5.1 Forms of Energy
Define energy and it's two types.
Energy is the ability to cause change. It's two types are Kinetic (KE) and Potential (PE) energies.
Define Law of Conservation of Energy.
Law of Conservation of energy states that energy can be transformed from one form to another or transferred form one region to another, but energy cannot be created or destroyed.
What are the 3 forms about Potential energy?
1. Gravitational
2. Elastic
3. Chemical
Define Friction and give an example.
Friction is a force that resists the sliding of two surfaces that are touching. An example of friction is sliding a box across the floor.
What is work and give an example.
Work is the transfer of energy that occurs when a force is applied over a distance. An example of work is lifting a barbell.
Name the energy transformations that occur in a Microwave.
Electric energy - Radiant (Electromagnetic) energy - Thermal energy.
What are the 6 forms of energy?
Mechanical, Sound, Thermal, Electric, Radiant/Light, and Nuclear energies.
Name 3 ways that we use energy in our daily lives.
1. Transportation
2. Lighting and heating our homes.
3. Running appliances
When a ball is thrown high in the air, where does it have the least KE?
At the highest (top) point.
What do sceientist often refer to as Thermal energy?
Waste energy
