Estimate speeds, accelerations, and applied forces in the context of large-scale everyday road transport.
Describe and conduct a practical investigation determining the effect of varying force on an object's acceleration (with constant mass) and the effect of varying mass on acceleration (with constant force).
(HT only) Explain inertial mass as a measure of how difficult it is to alter the velocity of an object.
(HT only) Define inertial mass as the ratio of resultant force to acceleration.
