Momentum activity (BBC Bitesize)
Watch the animation on momentum and how it applies to situations.

Crumple Zones (BBC Bitesize)
Read all about momentum and its link to force and car safety. Then try the test!

Momentum (BBC Bitesize)
Read all about momentum and how to do calculations involving conservation of momentum. Then try the activity and do the test!

Gigantic balloon experiment
Watch the video that shows that the air inside the balloon has mass.

Amazing bouncing balls experiment
Drop two balls and see what happens! Then read the explanation of the physics of it.

Moon olympics!
What would it be like to play sports on the Moon?

Conservation of momentum animation
Vary the mass, velocity and type of collision and look at whether momentum and kinetic energy are conserved.

Bump! Momentum animation (PhysLab)
Two skaters on frictionless ice can be made to collide at different speeds. They can also be given different masses to carry. Velocity, momentum and kinetic energy are calculated before and after each collision.

Lunar Lander Game
Can you land the lunar lander safely? Change the thrust and find as many safe landing sites as you can.

Momentum from The Physics Classroom
Read through each section and then check your understanding by doing the questions at the end. Then check out the animations in the Multimedia Studios on the site for more help.

Elasticity and Hooke's Law (BBC Bitesize)
Read all about elastic materials and Hooke's Law. Then do the test!

Mechanics at a Glance (School Physics)
Find out about speed, acceleration, circular motion, kinetic and potential energy, Newton's Laws, work and power, and velocity.

Elastic collision animation (School Physics)
Watch the animation that shows an elastic collision between two trolleys of equal mass

Inelastic collision animation (School Physics)
Watch the animation that shows what happens in an inelastic collision.

Explosion animation - unequal masses (School Physics)
Watch an animation that show an explosion of two trolley on unequal mass.

Experiments to show conservation of momentum (Practical Physics)
How to do an experiment to show conservation of momentum.
