This episode discusses: linear and angular velocity; degrees and radians; and angular acceleration. And is accompanied by...

Lesson 16-19

This episode starts by considering the forces acting on a falling body in air, and moves on to related experimental work.

Lesson 16-19

This episode continues to look at basic kinematics and introduces the equations of motion for uniform acceleration. This...

Lesson 16-19

This episode looks at the independence of vertical and horizontal motion. It concerns objects accelerating vertically when...

Lesson 16-19

This episode introduces the concept of momentum and its conservation.

Lesson 16-19

This episode extends the idea of conservation of momentum to elastic collisions, in which, because energy stored kinetically...

Lesson 16-19

This episode focuses on the forces involved in changing momentum, and introduces the concept of impulse.

Lesson 16-19

This episode concerns Newton’s second law. Your students will probably have met the second law in the form F = m a ; many will...
