Little little into the middle
Amount of stretch gets longer when you stretch it.
What is extension?
A fast moving car has more than a slow moving car.
SI unit of the energy
What is joule?
The force of attraction between two objects because of their mass.
What is gravitational force?
Force from an engine or rocket
What is thrust?
Device that change light energy into electrical energy.
What is solar cell?
Energy transferred by sources such as Sun and light bulbs
What is light energy?
A fossil fuel formed from sea creatures over millions of years
What is oil?
The force on an object that is moving through the air, causing it to slow down.
What is air resistance?
A force that resists movement because of contact between surfaces.
What is friction?
When you stretch an elastic object until this limit and let it go, it goes back to its original state.
What is elastic limit?
Energy stored in an elastic object that is stretched or compressed.
What is elastic potential energy?
A fossil fuel formed from dead plants that have been buried underground over millions of years.
What is coal?
This energy type turns into kinetic energy when you are falling.
What is gravitational potential energy?
The force on an object moving through water that causes it to slow down.
What is water resistance?
When this force is present:
If an object is stationary, it continues to stop.
If an object is moving, it continues to move with constant speed.
What is balanced forces?
Energy that is transferred from a cell or battery to the components of a circuit.
What is electrical energy?
The process by which green plants make their own food from carbon dioxide and water by using solar energy
What is photosynthesis?
Kinetic energy turns into this energy type when you are bungee jumping.
What is Elastic Potential Energy?
The force on an object in a liquid or gas that pushes it up.
What is upthrust?
When this force is present:
If an object is stationary, it starts moving.
If an object is moving, it can accelerate, decelerate, stop, or change direction.
What is unbalanced forces?
Energy stored in fuels, food and electrical batteries
What is chemical energy?
When air resistance and weight of an object get equal to each other, net force acting on the object becomes zero and it falls with constant speed.
What is terminal velocity?
The force between two charged objects
What is electrostatic force?
