force, F, in newtons, N mass, m, in kilograms, kg acceleration, a, in metres per second squared, m/s2 (HT only) The tendency of objects to continue in their state of rest or of uniform motion is called inertia. Inertial mass is a measure of how difficult it is to change the velocity of an object. Inertial mass is defined by the ratio of force over acceleration. Analyse data on vehicles to determine the acceleration when given the driving force and mass of the vehicle. Explain why two identical cars that have different loads will have different accelerations. Explain why heavier vehicles have greater stopping distances than light vehicles, assuming the same braking force. (HT only) Define inertial mass. (HT only) Explain why it is difficult to get a heavy moving object to lower acceleration than a ball falling through air? Why is it harder to turn a loaded shopping trolley than an empty one? (HT only) How does the mass of a vehicle affect its acceleration? Why do motorcycles have a greater acceleration than cars? Why do cars have a higher top speed than motorcycles even though the motorcycle has less mass? driving force. Use light gates or ticker tape to take accurate measurements and add mass to the trolley. Required practical 14: investigate the effect of varying the force on the acceleration of an object of constant mass and the effect of varying the mass of an object on the acceleration produced by a constant force.
