This video introduces the concept of gravity to students. It would be useful to use as a hook or consolidation tool.

This video is almost 15 minutes long, but it may be useful for relief classes or where there is some time to spare. Perhaps students could complete a worksheet in addition to watching this video so that they can show their understanding.

This site provides a number of useful resources and materials which align to the Australian Curriculum.

This resource contains some really useful videos, including one where Dr Brian Cox visits a vacuum chamber. It would a be a great video to show students the effect of gravity.

Force field, gravitational force, gravity, mass, terminal velocity, weight.

Theory:
Gravity is a non contact force that acts over long distances. It is directed into the centre of objects.

All objects with mass have gravity. Even you!! The more mass = more gravity.

Great video showing what gravity looks like

Weight is defined as the gravitational force on an object. Weight is a force measured in Newtons (N). It changes depending on where the object is.

Mass is defined as the amount of matter an object contains. It is measured in kilograms (kg) and is doesnt change anywhere in the universe. See below for an example.

Go here, enter your weight and see how much you weigh on other planets. Write this down.

Fill in the weight the masses would appear on different planets. (Copy this table in your workbook)

Hint: multiply mass by the number in brackets. (the number in the brackets is the acceleration of gravity)

Terminal velocity is the fastest speed a specific object reaches when falling. It happens becuase the gravity force and the air resistance force are balanced, they are the same. The faster an object falls the higher the air resistance.

What happens if there is no air friction when objects are dropped at the same time???????????????

Can you do Q1-8, 10, 12-16

I can describe gravity.

I can compare mass and weight.

I can explain terminal velocity.

I can describe what would happen if 2 objects were dropped with no air friction present.

This interactive tool creates a great visual for student to assist them with grasping the concept of the Sun's pull on Earth, and how this impacts our orbit. There are options to modify the mass of the star or the planet, as well as other tools to highlight key concepts.
