Natural Sciences Grade 7 Term 3: Energy and Change Potential and kinetic energy

Topic 2 Potential and kinetic energy What is energy? Natural Sciences - Grade 7

Natural Sciences - Grade 7 What is energy? Energy is the ability to do work. Energy cannot be created or destroyed. It is only changed from one type of energy to another. The sun is our main source of energy. Energy can be divided into two main forms, namely potential and kinetic energy. Natural Sciences - Grade 7

Natural Sciences - Grade 7 Energy Energy is all around us - most of the time we are not even aware of it. Plants use the light energy from the sun to make food during photosynthesis. Animals and plants need food to get energy for all living processes. Natural Sciences - Grade 7

Natural Sciences - Grade 7 Energy Wind is air particles in motion because the particles have energy. The sounds we hear is also a form energy. We burn coal and other fuels to release energy. Natural Sciences - Grade 7

Natural Sciences - Grade 7 The different types of energy There are five different types of energy: Heat Chemical Electromagnetic Nuclear Mechanical Natural Sciences - Grade 7

Natural Sciences - Grade 7 Two main forms of energy All energy types can be divided into two main forms: Potential energy - Energy that is stored within objects or systems. Kinetic energy - Energy possessed by objects or a system as a result of movement. Natural Sciences - Grade 7

Examples of potential energy Chemical energy that can change to electrical energy when using a cell. Elastic energy when a rubber band is stretched. Gravitational potential energy. The ball and the brick gain energy when lifted from the ground. Natural Sciences - Grade 7

Natural Sciences - Grade 7 Examples of kinetic energy A pogo stick, when someone jumps on it, has kinetic energy, due to its motion. A racing motorcycle has lots of kinetic energy. Can you think of other examples of moving objects or systems? The ball gains kinetic energy when kicked. Natural Sciences - Grade 7

Natural Sciences - Grade 7 A closer look at gravitational potential energy All objects (matter) will experience the force of gravity. Gravity is the force causing all objects to fall to the ground. The higher an objected is lifted, the greater the potential energy. The heavier an object, the greater its potential energy. Natural Sciences - Grade 7

Natural Sciences - Grade 7 A closer look at gravitational potential energy When the object falls to the ground, the potential energy changes into kinetic energy (because it moves). When the object rests on the ground, it has no potential energy. Natural Sciences - Grade 7
