Topics covered

• Naming and labelling different types of forces.
• Forces can change the speed of a moving object, change the direction of a moving object and change the shape of an object
• Adding simple forces along a straight line
• Stationary objects have balanced forces acting on them.
• Labelling Newton's third law paired forces in a range of situations.
• Newton's third law paired forces act on different objects and therefore do not cancel.
• The plum pudding model of the atom
• Observations drawn from the Geiger Marsden experiment
• Conclusions made which led to the Rutherford model of the atom
• States of matter can be classified in terms of their characteristics e.g. compressibility, ease of flow, maintenance of shape and volume.
• The change of state of Butyl Stearate.
• Characteristics of BS in solid and in liquid forms.
• Temperature doesn’t change during a change of state.
• The molecules of the liquid must overcome the forces of attraction between them.
• The temperature of a boiling liquid remains constant, even when more heat is added.
