Objects that contain chemicals that can react, have a chemical store of energy.

Objects have a thermal store of energy because of their temperature.

Objects that are moving have a kinetic store of energy.

Objects that are raised up have a gravitational store of energy.

Objects that are stretched or squashed have an elastic store of energy.

Transferring energy

In the Hidden forces unit, they will build on this knowledge to learn about turning forces, forces that hold objects on a surface, and those that make some objects float.

In primary science, pupils learnt that air resistance, water resistance and friction push back against moving objects. 

This unit focuses on quantifying and comparing energy transfers in different processes, such as motion changes, electrical circuits, and fuel burning. It examines forces as interactions between objects, using diagrams and measurements, including contact and non-contact forces.

Forces

We say objects have energy when they have certain properties.

If the object contains chemicals that can react.

Which of the below properties mean an object has energy?

When an object has energy, we say it has a {{}} of energy.

objects that contain chemicals that can react

Match each reason an object can have energy to the correct name of each energy store.

Identify the energy stores that a moving aeroplane has.

If a stretched elastic band is slowly allowed to become slack again.

Which of these increase the stored energy?

The word 'energy' has a scientific meaning, but also has non-scientific meanings in everyday life. Which pupil is using the word energy with it's proper scientific meaning?

Which do you think would have more energy?

Which do you think has most energy due to its movement?

Starting with the least energy, sort these food items into order of increasing energy content.
