Motion with non-uniform acceleration
Explore motion with non-uniform acceleration within forces in action. Start with the object and draw all forces acting on it. Their vector sum determines acceleration; zero resultant force gives constant velocity, including rest.
Specification outcomes (5)
- 3.2.2(a) Define drag as the frictional force experienced by an object travelling through a fluid.
