Vocabulary
A change in an object's position
Motion
A snowflake falling down from the sky.
Gravity
How are position and motion connected?
Motion is a change in an object's position
Acceleration
What does MELTS stand for?
Mechanical Energy, Electrical Energy, Light Energy, Thermal Energy, Sound Energy
The speed and direction of an object
Velocity
A car moving at 55 miles per hour down the road.
How are speed and velocity connected?
Velocity is speed with direction.
The location of an object
Position
What is heat energy?
Thermal
How fast an object's position changes
Speed

Velocity
How are speed and acceleration connected?
Acceleration is when the speed (and direction) of an object changes
The amount of matter in an object (how heavy it is).
Mass
What does happens when energy is transferred?
It goes from one object to another
A force between surfaces that slows objects or stops them from moving
Friction
I moved my fork across the table.
Motion
Why is gravity important for life on Earth?
It keeps things on the Earth so that they don't float away, Sun's gravity keeps Earth at the right distance, etc.
The energy of motion
Kinetic Energy
What does it mean for energy to transform?
It changes from one form of energy to another
A noncontact force that acts over a distance and pulls all objects toward each other
Gravity
Friction
How could I create more friction between my feet and the ground when its icy outside?
Sprinkle sand or salt on the ice, where spiked shoes, etc.
The energy stored inside an object
Potential Energy
Explain the energy transformation taking place when a bowling ball knocks the pins down
mechanical/kinetic energy transforms into sound or heat with hitting the pins and rolling down the alley
