Physics Motion Flashcards
Distance
To find distance, speed is beside time, so distance is speed multiplied by time.
Speed
To find the speed, distance is over time in the triangle, so speed is distance divided by time.
Meters
The Meter is the basic unit of length in the SI system of units
Speed
Speed is the distance traveled per unit of time
Magnets
Pieces of metal that attract other substances.
Magnet Material
Materials magnets attract. For example, iron, steel, cobalt and nickel, as well as other magnets.
Alloy
A mixture of two metals. Steel contains iron and cobalt
Distance-time graph
Graph drawn using time on x axis and distance on y axis. The slope gives the speed
Current electricity
The steady flow of charge though wires and circuits.
Static electricity
When two objects come into contact, electrons can transfer between them. When this happens, both objects become charged with static electricity.
Charged particles
Particles that have lost or gained electrons.
Conductors
Particles that have lost or gained electrons.
Insulator
A substance that does not allow energy, such as heat or electricity, to pass through it easily.
Negative
Electrons have a negative charge. If an object gains electrons, it becomes negatively charged.
Positive
An object that has lost electrons takes on a positive charge.
