, vector has magnitude and direction, Give one example each of a scalar and a vector, Mass is scalar, force is vector, What does Newton's first law say about a moving object, Object at rest remains at rest. Object in motion continues at constant velocity, What resultant force acts on an object moving at constant velocity, Zero resultant force, State the relationship between force, mass and acceleration, Force equals mass times acceleration, If the same force acts on a larger mass, what happens to acceleration, Acceleration decreases, What is the unit of force, Newton, How is one newton defined, Causes 1 kg to accelerate 1 m/s², What is meant by inertia, Resistance to change in motion, Why does a loaded lorry have greater inertia than an empty one, It has greater mass, In the tip to tail method, where is the second vector placed, At the tip of first, In the tip to tail method, how is the resultant vector drawn, From first tail to last tip
