Forces and Motion

Demonstration: Principles of physics are not just abstract. They have practical value.

Practical Activity 14-16

Class practical: Science can reveal simple patterns with considerable predictive power. This is of huge practical value...

Practical Activity 14-16

Class practical: In a streamline flow, fluid pressure will be reduced in a region where the flow velocity is increased, for...

Practical Activity 14-16

Class practical: Experiment to flatten the water curvature inside a capillary tube.

Practical Activity 14-16

Demonstration: The higher the viscosity of a liquid the more it resists motion of a body through it. The result can be very...

Practical Activity 14-16

Class practical: Ideas about terminal velocity and about streamlining can be quite difficult. This gives students some...

Practical Activity 14-16

Class practical: An object falling through water reaches a constant terminal velocity after falling relatively small distances...

Practical Activity 14-16

Demonstration: This is an exploration of which factors affect the force of friction when one surface slides across another and...

Practical Activity 14-16

Demonstration: It is quick and simple to demonstrate that surface tension gives droplets a spherical shape.

Practical Activity 14-16

Demonstration: In this experiment aniline drops grow in water. Apparently weightless (because aniline density is almost the...

Practical Activity 14-16

Class practical: Surface tension in a liquid is an intrinsically interesting phenomenon. It also provides evidence in the...

Practical Activity 14-16

Class practical: This is a fun challenge, ideal as an extension activity or just for some mind-stretching for its own sake.
