Gravity
A force of attraction that exists between any objects with mass
Force
a push or pull exerted by one object on another causing a change in motion
Conduction
the transfer of energy by direct contact of molecules
Inertia
the tendency of an object to oppose a change in motion
Acceleration
the change in velocity of a moving object with time
Velocity
the speed and direction of a moving object
Momentum
the mass of an object multiplied by itsvelocity
Convection
the transfer of heat energy by the flow of a liquid or gas
Friction
a force that opposes motion of an onject in contact with a surface
Balanced Forces
Forces that cancel each other out when acting together on a single object
Net Force
The combined effect of all of the forces acting on an object
Kinetic Energy
the energy of a moving object
Potential Energy
the energy that is stored in an object or material

What is the difference between Velocity and Speed?
Velocity - is speed and direction of a moving object

Speed - is how fast an objects position changes with time at any given moment

What is the difference between Kinetic and Potential eneregy?
Kinetic - is energy of a moving object

Potential - is the energy that is stored in an object or material

Give examples of Kinetic energy
car moving down the street

bowling ball going down the alley

Give examples of Potential energy
a battery

big heavy weight about to fall

Draw a roller coaster and put an X on the spot that has the most potential energy and an O on the spot that has the most Kinetic energy
Draw
